The following worked on my old server (Ubuntu)
rename -n 's/(.*)\/.*\./$1\/$1./' */*
but not on my new server (Debian).
I'm guessing the new server is using the Perl rename. How would one convert the above to work the same with Perl rename? All it was meant to do is rename files in a folder so that the name starts with the name of the parent folder (removing any name before the last dot in the original filename). Thus, include/anything.h would become include/include.h.
The rename command that is part of the util-linux package, won't work.
You need to run :
# apt install rename
If you run the following command (GNU)
$ file "$(readlink -f "$(type -p rename)")"
and you have a result that contains Perl script, ASCII text executable and not containing ELF, then this seems to be the right tool =)
If not, to make it the default (usually already the case) on Debian and derivative like Ubuntu :
# update-alternatives --set rename /usr/bin/file-rename

Get specific file with name like abc_yyyymmdd_hhmmss.csv from directory using mget.
Example files in a folder:
abc_20221202_145911.csv
abc_20221202_145921.csv
abc_20221202_145941.csv
abc_20181202_145941.csv
But, I want to ignore hhmmss part. I want to get all files with abc_20221202_*.csv
How to include * in mget.
My code below:
File=abc_
Date=20221202
Filename=$File$Date"_*".csv
// Assume I have sftp connection established and I am in directory //where files with above naming convention are present. As I can //download the file when hardcoding exact file name during testing
conn=`lftp $protocol://$user:$password#$sftp_server -p $port <<EOF>/error.log
cd $path
mget $Filename
EOF`
The script is able to find the file but not able to retrieve it from the server.
But, if I remove * and provide the entire file name abc_20221202_145941.csv it will download the file. Why is * causing issue in retrieving the file
Assuming mget actually accepts regex:
Currently your regexp is looking for files that match abc_20221202_(underscore any number of times).csv
Just add a . before the * so it matches any character after the underscore any number of times before the .csv
Like so:
Filename=$File$Date"_.*".csv
If mget doesn't actually support regex, just use wget instead:
wget -r -np -nH -A "abc_20221202_.*\.csv" --ftp-user=user --ftp-password=psd ftp://ip/*
I think the backtick symbol was causing the problem when using *. Once I removed the ` (backtick) and used below command, it worked fine.
lftp -p $port $protocol://$user:$password#$sftp_server <<EOF>/error.log
cd $path
lcd $targetPath
mget $Filename
EOF
You probably missed an underscore between File and Date. A good way to debug such problems is to enable debug (“debug” command) and command logging (set cmd:trace true)
How can I rename many files. Remove the digits at the beginning.
I have a Mac. All the files are in the same folder.
The pattern is:
1, 2 or 3 digits - any name.php
With Regular Expression, I think it would be:
\d*-(.*).php
For example:
1-marketing.php
2-3D.php
3-without.php
I want to remove the numbers and the dash at the beginning.
In the example it would be:
marketing.php
3D.php
without.php
What I have explored two ways:
Select the files > ctrl click > rename items. This is a fantastic method to change the name of files. But I think it cannot be used in this case. If I understand, it does not support Regex. Am I right?
Terminal. I am not very familiar with terminal. I tried mv 1-marketing.php marketing.php It works for 1 file, but how can I do the same for many? I am new with the terminal. If it can be done, please explain the basic.
Open the terminal app in Mac OS X and navigate to the folder containing the .php files
cd /my/path/to-php-files/
and run the below command on the command-line.
for file in *.php; do mv -v "$file" "${file#*-}"; done
The bash parameter expansion syntax ${file#*-} removes the characters before - from the beginning, so ideally 3-number-without.php becomes number-without.php
(or) use the perl rename utility not available by default in Mac OS, you can download and install it with homebrew 🍺:
brew install rename
and do
rename -n 's/^(\d+)-(.*)/$2/' *.php
The -n is just for a dry-run to see how the files are to be renamed, remove it as
rename 's/^(\d+)-(.*)/$2/' *.php
for the actual renaming.
I am trying to take a text file that contains a list of files and copy them all to a directory. Within this directory, they will have unique directory names. An example of text file the structure can be seen below:
/data/isip/data/tuh_eeg/v0.6.0/edf/001/00000003/s01_2011_11_01/a_.edf
/data/isip/data/tuh_eeg/v0.6.0/edf/001/00000003/s01_2011_11_01/a_1.edf
/data/isip/data/tuh_eeg/v0.6.0/edf/001/00000003/s02_2011_11_11/a_.edf
/data/isip/data/tuh_eeg/v0.6.0/edf/001/00000003/s02_2011_11_11/a_1.edf
/data/isip/data/tuh_eeg/v0.6.0/edf/001/00000005/s01_2009_02_13/a_.edf

I need a shell command or an EMACS macro to go through this list and copy them all to unique directories within the current working directory. The unique directory will depend on the file; for example, for the first two files, the directory would be
/001/00000003/s01_2011_11_01/
I have tried doing this using an EMACS macro, but I was not able to get it to work. A shell command or EMACs macro would work.
Something as simple as:
cat list | sed "s/^.*edf\/\(.*\)\/\(.*\)$/mkdir -p root_dir\/\1 \&\& cp \0 root_dir\/\1\/\2/" | sh
If on OSX - install gnu-sed and use gsed instead of sed. Run command without | sh to see what it'll do. Make sure to tweak root_dir, of course.
I am new to regular expressions.
I have many irregularly numbered ascii files with no extension: g000554, g000556, g000558, g000561, g000563 ... g001979 etc
I would like to type a regex at the terminal (or in a short script) to add a .dat to all of these files.
So I would like to change them to become: g000554.dat, g000556.dat, g000558.dat, g000561.dat, g000563.dat ... g001979.dat etc
p.s. Sorry I should have provided more info: by terminal I meant a mac terminal and I cannot use the 'rename' command.
I think you're using a linux system. So i provide a bash solution. It works only if your files starts with g and there is no other files in that directory except the files you want to rename.
for i in g*; do mv "$i" "$i.dat"; done
The below would add .dat extension to all the files present in the current directory,
for i in *; do mv "$i" "$i.dat"; done
I did a ctags -R on my project which is in c++, in the directory /project/ntopng. Now, when I start cscope using cscope -R and search for main.cpp, it opens up. But, when I hit ctrl-] on #include "ntop-includes.h" in main.cpp, the error message is tag not found. The header file is inside a sub-directory in /project/ntopng/include. But, ctags -R is recursive so why is it that I am getting an error? I am using Ubuntu 12.04 with the latest version of ctags and cscope. Thank You.
I have given the below answer for Ubuntu 12.04
1. Open any file with vim
2. type :echo &tags ,It will show what path vim is using for tags file.
If it is not the expected tag file path type:
:set tags=path_to_your_tag_file (ex /project/ntopng/tags)
Remember it is valid for the current session only, Now if permanent changes required there are two options.
For All users (requires root privileges) --
1. cd /etc/vim
2. vim vimrc
3. Go to end and add set tags+=tags;path_to_your_tag_file
For the individual user:
1. cd ~
2. vim .vimrc (This file may not exists in that case newly created)
3. set tags+=tags;path_to_your_tag_file
Let me know if it worked for you.
