Do you mean the input itself "\" ?
Then use \\

Aju,Anbu,
Thanks for the replies.
Anbu,
For eg: I executed the script as follows by preceeding with \ for input <
Code:
[sabraham@secmstqatmp]# ./shellpgm37.sh \>

Now i get the correct value.

But if i try like
Code:
./shellpgm37.sh  \$%#&*

i get error as

Code:
./shellpgm37.sh  \$%#&*
[1]     19373
ksh: 0:  not found
[sabraham@secmstqatmp]# Error

Is there any other way to do this.

Thanks,
Sumesh

If you have Python installed:
Code:
#!/usr/bin/ksh
input=`echo $1 | /usr/bin/python -c "print raw_input().isdigit()"`
if [ $input == "True" ]; then
   echo "Input is a digit"
fi
....
...
..

./shellpgm37.sh '$%#&*'
use single code while entring special characters as args
