Shell scripting issue

Dewa Negara_4 — Fri, 26 Aug 2005 01:48:06 GMT

Hi All,

I have an issue on a shell scripting. I have a regular file called fileA below :

##### BEGIN M400#4 #####
/var/opt/secu/log/console
/var/spool/sockets/pwgr
/var/opt/dce/rpc/local/s-0
/var/opt/dce/rpc/local/s-3
/var/spool/cron/tmp
##### END M400#4 #####

How can I trigger the file using a shell script, so the result will be all lines between "BEGIN M400#4" and "END M400#4".

So the result should be :
/var/opt/secu/log/console
/var/spool/sockets/pwgr
/var/opt/dce/rpc/local/s-0
/var/opt/dce/rpc/local/s-3
/var/spool/cron/tmp

Pls help. High score will be given.

Thanks for your help in advance.

Best Regards,
Dewa

Try something like:

sed -e '/BEGIN M400#4,/END M400#4/p'

Hi,

There is several ways to do this,
cat | awk ' $1 !~ /###/ { print $0 }'

Thanks alot for your help.

Hi Vibhor,

I got an error message when run your script :

[root@sihp8039:/home/ap1030]
# sed -e '/BEGIN M400#4,/END M400#4/p'
sed: /BEGIN M400#4,/END M400#4/p is not a recognized function.

Hi Leif,

How can we state on the script with "BEGIN M400#4" and "END M400#4"? How the command will be?

Best Regards,
Dewa

Okay,

Just a small modification.

sed -n '/BEGIN M400#4/,/END M400#4/p'
