GZEXE(1)		FreeBSD	General	Commands Manual		      GZEXE(1)

NAME
     gzexe -- create auto-decompressing	executables

SYNOPSIS
     gzexe [-d]	file ...

DESCRIPTION
     The gzexe utility uses gzip(1) to compress	executables, producing exe-
     cutables that decompress on-the-fly when executed.	 This saves disk
     space, at the cost	of slower execution times.  The	original executables
     are saved by copying each of them to a file with the same name with a `~'
     suffix appended.  After verifying that the	compressed executables work as
     expected, the backup files	can be removed.

     The options are as	follows:

     -d	     Decompress	executables previously compressed by gzexe.

     The gzexe program refuses to compress non-regular or non-executable
     files, files with a setuid	or setgid bit set, files that are already com-
     pressed using gzexe or programs it	needs to perform on-the-fly decompres-
     sion: sh(1), mktemp(1), rm(1), echo(1), tail(1), gzip(1), and chmod(1).

SEE ALSO
     gzip(1)

CAVEATS
     The gzexe utility replaces	files by overwriting them with the generated
     compressed	executable.  To	be able	to do this, it is required that	the
     original files are	writable.
