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?
I have this extremely simple script called startmyth:
Code:
#!/bin/bash
sleep 10
export DISPLAY=:0.1
exec /usr/bin/mythfrontend &
when I execute it as ./startmyth, it works fine. But when added to Gnome's startup applications (System > Preferences > Startup Applications), Mythtv does not start! What gives?
I just installed 9.10 and this is my first time using Ubuntu. I was using Kubuntu before and used KPPP with my Verizon USB720 wireless card. It's the type that gets internet access through the cell towers.I installed KPPP but when I try to start it I get this error:
Quote:
Could not launch KPPP
Failed to execute child process (permission denied)
I tried Gnome PPP and it would open but not connect. This is what is in my log files"
Quote:

After doing much searching and reading I figured out to open Gnome PPP from the terminal with sudo. When I do that it works fine. Also KPPP opens that way although I haven't tried it to see if it connects. Although this works it's not a very convenient way to connect. How can I get it to work without doing this?

From my terminal : >> libreoffice -writer gives :
But if I run it from the menu (applications->office->libreoffice writer) or with sudo it works fine. so something's happening with the permissions, I goes, but I don't quite understand what's wrong. I've tried deleting .libreoffice but this doesn't help. I'm using libreoffice3.3.2 and Ubuntu 11.04.
I am starting to learn about the nuts and bolts of Linux and I wanted to have an option in my Grub boot loader to boot up without x window or any services just a log in so I can test changing config files and experience a system that isn't bogged down by all the things that come along with them.

View 6 Replies View RelatedThere 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'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?
I login as normal user. I can 'su root' fine - password authenticates. However, If I try to run System->Administration->Users/Groups, when it asks for root password, it is rejected. When I run updater, it reports failure to authenticate, but doesn't even ask for root password beforehand. Is there a cached password someplace?

View 3 Replies View RelatedI'm really running into a wall trying to figure this out. I have a Bash script and narrowed down the one command that doesn't seem to work via cron and it's my pgp decrypting line. Works fine if I run the command via terminal but if I run it via cron it doesn't output anything.crontab -e shows the cronjob and it runs, creates the log file with no output. Is there maybe something I need to run as well? Permissions look set, unless the cron is running as a different user(was under the assumption if it showed up under crontab while logged into that user, then it would run as that user.

I 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 ....

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.

What is the difference between shell , console & terminal?
I often have issues starting my window manager--xfce. My computer misbehaves in one of 3 ways, one of which is to fail to open X, but generate several screens of info. I want to paste that info to this site, but since I'm in the shell, not the terminal (please correct my vocabulary if it's wrong here), I don't know how to copy and paste the output, since right-clicking doesn't give me a menu. Even if I could copy I'm not sure the information would be accessible in X. Are there any other options?
