Finding first difference between two files
Hi!
I'd like to know if it is possible for a command to find the first difference between two large files, output that line from both file and stop, so no need to continue after that to save some computation time.
I don't think looping through it will be efficient enough but that's the only thing i can think of...
Better: Aside from outputting the different line, it would be better if it could output the preceding line too.
Thanks!!!!!

SHAR(1) BSD General Commands Manual SHAR(1)
NAME
shar -- create a shell archive of files
SYNOPSIS
shar file ...
DESCRIPTION
shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands.
Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly).
shar is normally used for distributing files by ftp(1) or mail(1).
SEE ALSO
compress(1), mail(1), tar(1), uuencode(1)
BUGS
shar makes no provisions for special types of files or files containing magic characters.
EXAMPLES
To create a shell archive of the program ls(1) and mail it to Rick:
cd ls
shar `find . -print` | mail -s "ls source" rick
To recreate the program directory:
mkdir ls
cd ls
...
<delete header lines and examine mailed archive>
...
sh archive
HISTORY
The shar command appears in 4.4BSD.
SECURITY CONSIDERATIONS
It is easy to insert trojan horses into shar files. It is strongly recommended that all shell archive files be examined before running them
through sh(1). Archives produced using this implementation of shar may be easily examined with the command:
egrep -v '^[X#]' shar.file
