Here's a helper script I wrote for systemctl to reduce the amount of typing you need to do to invoke common systemctl function. Put this script into /usr/bin or /usr/local/bin (in which case, you may need to add /usr/local/bin to root's PATH), then run 'sc --setup' to make the needed symlinks.
#!/bin/bash ##--------------------------------------------------------------------------- ## # # Script: 'sc' - systemctl shortener # Author: Brian Lowe # Date: December 2015 # # 'sc' implements a series of shortcuts for the 'systemctl' command (and # one for 'journalctl') via a series of symlinks in /usr/local/bin: # # Symlink Runs # sc systemctl # scs systemclt start # scr systemclt restart # sck systemctl stop ('k' = 'kill') # scl systemctl reload ('l' = reLoad) # scq systemctl status ('q' = 'query') # sct systemctl status ('t' = 'sTaTus') # scj journalctl ('scj NAME' runs 'journalctl --catalog --unit=NAME') # sch (provides help for the 'sc' command) # ##--------------------------------------------------------------------------- ## # # Setup: # 1. Put this script into /usr/local/bin # 2. Run the 'sc --setup' to set up the symlinks # ##--------------------------------------------------------------------------- ## # BUUS: This script is part of Brian's Useful Utilities Set ##--------------------------------------------------------------------------- ## PROGRAM_TO_RUN='systemctl' COMMAND=''
