How long has this disk been powered on

List all Samba user name

Copy the text from the 3rd line to the 9th line into a new file with VI

Decrypt exported android wallet keys for import into desktop client (LTC,FTC,BTC)

This one uses hex conversion to do the converting and is in shell/sed only (should probably still use the python/perl version).

By setting the UNIX95 variable in HP-UX the XPG4 mode is activated, you get new options for ps and other commands, for me the best way to use this is to create an alias named ptree in root profile: alias ptree='UNIX95=1 ps -eH'

Load another file in vim

You can then switch from a file to another with ^W^W

copy ACL of one file to another using getfacl and setfacl

Rename duplicates from MusicBrainz Picard

Renames duplicates from MusicBrainz Picard, so you get the latest copy and not a bunch of duplicates.
