Hi,

Those lines are the contents of the text file and I don’t want to change the actual directory or the file on server. I want to change the contents of the file where all file file names ending at the line should be removed. So the final file contents should look like this

cat filecontenet.txt
/usr/home/htdocs/drag-and-drop/
/usr/home//htdocs/sms/publish/pages/
/usr/home/htdocs/track/
/usr/home/htdocs/smstest/
/usr/home/htdocs/
/usr/home/htdocs/

I think rename would not help here in editing file contents.

for this question , awk really helpful with single line command

go to the current directory
ls -l | grep -v ^d | awk ‘{print $9}’ > new.txt

$9 — is the last filed which is filename only when u list with option ls -l ,
new.txt contains only the filenames which you wnated to filter out

Does the -b (byte offset) work when greping binary files? I do not get an offset returned when I grep a binary file, but I do when using a text file. I am using grep under Cygwin.

Hi,
The options mentioned in point 6 for displaying the context with A, B, & C does not seem to work on Solaris 10 with both grep & egrep

Is there a version of this grep available for Solaris?

Thank you,
Varun.
