This new section doesn't have much traffic, so to up it I'll start posting scripts every now and then that some might find useful.
For our first snippet, diskmap() maps out files greater than or equal to 50 MB (not MiB); the spinner uses braille because it works well with utf-8 consoles.
This next snippet renames all files lower-case, which can be useful at times.
Ever wanted to see what kind of commands are available in your '/usr/bin' path? Well, here's a "cheat-sheet":
This next command has nothing to do with the illicit drug "LSD". One of my friend's dad used this alias for only listing directories within a certain path. I, however, loved the alias so much that I modified it to meet my purposes:
Note: the Z flag only works if SELinux is installed. Remove the 'Z' if there's no SELinux data.
If you have a good command of regular expressions, then, pcregrep and egrep are just fine. But, if you're lazy and you use agrep, you may want to try this out:
That's all for now. Enjoy!
