Add a line after another line in multiple files - regex

I have opened 100 files like this:
[database]
server=SQL01
db=milli
authentication=auServer
[Misc]
Now I need to add the same line like this
[database]
server=SQL01
db=milli
authentication=auServer
username=user1
[Misc]
How can I do this, probably some sort of regex?

You could simply do this with Notepad++ using the Find in Files feature.
Put authentication=auServer in the Find what text box, authentication=auServer\r\nusername=user1 in the Replace with text box, *.* in the Filters drop down, C:\some directory in the Directory drop down, tick the In all sub-folders check box, and switch the Search Mode to Extended.
Then just click Replace in Files and you're done.

You could try using the Find in files tab on the search dialogue. Make sure Regular expression selected. Set the search string to (db=milli\r\nauthentication=auServer\r\n)(\r\n\[Misc\]) and the replacement to \1username=user1\r\n\2. Then click Replace in files.
Note that the above will add the line in ALL matching places in the files. To specify the files use the Filter and Directory fields, also make sure that the three tick boxes beneath the Close button are correct.
The Replace in files should be avoided unless you are confident that it will not destroy your files.

Regex/Notepad++ to extract text from file

I have multiple files with text in parenthesis that I need to extract from the file (or delete everything else in that file). I have a method that works, but it only works for one file. Here is an example of the kind of files I'm dealing with.
(is it on?)
[3.87595 3.87595 0 ]xsh
grestore
NDTMRY+Helvetica[8.5 0 0 -8.5 0 0 ]msf
mo
(NO)
The method I have used is as follows:
in notepad++ under the mark tab in find replace; Find: ^(.*?$ (with bookmark line checked)
Search>bookmarks>remove unbookmarked lines
Is there a way/better way to do this for multiple files at a time? In this or another language such as python.
Thanks!
Yes, it is possible to remove in multiple files lines that do not start with (.
Here is the screenshot with settings:
So, here are the instructions:
Press Ctrl+H and click Find in Files
In Find What, type ^(?!\().*\R*, keep Replace With empty
Add file masks in Filters
Select the initial directory in Directory.
Make sure Regular expression radio button is selected.
Adjust other options and hit Replace in Files button.

How do I find and replace all occurrences (in all files) in Visual Studio Code?

I can't figure out how to find and replace all occurrences of a word in different files using Visual Studio Code version 1.0.
I get the impression this should be possible since doing Ctrl + Shift + F allows me to simply search a folder, but i am clueless to how to proceed from here.
I looked in various key combination
https://code.visualstudio.com/Docs/customization/keybindings
But I only found how to replace all occurrences in the open file (Ctrl + h)
All help gratefully appreciated, this is driving me crazy.
I'm using Visual Studio Code 1.8, and this feature is available. But it's a little tricky to understand at first, and (at the time of writing) the docs don't explain clearly how to use it, so here's how it works, step by step:
Invoke Replace in Files (under the Edit menu, or with shortcut Ctrl+Shift+H)
You'll see a standard Find/Replace input replacing the files pane on the left:
Enter your search string and the replace string, then press enter. It may churn for a second searching all files, then it'll show the proposed changes in all your project files -- but note, these changes haven't been made yet! Here's what it looks like:
Now you need to make the changes (and even after that, you have to save the modified files.)
You can make those changes in various ways:
Make all changes to all files at once.
Click the replace icon next to your replace string (note: you'll get a dialog to confirm this bulk action.)
Make all changes in a single file at once.
Click the replace icon next to the filename (note: the icon only shows up when you hover over the filename row)
Make a single change in a single file.
Click the replace icon next to the individual change: (note: the icon only shows up when you hover over the change row)
Finally, don't forget to save!
All those files are now modified in the editor and not yet saved to disk (unless Auto Save is on).
Use File -> Save All (or Ctrl+Alt+S)
Update: I'm not sure when this was added, but if you click the "Replace all" button and see this dialog, clicking "Replace" will change and save all files in one click:
Since version 1.3 of vscode this is possible
Navigate to the search, click icon to the left or:
(mac) cmd + shift + h
(PC) ctrl + shift + h
expand replace
enter search term and replace term
confirm!
To replace a string in a single file (currently opened): CTRL + H
For replacing at workspace level use: CTRL + SHIFT + H
Update for 2020
If you are using the search feature to search across files (Ctrl + Shift + F) it can be easy to miss how to convert your search to a search and replace within the UI.
Here's a typical search result:
To convert this to a search and replace you need to click the arrow icon to the left of the search input field. This will open the replace options as seen below. Note the arrow icon is now pointed down.
The keyboard shortcut Ctrl + Shift + H will also work as well to access the search and replace.
Link to VSCode docs on search and replace: https://code.visualstudio.com/docs/editor/codebasics#_search-and-replace
This is the best way.
First put your cursor on the member and click F2.
Then type the new name and hit the Enter key. This will rename all of the occurrences in every file in your project.
This is ideal for when you want to rename across multiple files. For example, you may want to rename a publicly accessible function on an Angular service and have everywhere that uses it get updated.
For more great tools I highly recommend:
https://johnpapa.net/refactoring-with-visual-studio-code/
On the Visual Studio Code Key Bindings page, the section Keyboard Shortcuts Reference has links to a PDF for each major OS. Once open, search for "replace in files" or any other shortcut you might need.
Another way is to use the Command Palette (ctrl/cmd+shift+P) where you can type "replace" to list all related commands, including the one you want:
Replace in Files ctrl/cmd+shift+H
Visual Studio Code: Version: 1.53.2
If you are looking for the answer in 2021 (like I was), the answer is here on the Microsoft website but honestly hard to follow.
Go to Edit > Replace in Files
From there it is similar to the search funtionality for a single file.
I changed the name of a class I was using across files and this worked perfectly.
Note: If you cannot find the Replace in Files option, first click on the Search icon (magnifying glass) and then it will appear.
There are 2 methods technically same
First put your cursor on the word and press F2.
Replace your word and press Enter.
First put your cursor on the word and left click it.
Click "Rename Symbol" option.
Replace your word and press Enter.
In the VSC version 1.57
you can use the F2 key to replace on the folder(Rename Symbol)
Only thing is that even though all the places inside folder are replaced the file is not saved and the save has to be done afterwards
Also, instead of presing enter and replace all directly, you can press Shift + Enter to preview the places that are going to be renamed.
Step by step with images
Nowadays in VS Code this can be done quickly.
1) Click on the Search Button (in the side bar):
2) Enter in the inputs what do you want to find, and with what do you want to replace it:
(Here I am replacing in my project all the occurrences of table-cell with t-cell)
3) Finally, click on this small button (Replace All):
Then a pop-up will appear to confirm if you want to replace all occurrences. Click on Replace.
And you're done!
For search and replace all use this command:
command + option + F

Search for multiple strings in several files with Sublime 3 using AND

This previous (similar) question of mine Search for multiple strings in several files with Sublime 3 was answered with a way to search for multiple strings in multiple files in SublimeText, using the regex OR operator:
Find: (string1|string2)
Where: <open folders>
This works perfectly for searching files where either string1 OR string2 is present. What I need now is to search in lots of files for both strings present. I.e., I need to use the AND operator.
I looked around this question Regular Expressions: Is there an AND operator? and also this one Regex AND operator and came up with the following recipes:
(?=string1)(?=string2)
(?=.*string1)(?=.*string2)
(string1 string2)
(string1\&string2)
but none of them work.
So the question is: how can I search multiple strings in several files at once with SublimeText?
(I'm using SublimeText 3103)
Add: the strings are not necessarily in the same line. They can be located anywhere within each file. For example, this file:
string1 dfgdfg d dfgdf
sadasd
asdasd
dfgdfg string2 dfgdfg
should trigger a match.
Open sublime Text and press
Shift+Ctrl+F
or click on the Find in Files options under Files tab. The above is keyboard shortcut for this option. When you press above key, these are following options
When you select ... button from above, you get 6 options which are Add Folder or Add Open Files or Add Open Folders
To search strings that occur in the same line
Use the following regex for your and operation
(?=.*string1)(?=.*string2)
I am using the following regex
(?=.*def)(?=.*s)\w+ <-- \w+ will help in understanding which line is matched(will see later)
and I am searching within current open files
Make sure the Use Buffer option is enabled (one just before Find). It will display the matches in a new file. Also make sure the Show Context (one just before Use Buffer) option is enabled. This will display the exact line that matches. Now Click on Find on the right side.
Here is the output I am getting
See the difference in background color of line 1315 and 1316(appearing in left side). 1316 is matched line in designation file
This is the image of last part
There were total 6 files that were opened while I used this regex
For finding strings anywhere in file
Use
(?=[\s\S]*string1)(?=[\s\S]*string2)[\s\S]+
but it will kill sublime if number of lines increases.
If there are only two words that you need to find, the following will work super fast in comparison to above
(\bstring1\b[\S\s]*\bstring2\b)|(\bstring2\b[\S\s]*\bstring1\b)

Compare files and return only the differences using Notepad++

Notepad++ has a Compare Plugin tool for comparing text files, which operates like this:
Launch Notepad++ and open the two files you wish to run a comparison
check on.
Click the “Plugins” menu,
Select “Compare” and click “Compare.”
The plugin will run a comparison check and display the two files side
by side, with any differences in the text highlighted.
This is a nice feature, and which I have used happily for some time. Now, I have been looking for an option to go further and select the highlighted differing lines (e.g. by deleting the non-highlighted ones), or vice versa: i.e. expunge the highlighted lines.
Is there a straightforward way to achieve this?
To substract two files in notepad++ (file1 - file2) you may follow this procedure:
Recommended: If possible, remove duplicates on both files, specially if the files are big. To do this: Edit => Line operations => Sort Lines Lexicographically Ascending (do it on both files)
Add ---------------------------- as a footer on file1 (add at least 10 dashes). This is the marker line that separates file1 content from file2.
Then copy the contents of file2 to the end of file1 (after the marker)
Control + H
Search: (?m-s)^(?:-{10,}+\R[\s\S]*+|(.*+)\R(?=(?:(?!^-{10,}$)-++|[^-]*+)*+^-{10,}+\R(?:^.*+\R)*?\1(?:\R|\z))) note: use case sensitivity according to your needs
Replace by: (leave empty)
Select Regular expression radio button
Replace All
You can modify the marker if It is possible that file1/file2 can have lines equal to the marker. In that case you will have to adapt the regular expression.
By the way, you could even record a macro to do all steps (add the marker, switch to file2, copy content to file1, apply the regex with a single button press.
Edited:
Changed the regex to add some improvements:
Speed related:
Avoid as much backtracking as possible
Avoid searching after the mark
Usability:
Dashes are allowed for the lines. But the separator is still ^-{10,}$
Works with other characters besides words
Speed comparison:
New method vs Old method
So basically 78ms vs 1.6seconds. So a nice improvement! That makes comparing Kilobyte-sized files possible.
Still you may want to use some dedicated program for comparing or substracting bigger files.
If the number of differences is not large, a quicker method might be just bookmarking each differing line using keyboard shortcuts. Starting from the beginning of the file, press Alt+Page Down to focus on the first difference, and then press Ctrl+F2 to bookmark it. Continue with alternatingly pressing Alt+Page Down and Ctrl+F2 until the last difference.
With all the differing lines bookmarked, you can use any of the operations under "Search -> Bookmarks" menu:
Cut Bookmarked Lines
Copy Bookmarked Lines
Paste to (Replace) Bookmarked Lines
Remove Bookmarked Lines
Remove Unmarked Lines
I have a dirty workaround for this. It saves some time compared to Control+C, Alt+Tab, Control+V; Control+C, Alt+Tab, Control+V; ... but It may not be worth on big files or if the differences for both files are big. For bigger files you may prefer using some other tool.
Typically this works best when comparing group of 'words' and does not work with content that is tabulated (like source code)
So the workaround is:
Optional: (depends on the content that's being compared) Sort both files (it will make the future comparison easier) To do this: Edit => Line operations => Sort Lines Lexicographically Ascending (do it on both files)
Compare files with the plugin
Choose one file and inspect the lines you want to keep. Add one tabulator before each of those lines. Remeber you can select several lines and press tab for tabulating them. Optionally, you may add tabulators to the lines you want to remove
Sort the file. The tabulated lines will come up first. So now you can copy-paste them (or copy-paste the untabulated ones)
move the files to a linux box and then execute diff command:
$ diff file1.txt file2.txt > file_diff.txt

Can Notepad++ save out search results to a text file?

I need to do quite a few regular expression search/replaces throughout hundreds and hundreds of static files. I'm looking to build an audit trail so I at least know what files were touched by what searches/replaces.
I can do my regular expression searches in Notepad++ and it gives me file names/paths and number of hits in each file. It also gives me the line #s which I don't really care that much about.
What I really want is a separate text file of the file names/paths. The # of hits in each file would be a nice addition, but really it's just a list of file names/paths that I'm after.
In Notepad++'s search results pane, I can do a right click and copy, but that includes all the line #s and code which is just too much noise, especially when you're getting hundreds of matches.
Anyone know how I can get these results to just the file name/paths? I'm after something like:
/about/foo.html
/about/bar.html
/faq/2012/awesome.html
/faq/2013/awesomer.html
/foo/bar/baz/wee.html
etc.
Then I can name that file regex_whatever_search.txt and at the top of it include the regex used for the search and replace. Below that, I've got my list of files it touched.
UPDATE What looks like the easiest thing to do (at least that I've found) is to just copy all the search results into a new text file and run the following regex:
^\tLine.+$
And replace that with an empty string. That'll give you just the file path and hit counts with a lot of empty space between each entry. Then run the following regex:
\s+\n
And replace with:
\n
That'll strip out all the unwanted empty space and you'll be left with a nice list.
maybe you need power of unix tools
assume you have GNUWin32 installed in c:\tools\gnuwin32
than if you have replace.bat file with that content:
#echo off
set BIN=c:\tools\gnuwin32\bin
set WHAT=%1
set TOWHAT=%2
set MASK=%3
rem Removing quotes
SET WHAT=###%WHAT%###
SET WHAT=%WHAT:"###=%
SET WHAT=%WHAT:###"=%
SET WHAT=%WHAT:###=%
SET TOWHAT=###%TOWHAT%###
SET TOWHAT=%TOWHAT:"###=%
SET TOWHAT=%TOWHAT:###"=%
SET TOWHAT=%TOWHAT:###=%
SET MASK=###%MASK%###
SET MASK=%MASK:"###=%
SET MASK=%MASK:###"=%
SET MASK=%MASK:###=%
echo %WHAT% replaces to %TOWHAT%
rem printing matching files
%BIN%\grep -r -c "%WHAT%" %MASK%
rem actual replace
%BIN%\find %MASK% -type f -exec %BIN%\sed -i "s/%WHAT%/%TOWHAT%/g" {} +
you can do regex replace in masked files recursively with output you required
replace "using System.Windows" "using Nothing" *.cs
The regulat expression I use for this kind of problem is
^\tLine.[0-9]*:.
And it works for me
This works well if you have Excel available and want to avoid using regular expressions:
Ctrl+A to select all the results
drag & drop the selected results to Excel
Create a Filter on the 1st row
Filter out the lines that have "(Blank)" on the 1st column
Select the remaining lines (i.e. the lines with the filenames) and copy/paste them to another sheet or any wanted destination
You could also Ctrl+A, Ctrl+C the search results, then use the Paste Option "Use Text Import Wizard" in Excel, say that the data is "Fixed width" and put one single break line after the 2nd character (to remove the two leading spaces in the filename during import), and use a filter to filter out the unwanted rows.
