I assume he he building some automated check to verify version numbers
etc, so he want to avoid having to make special cases (different
parsing) for every single software he is verifying.
You could create a wrapping perl script that is taking the "software" as
an input parameter and then according to a config file (or a hash inside
of the perl script) that will give you the answer you want.
ls.command=ls --version
ls.regexp=ls[^\d]+(\d+\.\d+\S+)\s*
gcc.command=gcc -dumpversion
gcc.regexp=^(\d+\.\d+\S+)\s*
Create a hash based on this, preform a
if($hash{$software}{'command'} =~ /$hash{$software}{'regexp'}/) {
print $1;
}
If you aren't familiar with Perl programming, I can create the script
for you, it is a quick task.
