10 obscure Linux apps you should know about

Nice list (Bookmarked).

The regular expression debugger (Kodos) looks like it should be really useful (since I basically don't know anything about regular expressions).

I'm too busy or lazy to try a lot of new things. Reading someone else's stuff every now and then helps a lot. There are two of these I am downloading now. Thanks.

I have a few that aren't anywhere NEAR as "tech-geek-guru" centric.....:
Beesu - I dont evne know what it really IS.....but when I wanted to delete a folder and was gettingt an error message that it was unable to be deleted......moved....etc. I ran this and then it disappeared, I think it's some kind of "Menu Editor" for your Main menu selections that appear when you right-click, because the option to "Change Owner & Permissions" wasn't there UNTIL I ran it!

BleachBit - The best thing for my Fedora 17 machine since the Linux kernel! Everytime I run this app my machine emerges as if it's almost new. It gets rid of a lot of "fluff" that builds up over time.

GParted - The best tool for partitioning hard drives....both internal and network attached....hands down a necessity for any admin's Linux Tool Kit!

ClamAV - It may be hard to get it up & running, but once you do, it helps provide peace of mind just knowing that SOMETHING is minding the store and that no one can just waltz right in unannounced!

is a Root Launcher, there are others as well but this one only works in Fedora based systems as far as I know. Its a graphical alternative to opening a terminal and using 'su'

It creates a Root session that you only need to password into the first time, it then runs in the background and launches tasks with Root privileges when you need them from a mouse click.

I have to say, this is a pretty stupid thing to have laying around. If you need to be root to do something that you cant setup your user for, you probably shouldnt be doing it for starters.
And if you know this, then you'd be logged into a terminal anyway...

iftop is a command-line system monitor tool that produces a frequently-updated list of network connections. By default, the connections are ordered by bandwidth usage, with only the "top" bandwidth consumers shown.

cURL is a computer software project providing a library and command-line tool for transferring data using various protocols

I prefer Ubuntu Tweak over Computer Janitor - at least the versions through 10.10. Computer Janitor has destroyed my system more than once. In the later versions, such as Mint 12, it loops forever cleaning up "older kernels" and never cleans them up.

This is a nice list, but it might be a good idea to include an indication if the tool is distribution specific. It doesn't make sense in the Linux world to assume that everybody is running Ubuntu. e.g. #3, Computer Janitor.

For Ubuntu, I find these invaluable:

* Grub-customizer -- published via Daniel Richter's PPA. Graphical set-up of GRUB entries, allowing you to edit the stanza titles, hide unwanted boot stanzas, change the ordering of stanzas, group in sub-menus, change the splash screen size, etc. Excellent tool.

* nautilus-open-terminal -- Nautilus extender to open a terminal in the given folder.

* Byobu -- 'screen' on steroids. Look up either 'byobu' or 'screen' if you don't know what these "super shell" tools are.

* gprename -- group file renamer.

* FWKNOP -- Super-secure firewall knock operator, using SPA to open a given port for an originator at a given IP number. I use it to unstealth SSH ports for entry.

* testdisk -- reconstruct deleted/overwritten/lost/damaged partitions. A lifesaver...
