UID/GID Listing?

[Kaboosh]

Dear Packagers,

I noticed the following in the specfile for kde4-config which I've been using as a guide to build a custom RPM for myself:

Code: [Select]

SYSUSERS=`cat /etc/passwd | grep "/bin/bash" |grep "[0-9][0-9][0-9]" |cut -d: -f1`
SYSUSERS=${SYSUSERS/named/}
for idx in $SYSUSERS
 do INP1= cp -af /etc/skel/.local/* /home/$idx/.local; done

Is there some way (in bash which RPM uses for scripting) to determine which UIDs/GIDs are in use on the system without directly accessing /etc/{passwd,group}?  PCLinuxOS offers alternate authentication mechanisms out of the box and I think this approach will break under a different configuration...
