make uppercase
If in a script I am taking an input (R201) for example and assigning it to a variable, how would I change the R to uppercase if it was keyed in as r201? I can't seem to get it to work with toupper

Using typeset
Krikm,
You can use the typeset options.The following script is an attempt to solve the problem.

Code:
#!/bin/ksh
typeset -u input
echo "Please Enter the input value:\c"
read input
echo "You Entered : $input"

Thanks

That works like a charm...I had never seen that before.

Code:
# var=r201
# new=$(echo $var|awk -F "" 'BEGIN{OFS=""}{ $1=toupper($1)}1')
# echo $new
R201

the other option would be to use the tr command

Code:
$ echo r201 | tr '[a-z]' '[A-Z]'
R201
