Subject[PATCH] ver_linux: ppp.patch
The current implementation uses both 'grep' and 'awk' for text processing
here, which may be alright as a quick solution to be run on the command
line. While in a script, 'sed' or 'awk' would be a better choice. On
top of that, the current implementation expects the version number to be
found in field 3 as seen by 'awk'. Should the output format be different,
this approach would no longer be reliable.

The proposed implementation uses 'sed' as a more flexible tool to handle
varying output formats.


Tested on:
Arch Linux
