So sorry -- I was assuming that you knew how to use find.

When I put something in brackets, that is an optional thing. Are all the files in a single directory? If so, you would use "-maxdepth 1" so that find won't go returning all the files contained in the starting directory.

Here is what I am guessing: You a Mac, you used an unerase tool that did not recover the names, and all the files are in a single directory in the form of:
Code:
Illustrator 9-10-04003
Illustrator 9-10-04004
Illustrator 9-10-04005
Illustrator 9-10-04006

If so, the loop might look like this:

Code:
#!/bin/bash

#hacker_renamer

cd [PUT THE DIRECTORY HERE]

find . -type f -maxdepth 1 -print0 | while read -d $'\0' file
do
  head -10 "$file"   # use the loop variable for the name

  newnam=`head -10 "$file" | grep "%%Title" | cut -d" " -f2"`

  printf "mv -n %s %s\n" "$file" "$newnam"
done

Try and inspect that the individual "mv" statements are good.

Once you are satisfied, pipe the output back to shell like so:

./hacker_renamer | /bin/bash

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
