Ubuntu :: Opening Applications (only Gnome-terminals) In Defined Workspace?

Aug 18, 2010

Ideally I would like to set a keyboard shortcut to open a set of applications. The applications (mainly different gnome-terminals) should be opened in different, previously defined workspaces. I had a look around but could not find a simple solution (maybe it could be done in devilspie but I would like to avoid that).If I limit myself only to gnome-terminal and instead of using the keyboard shortcuts call the application in the shell the placement of the terminal can be done by using "--geometry" (see "man gnome-terminal" and "man X") e.g. "gnome-terminal --geometry 50x20+200+300". wmcrtl show me that my 6 workspaces are treated as one desktop (my interpretation - maybe wrong):

$ wmctrl -d
0 * DG: 7680x1024 VP: 0,0 WA: 0,1 1280x1023 Desk 1

General :: Removing Previously Type Commands At A Remote Server?

Aug 7, 2010

I am ssh'ing into a remote server and then su'ing to root.The problem is that sometimes, I have not paid enough attention to the console message, and I have accidentally typed in the root password at the command prompt (when for example, I had failed to provide the root password correctly the first time - so su prompt went away).

I remember reading somewhere that a history of commands typed at the console is kept somewhere.I have 3 sub questions

Where (which folder) is the file stored?

Can I edit that file and remove the root password from it?

Being the paranoid person that I am, I wonder if there is a more secure way of logging into my server - other than ssh (or am I being TOO paranoid?)

My server is running a headless Ubuntu 10.0.4

General :: Unable To Own Previously Saved /home Files On New External USB Drive

Nov 2, 2010

I have just had to reinstall my OS (Sabayon) onto a new and larger hard drive (dying old disk). I quickly saved all my old docs in /home on an external USB drive (formatted and then created an ext4 file system) before the swap and installation.

After getting the new disk running I connected the USB external disk. First I could not access the drive at all, but that seems to be fixed. Now I want to bring all my files back to my new /home folder but apparently they (especially the former MS Office .doc, .xls, etc files, not so much the OpenOffice files) are �read only� and I don't have permissions anymore. I am able to create directories on the external, and can move files back and forth, but don't seem to own many of them.Sabayon automatically mounted my external disk in /media/disk, rather than /mnt, so I've left that alone for now. After searching here and elsewhere for info, I tried a few things (below): For access I added a line to /etc/fstab:


/dev/sdb1 /media/disk ext4 noauto,rw 0 0

Here's what I've done to try and fix ownership already:

in /media I:


# chmod 775 disk

which gives output of:


media # ls -l
total 4
drwxrwxr-x 2 root root 4096 Nov 1 21:30 disk


I'm not sure what the �total 4� refers to since there is only the one directory �disk� inside /media but I assume that's not part of this issue... Does adding umask=0 have anything to do with this, and if so where does that go?

General :: Get 2+ Terminals In BASH Script?

Jan 19, 2010

I am making a bash script. I have captured user input like so. code...

But it does not work. Airodump-ng "takes over" and the script does not continue.

How do I make it so that I can make a new Terminal, or allow more commands to take place on the current one, allow the output from airodump-ng to be shown, and keep the caught user input?

I'm using Ubuntu 9.10, GNOME and would like it so that anyone with a GUI Terminal, Konsole or whatever can execute the script successfully.

I'm confused...I looked up on Google and couldn't find anything! Just "Beginners guide to Bash Scripting" and "How to BASH script" but nothing relevant that answer my question!

General :: Socat And Rich Terminals - No Job Control In This Shell

Mar 24, 2010

socat - exec:'bash -li',pty,stderr,ctty -> bash: no job control in this shell

What options should I use to get fully fledged shell as I get with ssh/sshd? I want to be able to connect the shell to everything socat can handle (SOCKS 5, UDP, OpenSSL), but also to have a nice shell which correctly interprets all keys, various Ctrl+C/Ctrl+Z, tab completion, up/down keys (with remote history).

- Found "setsid" socat option. It fixes "no job control". Now trying to fix Ctrl+D.
- socat file:`tty`,raw,echo=0 exec:'bash -li', pty, stderr, setsid, sigint, sane. Not it handles Ctrl+D/Ctrl+Z/Ctrl+C well, I can start Vim inside it, remote history is OK.

General :: Track Spend Time On Computer?

Sep 4, 2010

Possible Duplicate: time tracking application on linux Every Linux time-tracking application I've seen assumes you're tracking time for projects, perhaps to create invoices later for your clients. This is not what I'm looking for. Rather, I just want some insight into how I spend my time on my computer. I'd like to waste less time on my computer, and spend my time on more productive tasks. The first step to improving anything is to measure it. But I can't be bothered or remember to click on some icon and switch "projects" every time I change from my terminal to browsing ....., or something like that. I want the time I spend on different applications tracked automatically.

General :: What Format Should Rip A CD Track In For A Windows User

Apr 4, 2010

I wanted to show a track from a CD to a friend who uses Windows. I tried to rip it in MP3 (LAME) format, because I couldn't remember whether Windows Media Player can read OGG or FLAC (whatever that is) format. Due to some kind of error (no explanation given other than "command failed"), my K3B would not rip in MP3. Which of the formats can Windows Media Player read? I know it can read WAV, but that's inconveniently large to send by e-mail or over an instant messenger.
