GZEXE(1)                  BSD General Commands Manual                 GZEXE(1)

     gzexe -- create auto-decompressing executables

     gzexe [-d] file ...

     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).


     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.
