gzexe
— create
auto-decompressing executables
gzexe |
[-d ] file ... |
The gzexe
utility uses
gzip(1) to compress
executables, producing executables 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
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 compressed using gzexe
, files
in /bin or /sbin, or
programs it needs to perform on-the-fly decompression:
sh(1),
basename(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.
