HakTip

I've gotten tons of feedback on recent HakTips and here are some of my favorite tips and tricks from you guys:

Robert sent in another great tip: I keep my .bash_history file edited to my favorite commands, options, and arguments. They are,

lynx -accept_all_cookies lynx_bookmarks.html

irssi -c chat.freenode.net -p 6667 -n babysprite

irssi -c irc.sdf.org -p 6667 -n rbigelo

irssi -c irc.twit.tv -p 6667 -n Me

by using a favorite text editor, which is vim .bash_history. So for the next Terminal session, I can simply [up arrow] to the desired command, option, and argument.

This next tip is from Bill: A couple of terminal commands to let you know what kernel and Ditro you are using

# uname -r - this will let you know what version of Kernel you are running

# cat /etc/*release - Let you know what version on distro you are running

This one is from Mr-Protocol again: I figured this would be a cool idea you could pass along for your HakTips. I found it via SlashDot and figured maybe more could get some use out of it. It's a web based ""Learn Linux the Hard Way"" with a good amount of exercises at the bottom of the page. Maybe this could give a guideline to progress in learning the basics for people. The list of exercises include vim, language settings, bash, job schedulers, file systems, networking and performance, and kernel.

Learn Linux the Hard Way

Pedro says: In the last episode of HakTips you were explaining some keyboard shortcuts. I know one that's pretty helpful. Many times you're writing a long command but realize you have to issue another command first so it get's pretty messy. You hit enter with the partial command, issue the other and then go up in the history or you discard the command and then have to type it again or even copy the command selecting it with the mouse (now with keyshorts -too long-). That's painful. The solution: Ctrl+q. It seems like a quit command but it isn't. It yanks the current line, let you issue another command and automagically pastes back the previous command on the next prompt.

Example:

$ rm -rf file (ctrl+q)

$

$ ls -la

(list of files)

$ rm -rf file (appears again)

He goes on to give us another shell option: I would recommend zsh. To get started you may want to try oh my zsh (https://github.com/robbyrussell/oh-my-zsh), it's like a framework for zsh with lots of great stuff, mainly for developers. As a simple example, with zsh you can do: $ rm **/*.tmp

That will delete all .tmp files under the current directory and it's subdirectories. With bash you may have to pipe find into rm or something like that.
