I am trying to extract tokens from a list of strings using a batch script, but for some reason it ignores my string if it contains an asterisk.
An example to illustrate this problem is as follows:
#echo off
set mylist="test1a,test1b"
set mylist="test2a,test2b*" %mylist%
set mylist="test3a,test3b" %mylist%
echo %mylist%
for %%a in ( %mylist% ) do (
for /F "tokens=1,2 delims=," %%i in ( %%a ) do (
echo %%i
echo %%j
)
)
I would expect this to print out all six tokens but instead it only prints test3a, test3b, test1a, and test1b, like it is ignoring the second string completely.
The placement of the asterisk within the second string doesn't seem to matter, but if I remove it everything works as I expect.
Does anyone know what is going on here?
Got it. The interpreter is trying to match a filename. If you change "test2a,test2b*" by pp.* and create a file named pp.txt (same dir) your script will proces the contents of pp.txt

I have file.txt where I have values in format:
text1
text2
text3
Anyone have the idea to open such a file in a script and modify it to
'text1','text2','text3'
so far i have done it manually in notepad++ but i'd rather put it in some script just don't know how:
first step:
find what: ^|$
replace with: '
and
second step:
find what: [\r\n]+
replace with: ,
You want to convert a file with lines into a single-line file, where the single (original) lines are single-quoted and separated by a comma.
Not very efficient, but straightforward:
#echo off
set "infile=input.txt"
set "outfile=output.txt"
del "%outfile%" 2>nul
for /f "usebackq delims=" %%a in ("%infile%") do (
if not exist "%outfile%" (
<nul set /p "='%%a'" > "%outfile%
) else (
<nul set /p "=,'%%a'" >>"%outfile%"
)
)
>>"%outfile%" echo(
type "%outfile%"
Take line by line, if it's the first line, write the quoted value, else write a comma plus the quoted value, both with the <nul set /p trick to write without a linefeed.
I'm trying to capitalize the first letter of the output from the %COMPUTERNAME% variable. I have tried the below code which doesn't work.
set host=%COMPUTERNAME%
echo %host% | sed 's/^\(.\)/\1\u\2/g/'
The output should be Beast rather than BEAST or beast
I ever often tend to wrap a powershell command for this:
:: Q:\Test\2018\10\12\SO_52769852.cmd
#Echo off
For /f %%A in ('
Powershell -NoP -C "$Env:COMPUTERNAME.Substring(0,1).ToUpper()+$Env:COMPUTERNAME.Substring(1).ToLower()"
') do set host=%%A
Echo:%host%
Instead of using `SEd`, you could probably do it as a single line using the built-in `Find` command.
#For /F "Tokens=2 Delims=:" %%A In ('"Find "" ":%ComputerName:~,1%" 2>&1"') Do #Echo %%A%ComputerName:~1%
The idea uses a 'quirk' with find.exe, which capitalizes the entire filename in its error message, when it cannot locate a file. I expand the %COMPUTERNAME% variable, asking for just its first character, %ComputerName:~,1%,and precede that with a character which is invalid in a Windows filename, in this case :. If we assume a %COMPUTERNAME% value of iab-desktop, the error message, (stdOut, 2>) from Find "" ":i" would be passed to the Do portion as, File not found - :I. This is the English version string, but that shouldn't matter, because we have asked for the second token delimited by the : character, which will be I. I then prepend that result, stored in %%A to the expanded value of %COMPUTERNAME%, this time asking for all characters except for its first, %ComputerName:~1%. The resulting string will be the value of %COMPTERNAME% with the first character capitalized.
try this:
#echo off
setlocal
set "f_leter=%COMPUTERNAME:~0,1%"
set "the_rest=%COMPUTERNAME:~1%"
call :UpCase %f_leter% f
call ::LoCase %the_rest% rest
set result=%f%%rest%
echo %result%
exit /b %errorlevel%

Here's the sed answer, although I'd recommend #LotPings powershell answer on Windows. Note that for a typical %computername% the more key point of your question is converting all but the first character to lower-case.
set host=%COMPUTERNAME%
echo %host% | sed -r 's/^(.)(.*)/\U\1\L\2/'
I have a script that extracts lines such as :
THIS_IS_A_LINE:=
THIS_IS_A_LINE2:=
and outputs all of the same kind into another .txt file as:
THIS_IS_A_LINE
THIS_IS_A_LINE2
The script is the following:
set "file=%cd%/Config.mak"
set /a i=0
set "regexp=.*:=$"
setlocal enableDelayedExpansion
IF EXIST Source_List.txt del /F Source_List.txt
for /f "usebackq delims=" %%a in ("%file%") do (
set /a i+=1
call set Feature[!i!]=%%a
)
cd .. && cd ..
rem call echo.!Feature[%i%]!
for /L %%N in (1,1,%i%) do (
echo(!Feature[%%N]!|findstr /R /C:"%regexp%" >nul && (
call echo FOUND
call set /a j+=1
call set Feature_Disabled[%j%]=!Feature[%%N]:~0,-2!
call echo.!Feature_Disabled[%j%]!>>Source_List.txt
) || (
call echo NOT FOUND
)
)
endlocal
I also have another script that extracts lines such as:
THIS_IS_ANOTHER_LINE:=true
THIS_IS_ANOTHER_LINE2:=true
...
and outputs all of the same kind into another .txt file as:
THIS_IS_ANOTHER_LINE
THIS_IS_ANOTHER_LINE2
...
The script is the following:
set "file=%cd%/Config.mak"
set /a i=0
set "regexp=.*:=true$"
setlocal enableDelayedExpansion
IF EXIST Source_List2.txt del /F Source_List2.txt
for /f "usebackq delims=" %%a in ("%file%") do (
set /a i+=1
call set Feature[!i!]=%%a
)
cd .. && cd ..
rem call echo.!Feature[%i%]!
for /L %%N in (1,1,%i%) do (
echo(!Feature[%%N]!|findstr /R /C:"%regexp%" >nul && (
call echo FOUND
call set /a j+=1
call set Feature_Disabled[%j%]=!Feature[%%N]:~0,-6!
call echo.!Feature_Disabled[%j%]!>>Source_List2.txt
) || (
call echo NOT FOUND
)
)
endlocal
Nevertheless, there is a third kind of lines which contain numerical numbers (also some hexadecimal values), such as:
THIS_IS_AN_UNPROCESSED_LINE:=0xA303
THIS_IS_AN_UNPROCESSED_LINE2:=1943
THIS_IS_AN_UNPROCESSED_LINE3:=HELLO_DOOD_CAN_YOU_PARSE_ME?
So I need the way to extract as well those kind of lines into another .txt file such as:
THIS_IS_AN_UNPROCESSED_LINE:=0xA303
THIS_IS_AN_UNPROCESSED_LINE2:=1943
THIS_IS_AN_UNPROCESSED_LINE3:=HELLO_DOOD_CAN_YOU_PARSE_ME?
So basically extract lines which are not of the kind:
THIS_IS_AN_UNPROCESSED_LINE:=
or
THIS_IS_AN_UNPROCESSED_LINE:=true
but keeping both the sides of the line entry.
I know there must be some trick with the regular expression but I just can't find it out.
You have made your code much more complicated than it needs to be. There is no need to create an array of every line in the file.
If there are no other : or = before the first :=, then you can use FINDSTR to print out all lines that contain a string, followed by :=. FOR /F can capture and parse each matching line into the parts before and after :=, and then IF statements can classify the three different types of lines.
I use n> to open all three output files outside the main code block for improved performance, and then I use the &n> syntax to direct each output to the appropriate, already opened file. I use high numbered file handles to avoid problems described at Why doesn't my stderr redirection end after command finishes? And how do I fix it?.
#echo off
setlocal
set "file=Config.mak"
set /a "empty=7, true=8, unprocessed=9"
%empty%>empty.txt %true%>true.txt %unprocessed%>unprocessed.txt (
for /f "delims=:= tokens=1*" %%A in ('findstr /r "^[^:=][^:=]*:=" "%file%"') do (
if "%%B" equ "" (
>&%empty% (echo %%A)
) else if "%%B" equ "true" (
>&%true% (echo %%A)
) else (
>&%unprocessed% (echo %%A:=%%B)
)
)
)
The above will ignore lines that contain : or = before :=, and it will not work properly if the first character after := is : or =. I'm assuming that should not be a problem.
It should be relatively easy to write a very efficient solution using PowerShell, VBScript, or JScript that eliminates the limitations.
You could also use JREPL.BAT - a powerful and efficient regular expression text processing command line utility. JREPL.BAT is pure script (hybrid batch/JScrpt) that runs natively on any Windows machine from XP onward, no 3rd party exe required. And JREPL is much faster than any pure batch solution, especially if the files are large.
Here is one JREPL solution
#echo off
setlocal
set repl=^
$txt=false;^
if ($2=='') stdout.WriteLine($1);^
else if ($2=='true') stderr.WriteLine($1);^
else $txt=$0;
call jrepl "^(.+):=(.*)$" "%repl%" /jmatchq^
/f Config.mak /o unprocessed.txt >empty.txt 2>true.txt
If all you have to do is classify the lines into three different files, without worrying about stripping off the :=true and := parts for the empty and true lines, then there is a very simple pure batch solution using nothing but FINDSTR.
#echo off
set "file=Config.mak"
findstr /r ".:=$" "%file%" >empty.txt
findstr /r ".:=true$" "%file%" >true.txt
findstr /r ".:=" "%file%" | findstr /r /v ":=$ :=true$" >unprocessed.txt
Thanks in Advance.
Using a DOS batch file, I am trying to read a text file that contains several full paths with quotes, separated by a space and write a new file containing one path per line.
For example, I want to turn this file:
"C:\path\filename.doc" "C:\path\filename.doc" "C:\path\filename.doc" "C:\path\filename.doc"
into this:
"C:\path\filename.doc"
"C:\path\filename.doc"
"C:\path\filename.doc"
"C:\path\filename.doc"
I have had some success using the wonderful repl.bat (by dbenham).
type "files.txt" | repl " " "\r\n" x l >"newfile.txt"
But when there are spaces in the filenames or path it breaks a new line in the middle of the path and wrecks it.
Ive tried passing as the search variable into repl using the escape character ^, i.e. repl "^" ^"" and other ways with no joy.
At the end of the day, I simply need to move all the files into another directory, and so was going to then pass the resulting text file to another bulk delete batch file for processing, but perhaps there is a better way im missing ?
This has a limitation in the length of the line, of around 8 KB.
Less than that and it will move the files to your new folder.
#echo off
for /f "usebackq delims=" %%a in ("c:\folder\file.txt") do (
for %%b in (%%a) do move "%%~b" "d:\existing\new\folder"
)
The code below should work to move all files in except the ones in the list.
It adds a hidden attribute to the files in the list, moves all the other files, then removes the hidden attributes again.
#echo off
for /f "usebackq delims=" %%a in ("c:\folder\file.txt") do (
for %%b in (%%a) do attrib +h "%%~b"
)
cd /d "c:\folder"
move *.* "d:\already\existing folder"
for /f "usebackq delims=" %%a in ("c:\folder\file.txt") do (
for %%b in (%%a) do attrib -h "%%~b"
)
Test code for Windows 2012 as mentioned in the comments
#echo off
(echo "c:\widget1\test 1.txt" "2:\widget2\test 2.doc")>"file.txt"
for /f "usebackq delims=" %%a in ("file.txt") do (
for %%b in (%%a) do echo move "%%~b" "d:\existing\new\folder"
)
pause
You could use the following batch file split.bat and call it redirecting the content of your text file into it and redirecting the output into another file like split.bat < files.txt > newfiles.txt:
#echo off
set /P INFILE=
call :SPLIT %INFILE%
exit /B
:SPLIT
shift
if "%~0"=="" exit /B
echo "%~0"
goto :SPLIT
If you do not provide an input file (< files.txt) the scripts prompts you for a space-separated list.
If no output file is given (> newfiles.txt), the created new-line-separated list is shown on screen.
Notice that this does not verify whether your input file fulfills the described formatting.
This method is limited to a list length of 1021 bytes (characters), everything after will be truncated!
Assuming you can guarantee that each file path is enclosed within double quotes, then you just need to tweak your REPL.BAT command a bit:
type "files.txt" | repl "(\q.*?\q) *" "$1\r\n" x >"newfile.txt"
But REPL.BAT has been superseded by JREPL.BAT - it has even more functionality, and a slightly different syntax.
A JREPL solution can be as simple as:
jrepl "\q.*?\q" $0 /x /jmatch /f file.txt /o newfile.txt
If you want, you can overwrite the original file with the result by specifying - as the output file.
jrepl "\q.*?\q" $0 /x /jmatch /f file.txt /o -
If each line in the original file is <8k, then the following pure batch script should work, and it is pretty simple:
#echo off
>newfile.txt (
for /f "delims=" %%A in (files.txt) do for %%B in (%%A) do echo %%B
)
From a batch file I want to extract the number 653456 from the following string:
C:\Users\testing\AppData\Local\Test\abc123\643456\VSALBT81_COM
The number will change, however it will always be just digits.
My current theory is to search for something that fits \alldigits\, then replace the two \s with white space, but I can’t quite get it.
Assuming the number is always the parent folder (the folder before the end):
#echo off
set "str=C:\Users\testing\AppData\Local\Test\abc123\643456\VSALBT81_COM"
for %%F in ("%str%\..") do set "number=%%~nxF"
EDIT - Code sample adapted to correct errors shown in comments
set d=C:\Users\testing\AppData\Local\Test\abc123\643456\VSALBT81_COM
for %%f in ("%d:\=" "%") do for /f %%n in ('echo %%f^|findstr /b /e /r "\"[0-9]*\""') do (
echo %%~n
)
Just precede the path with a quote, split the path, replacing each backslash with a quote a space and a quote and append a quote (so we have a list of elements to iterate), and for each part check if it is formed only by numbers
#echo off
setlocal EnableDelayedExpansion
set "string=C:\Users\testing\AppData\Local\Test\abc123\643456\VSALBT81_COM"
for /L %%d in (0,1,9) do set "string=!string:\%%d=\ %%d!"
for /F "tokens=2" %%a in ("%string%") do for /F "delims=\" %%b in ("%%a") do echo Number: [%%b]
This uses a helper batch file called repl.bat from - https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat
#echo off
set "string=C:\Users\testing\AppData\Local\Test\abc123\643456\VSALBT81_COM"
echo "%string%"|repl ".*\\([0-9]*)\\.*" "$1"
Here is how I striped numbers from a string in batch (not a file path, should be generically working for a "string")
#ECHO OFF
::set mystring=Microsoft Office 64-bit Components 2013
set mystring=Microsoft 365 Apps for enterprise - en-us
echo mystring = %mystring%
for /f "tokens=1-20 delims=abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!##$&*()-= " %%a in ("%mystring%") do (
IF %%a == 64 (
set ONum=%%b
GoTo varset
)
IF %%a == 32 (
set ONum=%%b
GoTo varset
)
set ONum=%%a
)
:varset
echo numfromalphanumstr = %numfromalphanumstr%
