To Whom It May Concern

This is what Radicchio loves so much:

$ # Git.
$ git status && git fetch -p && git branch -a && git tag -l && git pull && git status

The second one is a combination of find and grep:

$ # Find and print line(s) of text, based on a specified regex pattern.
$ find . -type f -print0 | xargs -0 grep '<regex>'

The third one is a combination of grep and sed (or perl, where applicable):

$ # Find a text, based on a specified regex pattern, then pass corresponding filenames to Sed (or Perl) for replacing that text with another one.
$ grep -Rl '<regex_to_replace>' | xargs sed   -i -e 's/<regex_to_replace>/<regex-replacer>/g'
$ grep -Rl '<regex_to_replace>' | xargs perl -pi -e 's/<regex_to_replace>/<regex-replacer>/g'

The fourth one is a one-time procedure of logging into a VM box or any other remote host, using SSH public key authentication:

$ # Run SSH agent in the background and add a private key.
$ eval `ssh-agent -s` && ssh-add ~/.ssh/id_rsa
$ # Log into a running VM box by means of SSH client.
$ ssh -C <vmusername>@<vmhostname>

The fifth one is a series of requests for getting statuses of power supply sensors on a laptop in any modern Linux distro like Arch Linux or Ubuntu:

$ # Query AC adapter.
$ cat /sys/class/power_supply/AC+(AD|1)/online
$ # Query the battery.
$ cat /sys/class/power_supply/BAT1/+(charge|energy)_full
$ cat /sys/class/power_supply/BAT1/+(charge|energy)_now
$ cat /sys/class/power_supply/BAT1/+(current|power)_now

The sixth one is an infrequent, from time to time procedure of adjusting the Hardware Clock and the System Clock in the same time:

$ # Set the Hardware Clock and the System Clock unconditionally, non-synced.
$ sudo hwclock --set --date="CCYY-MM-DD hh:mm:ss" --localtime && sudo date MMDDhhmmCCYY.ss
$ #                          ||      ||                                      ^^    ^^
$ #    YY - Year             ||      ||                                      ||    ||
$ #    MM - Month            ||      |+------------ Day of month ------------+|    ||
$ #    hh - Hour             ||      +----------------------------------------+    ||
$ #    mm - Minute           |+---------------------- Century ---------------------+|
$ #    ss - Second           +------------------------------------------------------+
