shcomp − compile a ksh93 shell script
shcomp [ options ] [infile] [outfile]]
This man page was written by Christophe Martin <Schplurtz@free.fr> for the Debian GNU/Linux system. It is based on "shcomp −−man" output.
Unless −D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh93 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.
−D, −−dictionary
Generate a list of strings that need to be placed in a message catalog for internationalization.
−n, −−noexec
Displays warning messages for obsolete or non-conforming constructs.
−v, −−verbose
Displays input from infile onto standard error as it reads it.
|
−−man |
Displays this man page on standard error and exits. | ||
|
−−help |
Shows a short help message and exits. |
|
0 |
Successful completion. |

>0 |
An error occurred. |
On a Debian GNU/Linux system, more than one package may provide ksh. the output of shcomp can only be used by ksh93. Any other ksh will be unable to run the compiled script.
