In a korn shell script, how would I check to see if a filename exists (i.e. Jackfile) in my current directory and if so, do a set of script commands.

Here's a Korn shell script that does exactly that.

if test -r file.extension ; then
echo good;
else
echo bad;
fi;

if [ -f yourfile.txt ]
   <do something here>
else
   <do something else here>
fi


Note:  This also works with wildcards
ie. if [ -f *.txt ]

Also, spacing matters, don't leave it out!

use the IF ; THEN command ...

if [[ -f <file> ]] ; then
  echo "file found!"
else
  echo "file not found!"
fi

The problem for me, is how to do this with wildcards?

if [[ -f file*.txt ]] ; then
  echo "File found"
else
  echo "not found!"
fi

The above does not work. It actually tries to find a file with an asterisk as part of the file name - literally!
