.Dd January 31, 2019 .Dt SHAR 1 .Os .Sh NAME .Nm shar .Nd create a shell archive of files .Sh SYNOPSIS .Nm .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).
p The .Nm command is normally used for distributing files by .Xr ftp 1 or .Xr mail 1 . .Sh EXAMPLES To create a shell archive of the program .Xr ls 1 and mail it to Rick: d -literal -offset indent cd ls shar `find . -print` | mail -s "ls source" rick .Ed
p To recreate the program directory: d -literal -offset indent mkdir ls cd ls ... <delete header lines and examine mailed archive> ... sh archive .Ed .Sh SEE ALSO .Xr compress 1 , .Xr mail 1 , .Xr tar 1 , .Xr uuencode 1 .Sh HISTORY The .Nm command appeared in x 4.4 . .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.
p 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: d -literal -offset indent egrep -av '^[X#]' shar.file .Ed
