Learn 10 Good UNIX usage habits

It’s been a while since i posted something about work.. or hobby.. hehehe.. here’s one.. :)

Adopt 10 good habits that improve your UNIX® command line efficiency — and break away from bad usage patterns in the process. This article takes you step-by-step through several good, but too often neglected, techniques for command-line operations. Learn about common errors and how to overcome them, so you can learn exactly why these UNIX habits are worth picking up.

But of course, di ko sya ilalagay lahat dito.. puntahan nyo nalang un link kung gusto nyo basahin buong article..hehe.. list ko lang ung tips in summary… :

1. Make directory trees in a single swipe
$ mkdir -p tmp/a/b/c or
$ mkdir -p project/{lib/ext,bin,src,doc/{html,info,pdf},demo/stat/a}

This is much faster than making the directories one by one…

2 . Change the path; do not move the archive
$ tar xvf -C tmp/a/b/c newarc.tar.g

This is me.. hehe.. whenever I install a downloaded package, I always move the archive to the location i want it to extract.. We don’t need to do that! That’s what the ‘-C’ take is for…

3. Run a command only if another command returns a non-zero exit status
$ cd tmp/a/b/c || mkdir -p tmp/a/b/c
$ cd tmp/a/b/c || mkdir -p tmp/a/b/c && tar xvf -C tmp/a/b/c ~/archive.tar

First example.. the mkdir only executes if the first command (cd) is successfully executed.. same din pala with the second example.

4. Quote variables with caution
dami pala.. you sysad guys just go the link.. hehehe… any check out the christmas decorating tips
