Getting Help from Console

If you’re in console (aka virtual console) doing an install or repairs on a system, it’s good to know how to get help if problems occur. “Ground Control…” To get help in console you can use a chat client. Read this page on how to set up irssi – a terminal/console IRC program. The guide […]

Customize man page colors with ‘less’ definitions

Man pages by default use less for displaying. I’ve used vim before to for colored text in man pages but something got bjorked in an update. To have color with man pages termcap will need to be invoked. Thanks to nico for the tip. All that needs to be done is to export bold and […]

Updating BIOS with Linux

If you don’t have Windows installed and you need to upgrade your BIOS, Linux does have the tools to be able to create a BIOS flash CD. Not many companies make Linux flash utilities and alot of these utilites are DOS utilities so a bootable DOS disk is needed. This is a simple, easy way […]

Color Output on Bash Scripts (Advanced)

I talked in a previous post about basic bash script colored output using the tput command. The tput command works for basic coloring (providing seven colors to choose from) but ANSI also provides a 256 color palette. Note: Not all terminals support ANSI, but most do. ANSI color coding is in this form: \033[01;38;5;160m The […]

Color Output on Bash Scripts

Users who have been using Linux for awhile often learn that creating a basic script is a good way to run multiple, often-repeated commands. Adding a little color to scripts can additionally provide nice feedback. This can be done in a fairly straight-forward way by using the tput command. A common way of doing this […]

Linux Tidbits

Regular commands I use every day in Linux plus a few eclectic ones. Basically geared to the new user. Tips or thoughts, please let me know. Man pages In Linux there is a manual for just about anything. Learn about almost everything by “man command” in the terminal. (e.g. man ls). Or type “command –help” […]

Creating Quality Web Sized PNGs with ImageMagick

Note: This is a post with me messing around with ImageMagick and it’s good food for thought, however as a reader pointed out I accidentally started with a lossy image and turned it to a lossless image which was a mistake on my part. I recently posted The Battle for Wesnoth – 1.4 picture review, […]

Command Line to Clipboard

Update: Script has been updated to add pipe support. Thanks to Nathan who allowed me to use his improvements. It’s really something to be learning Linux. The more I learn about Linux the more I learn it’s about manipulating letters and numbers (well, this is more programming than anything but Linux is a lot about […]

Purge memory trick

Linux does a good job when it comes to memory allocation. If memory isn’t being used or hasn’t been used for awhile it gets put into a cache where it can readily pulled. At times though this cache can become pretty big (especially for a program that has a memory leak). If a good number […]

Background a Process/Program

At times it is useful to see the output of what a program produces by typing its command line name in the terminal (for instance for debugging), at other times typing a program in the terminal just takes up space that could ordinarily be utilized for something else. Launching programs from the terminal can be […]

Cron Alarm Clock

Surprisingly I found out that there are a lack of alarm clocks in Linux. I’ve tried a few but really was impressed with none. So I decided to go with what the Linux uses for some of it’s timed events: Cron. Cron can be a good alarm and its easy to use. The program crontab […]
