Unix has a huge number of directories and no good way to navigate them. Famous cd command is too simplistic to help when you have over 10K directories in the directory tree. the right way was actually invented in DOS with the advent of NCD and Orthodox managers but Unix is lagging behind and there although both orthodox manager and NCD clones re available they are not widely used.

The IJ Bash Environment is a packaging of part of the way I set up my own bash + xterm environment in Linux. There isn't much code to it, but a little script code can go a long way, and it appears to be sufficiently original to be worth sharing.

These are answers to frequently asked questions on channel #bash on the freenode IRC network.

This tutorial assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction . . . all the while sneaking in little nuggets of UNIX® wisdom and lore. It serves as a textbook, a manual for self-study, and a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts.

We’re a group of Linux administrators that wanted a place to share bash shell scripts and Linux command tutorials with other Linux users. BashShell.net is the site we’ve chosen to index tutorials, tips and shell scripting lessons as we come across them.

So, instead I went and did a little rewrite of it. In a simple and pure bash script. I duplicated the functionality of the daily mode (fetch images per day and put them into a daily subdirectory, create html files for them) and didn’t bother with the “fetch a random strip one” as I never used that. Turned out at 276 lines of shell script that can even fetch alt/title and not break on funny characters in them, yay.

The GNU Project has provided dozens of useful utilities that you can find on almost every major Linux system, but many new Linux users have no idea where to start to learn these handy utilities. In this tutorial, I'll cover a few of the utilities that you can use to measure file system usage, verify the size of files, and take a peek into larger text files like Apache logs.

It takes years maybe decades to master the commands available to you at the Linux shell prompt. Here are 10 that you will have never heard of or used. They are in no particular order. My favorite is mkfifo.

#!/bin/bash if [ -x $1 ] then sleeptime=3600 else sleeptime=$1 fi echo "xmms will stop in $sleeptime seconds..." sleep $sleeptime && xmms -s
