Pattern substitution

Chern Jian Leaw — Sat, 11 May 2002 08:23:30 GMT

I would like to remove the following patterns i.e find: and also :Permission denied from my file, f1, and maintain only the second field i.e /fs36/nwd/f1 and /fs36/nwd/f1/audio. The file f1 has the following format:

find: /fs36/nwd/f1 :Permission denied
find: /fs36/nwd/f1/audio :Permission denied

How do I write a csh script to do that? What is the single command utility does the job?

Thanks.

Thanks. I tried the following on file f1, but it did not work
%s/find:/ /g
%s/:Permission denied/ /g

Hi

From the command line

sed s/find://g f1
sed s/:Permission denied//g f1

I'll put in a script as well

Hi

After using vi to edit the file

%s/find:/ /g

Your method also works

HI

please ignore my last response I misread the question the grep -v will remove the full line from the file.

cat f1 | cut -f2 > newfile
