GZEXE(1)                  BSD 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 executables that decompress on-the-fly on-thefly
     fly when executed.  This saves disk space, at the cost of slower execution times.  The original exe-cutables executables
     cutables 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 set-gid setgid
     gid bit set, files that are already compressed using gzexe or programs it needs to perform on-the-fly
     decompression: 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.
