A simple SuSe Linux user spot checks, user account info collector, bash.

Was working on user spot check on the hosts, collecting info and the
like. Posting the script here for general know-how and comment /
feedback, at the risk of being mocked in a public forum. Well here it
is, thanks in advance for comments. JB!!

echo "`uname -n` :: User Spot Checks."
# Paths norm are /usr/bin, /bin, for sed,passwd, df and so on.
# Else full paths and checks used to DIAG if missing, is the package
# installed. Bash, I did not test with other shells.
# Fur SuSe Linux, tested on Rel = 9+ 10+.
# Line Formating = One : then data, two :: then errors, host name in
the
# line.
# Why is not the last letter, thus why is why oft the last
# question we ask. "DNA"
# Why no awk, lazy, and tr,cut much smaller in loops.
