uname is sufficient for shell commands like df and ps.
For inventory etc. you want uname -sm
The case statement can be used like this:
Code:
#!/bin/sh
os=`uname -s`
model=`uname -m`
case "$os $model" in
"SunOS sun4u") echo "Solaris on SPARC";;
"SunOS i86pc") echo "Solaris on x86";;
"HP-UX 9000/800") echo "HP-UX on PA-RISC";;
"HP-UX ia64") echo "HP-UX on Itanium";;
"Linux x86_64") echo "Linux on x86, 64bit";;
"Linux i686") echo "Linux on x86, 32bit";;
AIX*) echo "AIX on $model";;
FreeBSD*) echo "FreeBSD on $model";;
*) echo "$os on $model";;
esac

ps -ef works on all operating systems but BSD. BSD needs ps auxw. Linux takes both.
