Question

I have a inputfile with template as shown below. I want to change the Version: using sed.

    Package: somename
    Priority: extra
    Section: checkinstall
    Maintainer: [e-mail]
    Architecture: i386
    Version: 3.1.0.2-1
    Depends:
    Provides: somename
    Description: some description

Currently I am getting the current version using grep -m 1 Version inputfile | sed 's/[:_#a-zA-Z\s"]*//g' and I am trying to replace the current version with sed 's/3.1.0.2-1/3.1.0.2/' inputfile

However this does not seem to work, but when I try it in command line using echo it works.
echo 'Version: 3.0.9.1' | sed 's/3.0.9.1/3.2.9.2/'

Output: Version: 3.2.9.2

Any help on how I can accomplish this would be appreciated. Preferably I would like to change the version without getting the current version in the file.

Thanks In Advance

You don’t need the grep.

sed -i '/Version/s/3\.1\.0\.2-1/3.1.0.2/' <files>
