Hi All,
How do i modify the below script such that if the input is numeric, it will give the numeric digit, else it will ouput "0"
echo "xxx" | awk '/^[0-9]+$/'
Here is the script that will do for you..
#!/bin/ksh
echo "Digits as input"
read number
test=`echo "$number" | egrep "[1]+$"`
if [ "$test" ]
then
echo "Entered number is a digit"
else
echo "0"
fi
Instead of egrep you can use awk,grep or any command for searching patterns.
Thanks

0-9 âŠī¸
typeset -i x
will force $x to be a number
hi namishtiwari,
I'm using csh shell. Is there a csh version of your code ?
not sure this will work in csh
..
case $x in
*[!0-9]*|"") echo "0";;
*) echo $x;;
esac
Hi all,
I think i have some idea of converting your ksh to csh.
See below!
Thanks all for the help!!!
#!/bin/csh
echo -n "Pls input: "
set number = ($<)
test=`echo "$number" | egrep "^[0-9]+$"`
if [ "$test" ] then
echo "Entered number is a digit"
else
echo "0"
endif
