It only gives the first file because you're telling xargs to only give it the first file. from man xargs:

Code:

       -l[max-lines]
              Synonym for the -L option.  Unlike -L, the max-lines argument is
              optional.   If  max-lines  is not specified, it defaults to one.
              The -l option is deprecated since the POSIX  standard  specifies
              -L instead.

Remove the -l and it will feed in more.

Be warned, however, that if there are enough files, xargs will be forced to call tar more than once, because it's unable to fit them all into one commandline. when this happens, tar will happily replace the archive it already created with a new one. To avoid this, you must tell tar to append (r, rather than c, option).

This doesn't work for compressed tarballs however -- you can't append to those. You must compress it later.

So:

Code:

find . -type f -exec egrep -il 'aaaa|bbbbb|ccccc' {} \; | xargs tar -rvf /tmp/$$.tar

( echo "To:  username@host"
  echo "From:  me@host"
  echo "Subject:  auto-tarball"
  echo
  gzip /tmp/$$.tar | uuencode filename.tar.gz ) | sendmail username@host 

rm -f /tmp/$$.tar

shar

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
