37.Os
38.Sh NAME
39.Nm shar
40.Nd create a shell archive of files
41.Sh SYNOPSIS
42.Nm
43.Ar
44.Sh DESCRIPTION
45The
46.Nm
47command writes a
48.Xr sh 1
49shell script to the standard output which will recreate the file
50hierarchy specified by the command line operands.
51Directories will be recreated and must be specified before the
52files they contain (the
53.Xr find 1
54utility does this correctly).
55.Pp
56The
57.Nm
58command is normally used for distributing files by
59.Xr ftp 1
60or
61.Xr mail 1 .
62.Sh SEE ALSO
63.Xr compress 1 ,
64.Xr mail 1 ,
65.Xr tar 1 ,
66.Xr uuencode 1
67.Sh BUGS
68The
69.Nm
70command makes no provisions for special types of files or files containing
71magic characters.
72The
73.Nm
74command cannot handle files without a newline ('\\n')
75as the last character.
76.Pp
77It is easy to insert trojan horses into
78.Nm
79files.
80It is strongly recommended that all shell archive files be examined
81before running them through
82.Xr sh 1 .
83Archives produced using this implementation of
84.Nm
85may be easily examined with the command:
86.Bd -literal -offset indent
87egrep -v '^[X#]' shar.file
88.Ed
89.Sh EXAMPLES
90To create a shell archive of the program
91.Xr ls 1
92and mail it to Rick:
93.Bd -literal -offset indent
94cd ls
95shar `find . -print` \&| mail -s "ls source" rick
96.Ed
97.Pp
