SHELL(1) UNIX Programmer's Manual SHELL(1)
NAME
shell - Interpreter for shell archives
SYNOPSIS
shell [ file ]
DESCRIPTION
This program interprets enough UNIX shell syntax, and com-
mand usage, to enable it to unpack many different types of
UNIX shell archives, or ``shar's.'' It is primarily intended
to be used on non-UNIX systems that need to unpack such
archives.
Shell does not check for security holes, and will blithely
execute commands like
cp /dev/null /etc/passwd
which, if executed by the super-user, can be disastrous.
The shell parser is line-based, where lines are then split
into tokens; it is not a true token-based parser. In gen-
eral, it is best if all sh keywords that can appear alone on
a line do so, and that compound commands (i.e., using a
semi-colon) be avoided. For more details on the syntax, see
the source (sorry...).
BUGS
It is probably easier to write a true portable replacement
for /bin/sh than it is to write something which understands
all shar formats.
