Subject: [PATCH] ver_linux: jfsutils.patch
Not to be critical of anyone, I believe that using 'grep' along with
'sed', and 'awk' in this kind of context as a one-off quick solution to
be run on the command line may very well be justified.
However, in a script, 'awk' or 'sed' are more than capable of doing most
of the things we may be looking to achieve by using a combination of
'grep', 'sed', and 'awk'.
The proposed implementation relies on 'sed' to perform all the text
processing required.
Tested on:
Arch Linux
