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 EXAMPLES
63To create a shell archive of the program
64.Xr ls 1
65and mail it to Rick:
66.Bd -literal -offset indent
67cd ls
68shar `find . -print` \&| mail -s "ls source" rick
69.Ed
70.Pp
71To recreate the program directory:
72.Bd -literal -offset indent
73mkdir ls
74cd ls
75\&...
76<delete header lines and examine mailed archive>
77\&...
78sh archive
79.Ed
80.Sh SEE ALSO
81.Xr compress 1 ,
82.Xr mail 1 ,
83.Xr tar 1 ,
84.Xr uuencode 1
85.Sh HISTORY
86The
87.Nm
88command appeared in
89.Bx 4.4 .
90.Sh BUGS
91The
92.Nm
93command makes no provisions for special types of files or files containing
94magic characters.
95The
96.Nm
97command cannot handle files without a newline ('\\n')
98as the last character.
99.Pp
100It is easy to insert trojan horses into
101.Nm
102files.
103It is strongly recommended that all shell archive files be examined
104before running them through
105.Xr sh 1 .
106Archives produced using this implementation of
107.Nm
108may be easily examined with the command:
109.Bd -literal -offset indent
110egrep -v '^[X#]' shar.file
