.Sh NAME
|
|
.Nm shar
|
|
.Nd create a shell archive of files
|
|
.Sh SYNOPSIS
|
|
.Nm shar Ar
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command writes a
|
|
.Xr 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
|
|
.Xr find 1
|
|
utility does this correctly).
|
|
.Pp
|
|
The
|
|
.Nm
|
|
command is normally used for distributing files by
|
|
.Xr ftp 1
|
|
or
|
|
.Xr mail 1 .
|
|
.Sh SEE ALSO
|
|
.Xr compress 1 ,
|
|
.Xr mail 1 ,
|
|
.Xr tar 1 ,
|
|
.Xr uuencode 1
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
command makes no provisions for special types of files or files containing
|
|
magic characters.
|
|
The
|
|
.Nm
|
|
command cannot handle files without a newline ('\\n')
|
|
as the last character.
|
|
.Pp
|
|
It is easy to insert trojan horses into
|
|
.Nm
|
|
files.
|
|
It is strongly recommended that all shell archive files be examined
|
|
before running them through
|
|
.Xr sh 1 .
|
|
Archives produced using this implementation of
|
|
.Nm
|
|
may be easily examined with the command:
|
|
.Bd -literal -offset indent
|
|
egrep -v '^[X#]' shar.file
|
|
.Ed
|
|
.Sh EXAMPLES
|
|
To create a shell archive of the program
|
|
.Xr ls 1
|
|
and mail it to Rick:
|
|
.Bd -literal -offset indent
|
|
cd ls
|
|
shar `find . -print` \&| mail -s "ls source" rick
|
|
.Ed
|
|
.Pp
|
|
To recreate the program directory:
|
|
.Bd -literal -offset indent
|
|
mkdir ls
|
|
cd ls
|
|
...
|
|
<delete header lines and examine mailed archive>
|
|
...
|
|
sh archive
