NAME¶
shcomp - compile a ksh93 shell script
SYNOPSIS¶
shcomp [
options ] [
infile] [
outfile]]
ORIGIN OF THIS MAN PAGE¶
This man page was written by Christophe Martin <Schplurtz@free.fr> for the
Debian GNU/Linux system. It is based on "shcomp --man"
output.
DESCRIPTION¶
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.
OPTIONS¶
- -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.
EXIT STATUS¶
- 0
- Successful completion.
- >0
- An error occurred.
DEBIAN WARNING¶
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.
EXAMPLE¶
( echo '#! /bin/ksh93' ; shcomp myscript ) > myscript.bin &&
chmod 755 myscript.bin
./myscript.bin
