df/mount output

I like to see only local/networked/automounts maps with both "mount" and "df" commands. Also, I prefer columns for "mounts"

Code:
df-fs () { 
    df "$@" | \grep -E '^([^[:lower:]_-]+|File)'
}

mount-fs () { 
    ( echo Filesystem Mountpoint Fstype;
      mount | \grep -E '^[^[:lower:]_-]+' | awk '{print $1,$3,$5}'
    ) | column -t
}
Sample outputs:

Code:
br@lorien:/mnt/arwen-sd$ mount-fs
Filesystem        Mountpoint              Fstype
/dev/sdb2         /                       ext4
/dev/sdb1         /boot/efi               vfat

Note: These functions are for bash. If you use another shell, syntax could be different. If you want a shell-agnostic solution, you should replace functions with shell scripts.

echo "scale=3; 19/3" bc -l

is what i like very much. This way one can combine the shell-ability to repeat with the calculator "bc" and really use the box for fast, precise and comfortable calculating.

I recently learned how to use quick history `ctrl + r` in the terminal and I use it all the time now.

* ctrl + r
* Type a command you previously used
* (optional) ctrl + r to go back one entry further
* press enter to execute or arrow keys and type to change your previous command.

Favourite terminal trick
Code:
$ cat ~/.inputrc
 set completion-ignore-case on
"\e[A": history-search-backward
"\e[B": history-search-forward
set show-all-if-ambiguous on

This lets me enter a single letter and then hit UpArrow to go through all previous commands beginning with that letter. Saves me a lot of time.

I am not sure if it counts as a keyboard trick, but better than #9 posted by hydrurga, to cut and paste, instead of CTRL-c/CTRL-v, simply highlight whatever you want to copy, move to the place you want it pasted and click with the middle button of the mouse (can be in a different window for a different application). I use this a lot!

I like in bash:

TAB - Shortcut and time saver
Ctrl + d - Logout
Ctrl + l - Clear the terminal
Crtl + r - Latest commands
Crtl + a and + e - Cursor back to the beginning or end of the line.

sudo apt-get clean && sudo apt-get autoremove

Run when steam gaming performance bogs down. Perfect and immediate fix.

When I have a long command running I add "date" (no quotes) and hit enter... this shows when the long command finished. I sometimes want to know how long it took so I write down the time I started then add that "date" command.

I use "time" command for that... At the end of command execution, it shows exactly how long it took to run; example:

Code:
$ time dmesg

.....

real	0m0.037s
user	0m0.004s
sys	0m0.016s
