LQ Poll: What's your favorite Linux terminal trick?

Shiori-kun · 10-02-2019, 08:15 PM

Since I do a butt load of remote shell work, screen is my favorite tool. As for key/code tricks; tab-complete, pipeing, && (command stringing) and arrow-up

When you are using ssh for a remote login and the far end hangs or the far end terminal emulator becomes unpredictable, enter the command: ~. (tilde dot) to close the connection. It preserves your client side terminal session. You can then just hit the up arrow key to invoke ssh again.

Learned a little using

Code:

 locate .ko

when searching for driver module location for a thread today.

I was like this is the WORD "Linux" and then I was like NO what did I do.

I should have posted my first comment a few years ago, however, I'm consumed with Linux now and fewer windows os versions.

This might seem stupid but I can't tell you how happy I was to learn that the middle mouse button does quick copy/paste

mkdir /tmp/foo-bar-baz
cd !$

I like all regular expressions. You can do a lot with them.

find . -name *.c |xargs grep main()

I have used the following two aliases for decades, and install as the first thing in any new shell environment:

Code:

alias p='pushd'
alias P='popd'

They make traversing down and up directory hierarchies much more convenient. Use like this:

Code:

erkki-desktop2:.../~$ p sub
~/sub ~
erkki-desktop2:.../sub$ p sub1
~/sub/sub1 ~/sub ~
erkki-desktop2:.../sub1$ P
~/sub ~
erkki-desktop2:.../sub$ p sub2
~/sub/sub2 ~/sub ~
erkki-desktop2:.../sub2$ p sub3
~/sub/sub2/sub3 ~/sub/sub2 ~/sub ~
erkki-desktop2:.../sub3$ P
~/sub/sub2 ~/sub ~
erkki-desktop2:.../sub2$ P
~/sub ~
erkki-desktop2:.../sub$ P
~
erkki-desktop2:.../~$

I did not invent them, I am not sure any more, but they probably originally came from some BSD unix .cshrc .

Snap. These are also my favourites

Probably using curl to send texts. I have a script that acquires my gmail password (uses a hash I created to check that I entered the password correctly). So, I can use that to store my password in a bash variable with no need to store the password in my bash history. Then, I can send a text like this:

Code:

text_pw $password $my_name machine_name:\ this\ is\ a\ text\ message

Pretty useful. I start jobs all the time (say compiling with make or cp of an extremely large file) that take an extended period of time. So, I start screen. And, I type out whatever command followed by a semi colon. Then, I type myself a text message and start the job. Then (of course) detach from screen and (knowing me) detach from whatever remote machine I'm attached to. And when the job stops, I get a text message.

I'm pretty proud of this one.

For those that like ctrl-r (to activate 'reverse-i-search'), take it to a much higher level by installing 'hstr' ( https://github.com/dvorka/hstr )

I like the terminal for purging if/when I delete something.
