Shell Programming and Scripting

Hi All,

this small script is written to recognize user input character.. it is in small case .. upeer case or is a number... but when i input first capital letter say A.. it always gives small character.... what is the problem.

#!/bin/bash
echo "Enter the character"
read a
case $a in
[a-z]) echo "Small case" ;;
[A-Z]) echo "upper case" ;;
[0-9]) echo "number" ;;
?) echo "special symbol" ;;
*) echo "not recorganized" ;;
esac

I cannot reproduce your problem...

Code:

$ cat basher
#!/usr/local/bin/bash
echo "Enter the character"
read a
case $a in
[a-z]) echo "Small case" ;;
[A-Z]) echo "upper case" ;;
[0-9]) echo "number" ;;
?) echo "special symbol" ;;
*) echo "not recorganized" ;;
esac
$ ./basher
Enter the character
A
upper case
$

Work fine here too...

sh-3.2$ testing.txt
Enter the character
A
upper case
sh-3.2$ testing.txt
Enter the character
a
Small case
sh-3.2$ testing.txt
Enter the character
3
number
sh-3.2$
