I need to create an “if statement” that checks to see if variables have been sent. My “if statement” must have at least two variables sent to be valid but I also need to be able to check to see if variable 3-12 have been passed. I need to execute specific functions for each additional variable passed. How do I check to see what the last variable passed is?

$# shows the number of command line variables. if [ $# > 1 ];then echo $# else echo "Not enough params" exit 0 fi

Thanks...That's what I needed I knew it was simple. Thanks again.

For the sake of accuracy, I guess we need to point out that the above solution is incorrect. That statement will never echo "Not enough params". Also, it will create an empty file named "1" because the right-angle bracket redirects output to a file. The proper test would be: if [ $# -gt 1 ]

Or in Korn/Bash/Z shell: if [[ $# > 1 ]]

Thanks WilliamRobertson. I'm sure that's what Craig intended.

Note that the [[ x > y ]] construct is not intended for numerical compares, but rather for alphanumerical compares.  For example: if [[ 5 > 450 ]] ; then    echo 'Test1 is true' else    echo 'Test1 is false' fi if [ 5 -gt 450 ] ; then    echo 'Test2 is true' else    echo 'Test2 is false' fi ./testit.sh Test1 is true Test2 is false
