I've asked a similiar question to this, but this time it is different, a little more restrictive....I have a variable, $varib, that should always only contain numeric characters. I need a way to echo something if the variable contains a letter, space, or some other punctuation character, ,.!>?" etc.
Previously I used: grep '[a-zA-Z]' and that can work for letters, but what about the other characters?
quick question, I am trying to run this simple equation
expr 2048 / 2.354
but get a "expr: non-numeric argument" error when ever its run. I believe it may be caused by the decimal point but I do not know how to remedy it. (3 Replies)
Hi,
How can I check numeric value in shell?
I am passing one parameter (integer) and I want to restrict any other characters except 0-9.
./script xyz 10
Here 2nd parameter (10) should be integer only.
Can anyone help on this?
