Full Discussion: How can I keep certain characters from appearing in a filename?
Operating Systems Linux How can I keep certain characters from appearing in a filename? Post 302905008 by rbatte1 on Monday 9th of June 2014 05:44:26 AM

Which command were you thinking of intercepting? Is this to be illegal for the Operating System and software too? That might have unpredictable results, and I'm not sure how you would stop redirection like this:-
Code:
echo "Hello world!" > /tmp/Greeting.$$


This is all down to your application design. If the part of your application that writes files is in shell script, then (it's not pretty, but) you could try:-
Code:
:
:
:
read filename?"What do you want to save this as?"
if [ "$filename" != "`echo $filename|tr -d "0-9"`" ]
then
   echo "Illegal filename.  No numerics allowed."
   # Take action here
fi

I'm left a little puzzled:-
  • Why are numerics a problem?
  • What have you tried so far?
  • What are your preferred coding tools?

Regards,
Robin
