There is no "universal" command that is guaranteed to work on *ALL* UNIX/Linux flavors.
RHEL-based have rpm, Solaris has pkginfo, Debian-based have dpkg, I don't know about Arch but you get the point.
A simpler generic approach would be to find / -type f -name "sshd" but it's not bulletproof.
Another option would be to match your commands against /etc/*release but -again- it's not bulletproof either; I've seen several sysadmins modify this file in order to trick the system so that they can install unsupported applications (Oracle for example). Something like this:
The above code for instance won't work on a Linux minimal installation as it relies on "egrep" command.
It would be easier if you were looking for running processes; ps almost works the same in all Unix/Linux (either ps -A or ps -e should do).
rshstatus=`rsh -n lilo /db/p2/oracle/names9208/restart_names.sh`
if $rshstatus <>0 then
errstatus=1
mailx -s "xirsol8dr" ordba@xxx.com >> $log_dr
else if errstatus=0
echo "status to xirsol8dr successful"
can anyone provide if this is t he correct way to do this or is there a better way? (1 Reply)

uuidd
UUIDD(8) System Administration UUIDD(8)NAME
uuidd - UUID generation daemon
SYNOPSIS
uuidd [options]
DESCRIPTION
The uuidd daemon is used by the UUID library to generate universally unique identifiers (UUIDs), especially time-based UUIDs, in a secure
and guaranteed-unique fashion, even in the face of large numbers of threads running on different CPUs trying to grab UUIDs.
OPTIONS -d Run uuidd in debugging mode. This prevents uuidd from running as a daemon.
-h, --help
Display help screen and exit.
-k, --kill
If currently a uuidd daemon is running, kill it.
-n, --uuids number
When issuing a test request to a running uuidd, request a bulk response of number UUIDs.
-p, --pid path
Specify the pathname where the pid file should be written. By default, the pid file is written to /var/run/uuidd/uuidd.pid.
-q Suppress some failure messages.
-r, --random
Test uuidd by trying to connect to a running uuidd daemon and request it to return a random-based UUID.
-s, --socket path
Specify the pathname used for the unix-domain socket used by uuidd. By default, the pathname used is /var/run/uuidd/request. This
is primarily for debugging purposes, since the pathname is hard-coded in the libuuid library.
-T, --timeout timeout
Specify a timeout for uuidd. If specified, then uuidd will exit after timeout seconds of inactivity.
-t, --time
Test uuidd by trying to connect to a running uuidd daemon and request it to return a time-based UUID.
-V, --version
Output version information and exit.
EXAMPLE
Start up a daemon, print 42 random keys, and then stop the daemon.
uuidd -p /tmp/uuidd.pid -s /tmp/uuidd.socket
uuidd -d -r -n 42 -s /tmp/uuidd.socket
uuidd -d -k -s /tmp/uuidd.socket
AUTHOR
The uuidd daemon was written by Theodore Ts'o <tytso@mit.edu>.
AVAILABILITY
The uuidd daemon is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
