I'm trying to use plink on winXP to connect to a linux server and execute a command. Here's the command line I'm running:
plink some_profile cd "$(echo 'T:\somedir\somesubdir with space in it\' | sed 's_\\_/_g' | sed 's_T:_/media/drive1_g')";unrar x 'somefile.rar'
If I execute the command portion of this (start with the cd) on the linux box directly it works perfectly. But when I run it through plink, it fails with the following error:
bash: line 0: cd: /media/drive1/somedir/somesubdir: No such file or directory
I think I'm not quoting the command correctly when going through plink so it's not transferring the quotes needed to handle the spaces in the directories. Any ideas on how this should be quoted so that it works?
In case you're wondering why I'm even doing this, it's basically a script I'm running on Directory Opus where I can unrar the file I currently have highlighted (a samba mount). The directory and filename are passed to the script which will the unrar that file on my remote box.
Thanks!
EDIT: Problem solved thanks to the response from Mikel. Here is the line that works now in case anyone else comes across this later...
plink some_profile cd \"$(echo 'T:\somedir\somesubdir with space in it\' | sed 's_\\_/_g' | sed 's_T:_/media/drive1_g')\";unrar x 'somefile.rar'
You need to add another level of quotes, e.g.
plink some_profile cd "\"$(echo 'T:\somedir\somesubdir with space in it\' | sed 's_\\_/_g' | sed 's_T:_/media/drive1_g')\"";unrar x 'somefile.rar'
This is because you need one level of quotes on the Windows side, and one level of quotes on the Linux side.

sed -i s/CUSTOMER_UNIT=".*"/CUSTOMER_UNIT="Test" core/src/main/java/com/appname/core/AppConstants.kt
I am running this sed command as a result I get this
sed: ore/src/main/java/com/appname/core/AppConstants.kt: No such file or directory
It remove the first letter of core -> ore
but if I just run command find ore/src/main/java/com/appname/core/AppConstants.kt it this file exists
I am not sure if you are trying to have the results = core or ore
but when i replicate I am able to get core. One thing I noticed is in your example you are missing the terminating / for your sed command after "Test"
sed -i s/CUSTOMER_UNIT=".*"/CUSTOMER_UNIT="Test"/ core/src/main/java/com/appname/core/AppConstants.kt
sed: can't read core/src/main/java/com/appname/core/AppConstants.kt: No such file or directory
if you are trying to cut the C from core and you can manually validate the path exists I would be sure that you have proper permissions
The command should be enclosed in quotes and be ended with "/".
sed -i 's/CUSTOMER_UNIT=".*"/CUSTOMER_UNIT="Test"/' core/src/main/java/com/appname/core/AppConstants.kt
I would like to delete filenames from a textfile to have as output only the folder.
Example:
Creature\FrostwolfPup\FrostWolfPup_Shadow.m2
Creature\FrostwolfPup\FrostWolfPup_Fire.m2
To
Creature\FrostwolfPup\
To match only the Filenames i use [^\\]*$
Now i put it together with sed while /d should delete it
D:\filetype\core\sed.exe -n -e "/^[^\\]*$/d" D:\filetype\listfile\archive\tmp\all.txt > D:\filetype\module\model_bruteforce\tmp\folders_tmp1.txt
But instead of a textfile with my folders i got only a empty textfile as output, and so something must be wrong.
Tested on linux, not cygwin
sed -r 's/[^\\]*$//g' /path/to/original/file > /path/to/new/file
Try:
sed.exe -e "s/[^\\]*$//" path/to/folders.txt
The command s/[^\\]*$// asks sed to remove everything after the last \ on a line to the end of the line.
Caveat: since I don't have a windows machine handy for testing, I am unsure if the backslashes need to be doubled as shown above.
Discussion
-n tells sed not print anything unless we explicitly ask it to. The following command never asks sed to print:
sed.exe -n -e "/^[^\\]*$/d"
Consequently, it produces no output.
I am trying to remove the last newline added to the file using bash script.
I have got this -
truncate -s $(($(stat -c '%s' foo.txt)-1)) foo.txt
here foo.txt the file name.
but I want to parametrize the file name, I will pas the file name to the script and it should this remove the newline at last from that file.
Request your help on this. I do not have linux in my machine and tried using cygwin but it is giving error while running the script.
Thanks
To remove last line if it is newline use this sedL
sed -i.bak '/^[[:blank:]]*$/{$d;}' foo.txt
I have a directory full of files with one extension (.txt in this case) that I want to automatically convert to another extension (.md).
Is there an easy terminal one-liner I can use to convert all of the files in this directory to a different file extension?
Or do I need to write a script with a regular expression?
You could use something like this:
for old in *.txt; do mv $old `basename $old .txt`.md; done
Make a copy first!
Alternatively, you could install the ren (rename) utility
brew install ren
ren '*.txt' '#1.md'
If you want to rename files with prefix or suffix in file names
ren 'prefix_*.txt' 'prefix_#1.md'
Terminal is not necessary for this... Just highlight all of the files you want to rename. Right click and select "Rename ## items" and just type ".txt" into to the "Find:" box and ".md" into the "Replace with:" box.
The preferred Unix way to do this (yes, OS X is based on Unix) is:
ls | sed 's/^\(.*\)\.txt$/mv "\1.txt" "\1.md"/' | sh
Why looping with for if ls by design loops through the whole list of filenames? You've got pipes, use them. You can create/modify not only output using commands, but also commands (right, that is commands created by a command, which is what Brian Kernighan, one of the inventors of Unix, liked most on Unix), so let's take a look what the ls and the sed produces by removing the pipe to sh:
$ ls | sed 's/^\(.*\)\.txt$/mv "\1.txt" "\1.md"/'
mv "firstfile.txt" "firstfile.md"
mv "second file.txt" "second file.md"
$
As you can see, it is not only an one-liner, but a complete script, which furthermore works by creating another script as output. So let's just feed the script produced by the one-liner script to sh, which is the script interpreter of OS X. Of course it works even for filenames with spaces in it.
BTW: Every time you type something in Terminal you create a script, even if it is only a single command with one word like ls or date etc. Everything running in a Unix shell is always a script/program, which is just some ASCII-based stream (in this case an instruction stream opposed to a data stream).
To see the actual commands being executed by sh, just add an -x option after sh, which turns on debugging output in the shell, so you will see every mv command being executed with the actual arguments passed by the sed editor script (yeah, another script inside the script :-) ).
However, if you like complexity, you can even use awk and if you like to install other programs to just do basic work, there is ren. I know even people who would prefer to write a 50-lines or so perl script for this simple every-day task.
Maybe it's easier in finder to rename files, but if connected remotely to a Mac (e.g. via ssh), using finder is not possible at all. That's why cmd line still is very useful.
Based on the selected and most accurate answer above, here's a bash function for reusability:
function change_all_extensions() {
for old in *."$1"; do mv $old `basename $old ."$1"`."$2"; done
}
Usage:
$ change_all_extensions txt md
(I couldn't figure out how to get clean code formatting in a comment on that answer.)
No need to write a script for it just hit this command
find ./ -name "*.txt" | xargs -I '{}' basename '{}' | sed 's/\.txt//' | xargs -I '{}' mv '{}.txt' '{}.md'
You do not need a terminal for this one; here is a sample demonstration in MacOS Big Sur.
Select all the files, right-click and select "rename..."
Add the existing file extension in "Find" and the extension you want to replace with "Replace with".
And done!
I had a similar problem where files were named .gifx.gif at the end and this worked in OS X to remove the last .gif:
for old in *.gifx.gif; do
mv $(echo "$old") $(echo "$old" | sed 's/x.gif//');
done
cd $YOUR_DIR
ls *.txt > abc
mkdir target // say i want to move it to another directory target in this case
while read line
do
file=$(echo $line |awk -F. '{ print $1 }')
cp $line target/$file.md // depends if u want to move(mv) or copy(cp)
done < abc
list=ls
for file in $list
do
newf=echo $file|cut -f1 -d'.'
echo "The newf is $newf"
mv $file $newf.jpg
done
How can I convert a Windows dir path (say c:/libs/Qt-static) to the correct POSIX dir path (/c/libs/Qt-static) by means of standard msys features? And vice versa?
Cygwin, Git Bash, and MSYS2 have a readymade utility called cygpath.exe just for doing that.
Output type options:
-d, --dos print DOS (short) form of NAMEs (C:\PROGRA~1\)
-m, --mixed like --windows, but with regular slashes (C:/WINNT)
-M, --mode report on mode of file (binmode or textmode)
-u, --unix (default) print Unix form of NAMEs (/cygdrive/c/winnt)
-w, --windows print Windows form of NAMEs (C:\WINNT)
-t, --type TYPE print TYPE form: 'dos', 'mixed', 'unix', or 'windows'
I don't know msys, but a quick google search showed me that it includes the sed utility. So, assuming it works similar in msys than it does on native Linux, here's one way how to do it:
From Windows to POSIX
You'll have to replace all backslashes with slashes, remove the first colon after the drive letter, and add a slash at the beginning:
echo "/$pth" | sed 's/\\/\//g' | sed 's/://'
or, as noted by xaizek,
echo "/$pth" | sed -e 's/\\/\//g' -e 's/://'
From POSIX to Windows
You'll have to add a semi-colon, remove the first slash and replace all slashes with backslashes:
echo "$pth" | sed 's/^\///' | sed 's/\//\\/g' | sed 's/^./\0:/'
or more efficiently,
echo "$pth" | sed -e 's/^\///' -e 's/\//\\/g' -e 's/^./\0:/'
where $pth is a variable storing the Windows or POSIX path, respectively.
Just use cygpath:
$ cygpath -w "/c/foo/bar"
-> C:\foo\bar
$ cygpath -u "C:\foo\bar"
-> /c/foo/bar
You may wonder: "Do I have cygpath installed?" Well,
If you're using the git-bash shell, then yes.
If you're in cygwin or MSYS2, then yes.
If you're in another shell, but you have installed git-bash before, then cygpath can be found at git-bash-install-folder\usr\bin\cygpath.exe.
Else: maybe not, but I'm sure you can find a way to installed it.
The "correct" way in MSYS is:
$ MSYS_NO_PATHCONV=1 taskkill /F /T /IM ssh-agent.exe
This avoids having to manually translate slashes. It simply de-activates the path conversion.
Here is my implementation (tested on git bash).
From POSIX to Windows
sed '
\,/$, !s,$,/,
\,^/, s,/,:/,2
s,^/,,
s,/,\\,g
' <<< "$#"
Works for:
/c/git
relative/dir
c:/git
~
.
..
/c
/c/
./relative/dir
/sd0/some/dir/
except
/
<path with space>
Explanation:
\,^/, s,/,:/,2 (converts /drive/dir/ to /drive:/dir/) is the heart of it and inserts : before the 2nd /. I use , for delim instead of / for readability. If starting with / (\,^/,), then replace / with :/ for the 2nd occurrence. I do not want to assume drive letter length of 1 so this works for /sd0/some/dir.
s,^/,, removes the leading / and s,/,\\,g converts all / to \.
\,/$, !s,$,/, is to handle the corner case of /c and ensure 2nd / (/c/) for the next command to work.
Note:
If here string <<< does not work in your shell then you can echo and pipe as
echo "$#" | sed ...
Errata
Here e script
just FYI - at least for my git version 2.26.2.windows.1
e.g. if I have a path like C:\dev\work_setup\msk, I can go directly to Git Bash and type
cd "C:\dev\work_setup\msk"
this will result in current folder being changed to /c/dev/work_setup/msk - so this type of conversion seems to be done automatically, as long as I put the Windows path inside double quotes. Unfortunately I don't have references to original documentation that would back that up.
My solution works with a list of folders/files and it's done in 2 steps.
Suppose you would like to replace a path from D:\example to /example for a list of file where this Windows path has been repetead.
The first step it changes the backlashes into slashes
grep -lr "D:\\\\example" /parent-folder | xargs -d'\n' sed -i 's+\\+\/+g'
Note that parent-folder could be root (/) or whatever you like and -d'\n' parameter is necessary if you have filenames or folder names with white spaces.
Second step it substitutes the D:/example into /example:
grep -lr "D:/example" /parent-folder | xargs -d'\n' sed -i 's+D:+/example+g'
I wanted to share this solution since it tooks me some time to make this 2 lines but it has been really helpfull job (I'm migrating a Windows App to a Linux Server with tons of Windows paths inside').
The answer of #hello_earth is misleading, due to Windows path must be double backslashed like:
cd "e:\\dir\\subdir\\path"
otherwise the shell will find escape-sequences.
