NAME

     shc - Generic shell script compiler

SYNOPSIS

     shc [ -e date ] [ -m addr ] [ -i iopt ] [ -x cmnd ][ -l lopt ] [ -ACDhTv ] -f script

DESCRIPTION

     shc creates a stripped  binary  executable  version  of  thescript specified with -f on the command line.The binary version will get a .x extension appended and willusually  be  a  bit  larger  in size than the original asciicode. Generated C source code is saved in a  file  with  theextension .x.cIf you supply an expiration date with the -e option the com-piled  binary  will  refuse to run after the date specified.The message "Please contact your provider" will be displayedinstead.  This message can be changed with the -m option.You can compile any kind of shell script, but  you  need  tosupply valid -i, -x and -l options.The compiled binary will still be  dependent  on  the  shellspecified  in  the  first  line  of  the  shell  code  (i.e.#!/bin/sh), thus shc does not create completely  independentbinaries.shc itself is not a compiler such as cc, it  rather  encodesand encrypts a shell script and generates C source code withthe added expiration capability. It  then  uses  the  systemcompiler  to compile a stripped binary which behaves exactlylike the  original  script.  Upon  execution,  the  compiledbinary  will  decrypt and execute the code with the shell -coption.  Unfortunatelly, it will  not  give  you  any  speedimprovement as a real C program would.shc's main purpose is to protect  your  shell  scripts  frommodification  or  inspection.  You can use it if you wish todistribute your scripts but don't want  them  to  be  easilyreadable by other people.

OPTIONS

     The command line options are:-e dateExpiration date in dd/mm/yyyy format [none]-m messagemessage to display  upon  expiration  ["Please  contactyour provider"]-f script_nameFile name of the script to compile-i inline_optionInline option for the shell interpreter i.e: -e-x comandeXec    command,    as    a    printf    format    i.e:exec(\\'%s\\',@ARGV);-l last_optionLast shell option i.e: ---r   Relax security. Make  a  redistributable  binary  whichexecutes  on different systems running the same operat-ing system.-v   Verbose compilation-D   Switch on debug exec calls-T   Allow binary to be  traceable  (using  strace,  ptrace,truss, etc.)-C   Display license and exit-A   Display abstract and exit-h   Display help and exit

ENVIRONMENT VARIABLES

     CC   C compiler command [cc]CFLAGSC compiler flags [none]

EXAMPLES

     Compile a script which can be run on other systems with  thetrace option enabled:example% shc -v -r -T -f myscript
