Check for number of arguments in bash

bash args
An easier way would be via parameter substitution:
: ${1?"Usage: $0 ARGUMENT"}If parameter set, use it, else print error message.
Your check for expected Bash script Args
Sandip,
your check doesn't seem to allow a * wildcard to pass the check as an argument - it simply seems not to be counted. Why is that? My script must be able to accept this.
Any ideas, or a possible fix?
Cheers,
J.
bash globbing
That is due to bash globbing.
Try prefixing the * with \ like \* or,
`set -f` to disable globbing and then run the script.
