typeset not working

[XST1]

I cant get typeset working for some reason.... heres my script:

Code: Select all

#!/bin/bash

for parameterList in $*
do
	typeset -u parameterList
	echo $parameterList
done

heres the warning I get:

typeset: usage: typeset [-afFirtx] [-p] name[=value] ...

-u should be an argument of typeset (-u is used to turn a string to uppercase and -l should turn a string to lowercase)

You appear to be mistaken (based on the warning bash gave you, and bash(1)). As for an alternative, tr can be used to change case:

Code: Select all

#!/bin/bash

upper () {
  echo "$*" | tr [:lower:] [:upper:]
}

for param in "$@"
do
  echo "$(upper $param)"
done

Hope this helps,
