Hi,
OS: Unix, linux, hp-unix (all unix flavours)

Iam trying to change some string values, special characters or otherwise in a file. As of now, i go using vi <filename>, open the file and do the edit manually and save it.
Is it possible to write a shell script so that i just run the script which inturn opens this particular file and changes all the stuff needed and save the same.
The string values will be in any line in the file.

In file change.sh (I have to change three things as mentioned below)

** change database ****

Try...

perl -pi -e '
s|connect to F750PAX|connect to F750PBX|g;
s|../jre/lpp/java/J1.4.2/bin/java com.telex.pt.environment.agent.Agent $1|/usr/lpp/java/IBM/J1.4.2/bin/java com.telex.pt.environment.agent.Agent $1|g;
s|hubURL=http://clist.check.com:80/PSEMHUB/hub|hubURL=http://register.lagoon.com:8001/PSEMHUB/hub|g' filename

Oh. Thanks. Its as simple as that, which i dont know.
BTW, i understand you have used perl. I dont think i have perl installed in my box. How do i check if perl is installed?
Iam yet to know 'perl'.
Can i put this (your code) into my shell script and run the same?

thanks once again for your response.

Thanks.
I found out from another thread "how to check that perl is installed on the system". That's perl -v
and checking my box, i do see perl is installed.

Thanks once again. I put it in a shell script and its working perfectly.
