Splunk_TA_nix on HP-UX: ps: illegal option -- o

[mikelanghorst]

Recently started installing the *Nix TA on our HP-UX hosts, and noticed that uptime.sh fails, even though the if statement within is looking for HP-UX.

From uptime.sh:
# This should work for any POSIX-compliant system, but in case it doesn't
# we have left the individual OS names here to be broken out later on.
if [ "x$KERNEL" = "xLinux" -o "x$KERNEL" = "xSunOS" -o "x$KERNEL" = "xAIX" -o "x$KERNEL" = "xHP-UX" -o "x$KERNEL" = "xDarwin" -o "x$KERNEL" = "xFreeBSD" ] ; then
assertHaveCommand date
assertHaveCommand ps
CMD='eval date; LC_ALL=POSIX ps -o etime= -p 1'
....

When I attempt to run:
root@blah#./uptime.sh
ps: illegal option -- o
usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup] [-Z psetidlist]

Finally circled back to this and found the issue. HP-UX needs "UNIX95=1" set to use the -o switch for ps. It's using ps in this script, to get the SystemUpTime field.

I've just updated my copy of the script with the following snippet.
- #Setting UNIX95 for HP-UX
- if [ "x$KERNEL" = "xHP-UX" ]; then
- export UNIX95=1
- fi

[mikelanghorst]

it was already set in the ps.sh script, which is how I stumbled across it. I tried to copy/paste the CMD from ps.sh and got that same error.

Thanks Mike! The UNIX95 variable is certainly one of the most interesting things I've discovered through authoring some of this add-on: http://jreypo.wordpress.com/2010/02/01/unix95-and-ps-command/

Thanks Mike, I filed NIX-596 for this issue.
