Sort the items of multi-item options in profiles, the following options are supported:
|
|
private-bin, private-etc, private-lib, caps.drop, caps.keep, seccomp.drop, seccomp.drop, protocol
|
|
|
|
Usage:
|
|
$ ./sort.py /path/to/profile [ /path/to/profile2 /path/to/profile3 ... ]
|
|
Keep in mind that this will overwrite your profile(s).
|
|
|
|
Examples:
|
|
$ ./sort.py MyAwesomeProfile.profile
|
|
$ ./sort.py new_profile.profile second_new_profile.profile
|
|
$ ./sort.py ~/.config/firejail/*.{profile,inc,local}
|
|
$ sudo ./sort.py /etc/firejail/*.{profile,inc,local}
|
|
|
|
Exit-Codes:
|
|
0: No Error; No Profile Fixed.
|
|
1: Error, one or more profiles were not processed correctly.
|
|
101: No Error; One or more profile were fixed.
