create auto-decompressing executables
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:
- Decompress executables previously compressed by
program refuses to compress
non-regular or non-executable files, files with a setuid or setgid bit set,
files that are already compressed using
or programs it needs to perform
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.
