BASH text editing

[hammer v2]

Hi guys,
I'm making a metapackage creator script and need some help manipulating text.

I have a txt file like this...

Package: barry
Version: 1.0
Section: unknown
Priority: optional
Maintainer: Superdeb! <superdeb@superdeb.org>
Architecture: i386
Depends: ckermit_211-8ubuntu1, libsocksd_1.1.18-2.1, openbsd-inetd_0.20050402-6
Description: This is the metapackage used to install barry


But i need it to look like this;

Package: barry
Version: 1.0
Section: unknown
Priority: optional
Maintainer: Superdeb! <superdeb@superdeb.org>
Architecture: i386
Depends: ckermit, libsocksd, openbsd-inetd
Description: This is the metapackage used to install barry


Any Ideas?

Hi,

If you are sure you want to drop everything after '_' from a given string.

this code will do it


str_var=ckermit_211-8ubuntu1
echo $str_var # prints ckermit_211-8ubuntu1
echo ${str_var%%_*} # prints ckermit


I hope this helps.

regards,
Hardik
