shcomp

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME

       shcomp - compile a shell script

SYNOPSIS

       shcomp [ options ] [infile [outfile]]

DESCRIPTION

       Unless  -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with
       the same effect as the original script.

       Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.

       If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages	that  need  to	be  translated	to
       locale specific versions for internationalization.

       If  outfile  is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from
       standard input.

OPTIONS

       [D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization.	[n noexec] Displays  warn-
       ing messages for obsolete or non-conforming constructs.	[v verbose] Displays input from infile onto standard error as it reads it.

EXIT STATUS

       0
	 Successful completion.
       >0
	 An error occurred.
