34.Os
35.Sh NAME
36.Nm shar
37.Nd create a shell archive of files
38.Sh SYNOPSIS
39.Nm
40.Ar
41.Sh DESCRIPTION
42The
43.Nm
44command writes a
45.Xr sh 1
46shell script to the standard output which will recreate the file
47hierarchy specified by the command line operands.
48Directories will be recreated and must be specified before the
49files they contain (the
50.Xr find 1
51utility does this correctly).
52.Pp
53The
54.Nm
55command is normally used for distributing files by
56.Xr ftp  1
57or
58.Xr mail  1  .
59.Sh EXAMPLES
60To create a shell archive of the program
61.Xr ls  1
62and mail it to Rick:
63.Bd -literal -offset indent
64cd ls
65shar `find . -print` \&|  mail -s "ls source" rick
66.Ed
67.Pp
68To recreate the program directory:
69.Bd -literal -offset indent
70mkdir ls
71cd ls
72\&...
73<delete header lines and examine mailed archive>
74\&...
75sh archive
76.Ed
77.Sh SEE ALSO
78.Xr compress 1 ,
79.Xr mail 1 ,
80.Xr tar 1 ,
81.Xr uuencode 1
82.Sh HISTORY
83The
84.Nm
85command appeared in
86.Bx 4.4 .
87.Sh BUGS
88The
89.Nm
90command makes no provisions for special types of files or files containing
91magic characters.
92The
93.Nm
94command cannot handle files without a newline ('\\n')
95as the last character.
96.Pp
97It is easy to insert trojan horses into
98.Nm
99files.
100It is strongly recommended that all shell archive files be examined
101before running them through
102.Xr sh  1  .
103Archives produced using this implementation of
104.Nm
105may be easily examined with the command:
106.Bd -literal -offset indent
107egrep -v '^[X#]' shar.file
