I am trying to use Ubuntu terminal to execute unix commands. However, the dollar sign that usually appears in shell terminal is missing. Please see the attached screenshot image showing the terminal without the dollar sign. I cannot run any unix commands like cd, ls-l. Please advise how I could fix this problem.

For example,

should become

I'm trying to setup a linux computer to connect to my works wirless. It uses a WPA2 password with a dollar sign in it. I can't input it into wpa_passphrase because it thinks dollar sign means some command.
How do I tell it that the dollar sign is part of the password?
i have a bunch of ubnt nanostations M series (wireless access points/routers)... they use airOS (a fork of openwrt). it runs a custom firmware that i made using provided sdk. and the lighttpd uses php/fi 2.0.1.... this is (of course) used to serve the web configuration.the problem: i need to use the ($) in a string but i couldn't. what i need to do is download some file from the internet using wget and have the pid of wget back to keep track of the process, then parse the output to the page.

I have been recently been using Ubuntu machines in my faculty labs at university that have % as the terminal sign for the line rather than the location.
For example,
% kate &
% echo "helloooo" > hello.txt
%
I find this extremely annoying as I am used to % being replaced with a path to the current directory followed by a $. Like a default Ubuntu install.
For example,
james@james-pc:~$ cd Documents
james@james-pc:~/Documents$
I would like to know if there is an easy way to change this to what I am used to? I don't necessarily need the "james-pc" bit, the username would be nice but I really want the path to the directory.
Im using an if statement in the bin ash shell and it isnt working.
Code: if (( 5000 > $available_blocks )) then echo "WARNING Disk space low, "$pct_used" is used" fi
I don't think its a problem with the if. When i use that code it creates a file with name of the value $available_blocks instead of using the '>' sign for comparing the 2 numbers.
I'm having trouble signing in using the sudo in the terminal.
I enter in the line: sudo abc (username = abc)
I get the line returned: [sudo] password for abc:
If I enter my normal login pw i get the message:
abc is not in the sudoers file. This incident will be reported.
If I enter the root pw I get the message: Sorry, try again.
I've just set up the debian OS and am trying to learn the linux way but it's a bit frustrating. so when I set up the system originally It had me make two passwords one for root and one for my user acct. So how do I get the sudo terminal to work?
I am running 11.3 with Remote Admin(VNC) turned on. This has installed TightVNC.I also have also enabled xinetd to manage the startup of new (incoming) VNC requests.All this is working just fine. So, what's the problem, you ask? Its that missing Shift+3 symbol. To reproduce, I run TightVNC (viewer) from a variety of clients (Win & OpenSUSE) to a number of OpenSUSE servers with xinetd managed VNC services enabled. The Xvnc sessions start and the clients display the KDE log-on screen. You will notice that in the username field that the sign is not displayed.
I have run a parallel VNC service (is it Xvnc or vncserver?) which gave me a twm session. It also is missing thesign, so I conclude that it is not KDE that is causing the problem?Secondly, a scan throughog file produced by the parallel VNC service shows:Code:KbdAddEvent: unknown KeySym 0x3a - allocating KeyCode 92 Has anyone any suggestions on how I can get my pound sign?
I just installed F15 and although different, I like it a lot. One thing I don't like, however, is the default auto-completion of environment variables in the terminal. In F14 and older, if you type for instance
Code:
ls $HOME and hit TAB, auto-complete will list the contents of $HOME to search deeper, so to say. But in F15, the terminal automatically escapes the $ sign. If you do the same as above, you get
Code:
ls $HOME
instead of
Code:
ls /home/benny/
how to change the auto-complete settings of the terminal so that $'s are not escaped anymore?

Just installed gnome-Shell in Natty Narwhal. the only problem know is that all the icons have disappeared and the theme has gone to a more "basic" look. No matter what desktop session I choose (Unity, Gnome-Shell, Classic) I can't change anything back since the "appearance" menu seems to have been removed while gnome-shell was being installed.
View 9 Replies View RelatedI used the official PPA to change to Gnome Shell in Natty; it all works well (after sorting out the theme) and pleased I can stick with Ubuntu and the latest Gnome, but...
I am missing the bluetooth and power icons (top-right), anybody know how I could get those back?
There are a couple commands I want to run in a terminal that require me to provide my password. I really don't want those commands ending up in any kind of history or anywhere else where they could be seen by someone after the command was run. Are there any shells/terminals for Ubuntu that I could use (or options to bash/zsh/etc) that would give me a secure environment where I don't have to worry about my history being kept?
View 3 Replies View RelatedI have a shell script that I want to be able to run from the terminal just by typing "topcat", regardless of where I am or what user I'm under. How would I go about changing the bash configuration files (if I have to) in order for that to work, for me and for the other users on the computer (I have root access)? As it stands right now, I have to type "/bin/topcat/./topcat" in order for it to execute
View 3 Replies View RelatedI've seen lots of posts all over the Internet that advise users to check the "Run command as a login shell" checkbox in GNOME Terminal under Edit->Profile Preferences->Title and Command.
This makes gnome-terminal run bash/csh/tcsh/ksh as a login shell, which it does not do by default. In turn, running gnome-terminal as a login shell sources the system and user login scripts. This sets up things like colored ls etc.
It seems like gnome-terminal should be a login shell by default. Why isn't it? I've never seen a good explanation of why gnome-terminal isn't a login shell. The "Run command as a login shell" checkbox must be unchecked by default for some good reason, right?
If i type command
Code:
export ROOT=$(pwd)
directly into a terminal i can see my current directory as a value of enviromental variable ROOT. I can check it with printenv command.
Same command does nothing when executed from a script. Why?
In a shell script. And use that in a condition.
Something like:
Code:
if(pts) echo "emulated"
if(tty) echo "virtual"
Green on black = general shell
red on black = shelling in as root to a server
gold on black = media, irc
what colours do you use?

View 5 Replies View RelatedWhen 1 of the terminals logs in most of the time they do not get the top or bottom "panels". I have had to add 2 side panels to get the buttons and menus.This only happens to 1 user when she logs in. IS there any settings that i could change ? When the user is logged in she can do what ever she likes when she gets the panels back. and the speed is lovely.

View 5 Replies View RelatedI just installed Ubuntu 10.04 for some development. I was trying to set some environment variables are noticed that when I hit 'set' inside a terminal (to dump environment vars) I get the usual first few variables but then I see a whole lot of script code ....
Code:
WINDOWID=23068675
XAUTHORITY=/var/run/gdm/auth-for-sid-5IDovs/database
XDG_CONFIG_DIRS=/etc/xdg/xdg-gnome:/etc/xdg
XDG_DATA_DIRS=/usr/share/gnome:/usr/local/share/:/usr/share/
[code]....
I've installed a lot of tools (NetBeans, Ruby, Java, build-essentials etc) but essentially I installed Ubuntu today - so it shouldn't have rotted out this quickly. is this hijacking of environment vars to embed script code intentional with Ubuntu 10.04?
i've finally got a NIX environment...yipee! Installed opensuse 11.2 in a dual boot with windoze with no problem whatsoever. unfortunately, my NIX skills are sadly dated or maybe things have changed or both. in any case, i have a rather trivial problem that i have not been able to figure out.
i go to gnome terminal to get to the bash shell, no problem except when i do things like cat, less and so on. the commands do what they do then when done the last line output is "some text" and "(END)" - at the completion of the command it does not return to the bash shell. i've tried ctrl-everything, enter, escape, actually all keystrokes i can think of to get back to the bash shell...no luck. man and docs have not been helpful or i simply missed the answer (i'm a little saturated at this point).the only thing i've been able to do to solve my dilema is close the terminal an start a new instance, not elegant but works.
What are the differences between shell , console & terminal?
This probably sounds like a stupid question but I'm having a lot of trouble clearly differentiating between a shell (such as Bourne or bash) and the Terminal application in GNOME. I realise that both are completely different but I can't seem to find a clear answer written in text. Could anyone clearly distinguish between both?
I want to disable all color in my shell. Not ls, not nano, not vi, nothing.
