comparing strings in seperate files
Hello,
I am comparing files with for mismatches using fgrep but I've run into a problem.
fgrep -vf $file1 $file2 > mismatches.dat
file1 and file2 both contain file names on each line
file1 has filenames which are up to 92 characters long and contain the "$" char.
example file name:
A12345BBB Service ABC Test Program Sample $Performance Plan Test Document Septemper 15 2007.doc
I put quotes around the string to hand the special character but the file name is too long for the fgrep utility.
Is there another utility to search for and handle long strings with special characters?
thanks,

DIFF(1) General Commands Manual DIFF(1)
NAME
diff - print differences between two files
SYNOPSIS
diff [-c | -e | -C n] [-br]file1 file2
OPTIONS
-C n Produce output that contains n lines of context
-b Ignore white space when comparing
-c Produce output that contains three lines of context
-e Produce an ed-script to convert file1 into file2
-r Apply diff recursively to files and directories of
EXAMPLES
diff file1 file2 # Print differences between 2 files
diff -C 0 file1 file2
# Same as above
diff -C 3 file1 file2
# Output three lines of context with every
diff -c file1 file2 # Same
diff /etc /dev # Compares recursively the directories /etc and /dev
diff passwd /etc # Compares ./passwd to /etc/passwd
DESCRIPTION
the same name, when file1 and file2 are both directories" difference encountered"
Diff compares two files and generates a list of lines telling how the two files differ. Lines may not be longer than 128 characters. If
the two arguments on the command line are both directories, diff recursively steps through all subdirectories comparing files of the same
name. If a file name is found only in one directory, a diagnostic message is written to stdout. A file that is of either block special,
character special or FIFO special type, cannot be compared to any other file. On the other hand, if there is one directory and one file
given on the command line, diff tries to compare the file with the same name as file in the directory directory.
