I have 4 machines running RedHat 4.2.
I've done a 'rpm -qa | sort > machinename' on each machine to get a
sorted listing of all of the RPMs installed on each machine. Now, I'd
like to send the 4 files to some kind of script that will compare them
and show which are the same and which are different.
I'm hoping a script like this already exists, if not, I plan on
writing one in PERL then letting everyone know about it. If you have
something similar to this that I might be able to modify, let me know
before I re-invent the wheel.
example (i'm using a ';' to act as a newline to save space in the
email):
machine1: ash-0.2-8; fstool-2.5-1; gpm-1.10-8; lpr-0.30-0
machine2: bash-1.14.7-1; fstool-2.5-1; lpr-0.30-0
machine3: ash-0.2-7; fstool-2.5-1; lpr-0.30-0
machine4: ash-0.2-8; byacc-1.9-4; gpm-1.10-8
./thecoolscript machine1 machine2 machine3 machine4
then the output would be:
machine1 machine2 machine3 machine4
---------------------------------------------------------------
ash-0.2-8 ash-0.2-7 ash-0.2-8
bash-1.14.7-1
byacc-1.9-4
fstool-2.5-1 fstool-2.5-1 fstool-2.5-1
gpm-1.10-8 gpm-1.10-8
lpr-0.30-0 lpr-0.30-0 lpr-0.30-0
also, does anyone have a program/script/perl regex that will separate
the package number of a package from the package name? That
would allow me to show different versions of the same package
on the same line. (like what I did with ash above)
thanks,
mark
