[GLLUG] Shell Scripting

[Melson, Paul]

Try this:

jpgz=`ls /home/darrel/*.jpg 2>/dev/null`
if [ "${jpgz}x" != "x" ]; then
  # do this if there are files
  echo "dude!  what does mine say?"
else
  # do this if no files
  echo "sweet!  what does mine say?"
fi

Hope that helps!

Hi All!

I am trying to write a shell script that will test for
the existance of a file with a specific extension.

For example:

if [ -f /home/darrel/*.jpg ]; then
     do stuff here...
fi

It works great if I have it look for a specific file,
but will not work with any type of quoting fir the *.

I've also tried the 'test' command, but it doesn't
like multiple files either.

Any suggestions or hints as to where to go from here?

Thanks,
