echo command
 
i have written a code
Quote:
for x in $*
do
echo $x | grep "^[0-9]*$"
if [ $? -eq 0 ]
then
echo $?
fi
here in the above oode its searching for a number and displaying properly the value of $?
But problem is if the argument is a numeric one it displays the number also else its not dispalying

can any one exaplin why so nd how can i rectify that?

Please use CODE tags for code, most easily by using Advanced mode and using the # button.

What do you want the code to do?
