Why not check for the number of arguments first and then handle the cases of one or two args? $# will contain the argument count, so:<br />
<br />
if [ $# = 2 ]; then<br />
&nbsp; # two args<br />
elif [ $# =1 ]; then<br />
&nbsp; # only one arg <br />
else<br />
&nbsp; # something I'm not prepared to deal with<br />
fi<br />
<br />
should do the trick.

The following checks for the existince of one variable being passed on the command line, and exits if it isn't there:<br />
<br />
if [[ -n $1 ]]; then<br />
&nbsp; print<br />
else<br />
&nbsp; print<br />
&nbsp; print &quot;&nbsp; &nbsp;** Enter Node Name (i.e. createServerGroup.sh SpherionServerGroup) **\n&quot;<br />
&nbsp; exit 1<br />
fi<br />
<br />
How can I check for two variables being passed in the same if statment?<br />
<br />
Thanks,<br />

check for existence of 2 command line variables

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
