The find -exec primary's synopsis lines from the POSIX standard are:
Code:
−exec utility_name [argument . . .] ;
−exec utility_name [argument . . .] { } +

When entering the 1st form on a shell command line, you have to use \; instead of just ; because the semicolon has a special meaning to the shell. In the first form, if any argument is {}, it will be replaced by the currently matched pathname, and utility_name will be invoked with the modified argument(s). When using this form, some (but not all) find implementations will replace any occurrence of {} in an argument with the pathname; others only replace {} when those two characters are the only characters in the argument.

In the second form, the {} can only appear once and it must be the last argument before the -exec primary's terminating + operand. In this form, utility_name may be invoked with the given arguments and several matched pathnames. The number of pathnames that can be passed to the given utility will be limited by the system's setting for {ARG_MAX} (the maximum number of bytes that can be passed to a child process in its environment and argument lists). If you are processing a lot of files, only use the pathname a single time and as the last argument in the argument list, and the utility accepts multiple pathname operands, this form can be significantly more efficient.

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
