Linux Fu: Debugging Bash Scripts
A recent post about debugging constructs surprised me. There were quite a few comments about how you didn’t need a debugger, as long as you had printf. For that matter, we’ve all debugged systems where you had nothing but an LED to flash or otherwise turn on to communicate …read more

At first glance, it might not seem to make sense to write shell scripts in C/C++. After all, the whole point to a shell script is to knock out something quick and dirty. However, there are cases where you might want to write a quick C program to do something …read more

If you want a different style of command line editing, there’s an option. You want the tab key to match files regardless of case? Another option.

Linux Fu: Modernize Your Command Line
If you use Linux and its associated tools on the desktop or on a Raspberry Pi, or on a server, you probably have used the command line. Some people love it and some people hate it.
