what are your "most-used" linux programs ?
 

I was doing a regular yum update this morning and noticed that my fedora system has a significant number of GUI programs installed...I've never used most of them yet.
So,i was wondering if someone else is getting their work done with such utilities.It is too difficult and time consuming for me,to try all of them one by one.

Please list which programs do you use most frequesntly on your linux system...so that i can get benefitted too.

In approximate order of how often I use them (1=most often), here are the ones I can think of off the top of my head:

1- Firefox. I would use Chromium, but I've got so many Firefox extensions for which there are no Chromium equivalents.
2- Pidgin. Mostly as an Identica client, running in the background.
3- gedit. It's surprising how often a simple text editor is useful.
4- GIMP. A very powerul image editor.
5- Clementine. A music player/manager inspired by Amarok 1.4.
6- Unison. For making backups of my very large music collection.
7- TrueCrypt. For encrypting files.

Firefox.
Deluge.
vlc.
Terminal.

Iceweasel (firefox lol)
Banshee
VLC
Gedit
Libreoffice Writer
Empathy (I used to prefer pidgin but sometimes it just wont work)
Skype
Evince

I have a huge amount of GUI apps installed and I have used each one but the list above is my daily usage in Gnome and most get used in Enlightenment, Fluxbox, XFCE, LXDE, MATE (Mate has gnome apps with different names). I don't use KDE often so I don't know what I would use in that.

I think the OP is interested in the little tools rather than the full applications? In that case, my common ones are evince, eye-of-gnome, gcalctool, brasero, file-roller, system-monitor, user-mount. If it's applications, then the usual one for me are opera, claws-mail, openoffice, gnucash, and wine.
