I'm only being pedantic because you are building a useful resource.

Code:
#!/bin/ksh
[ $# -ne 2 ] && echo "Usage ${0} input1 input2 " && exit 1;
echo $2 $1

Personally I might use "&&" to test the success of a command when writing a dependent cron, but rarely in scripts.
However in Oracle scripting the semicolon is critical.
ohh
thanks methyl Smilie
