Does anyone know of any free services offering debian or ubuntu shells? I want to run IRC remotely with screen, but free services only seem to offer unix shells. I'm not really bothered by that but I feel more comfortable on ubuntu.
View 2 RepliesI want to have an ls' output colorization in gnu screen. Colorization in my system (Slackware 13) is realized by aliasing of ls in /etc/profile.d/coreutils-dircolors.sh:
Code:
$ alias ls
alias ls='/bin/ls $LS_OPTIONS'
where $LS_OPTIONS is
Code:
$ echo $LS_OPTIONS
-F -T 0 --color=auto
But in screen this alias isn't defined. It seems like /etc/profile script isn't executed at shell starting in screen. I think it happens because screen starts a shell not as a login shell. I tried to correct it by adding to ~/.screenrc or to /etc/screenrc. The problem is the same. By the way when I start screen as a root I haven't this problem. What's wrong?
Does anyone know or recommend some software or a script to remotely power on a PC from standby to on, or even better from completely off?
I guess the completely OFF to ON is much more complicated - would probably require an extra piece of hardware(?)
I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!

View 4 Replies View RelatedI am trying to figure out where variables are set for interactive shells? In particular, I am trying to have LS_OPTIONS inherited by interactive shells as it is by login shells. I understand LS_OPTIONS is set in /etc/profile, and this may not be processed by interactive shells but by login shells. However, I also note other variables such as PATH and INPUTRC are set correctly in interactive shells, and these are also set in /etc/profile from what I understand. So how is it determined which variables are inherited by all shells, and which are just for login shells?
View 16 Replies View RelatedLet's say that I have a customized Bash prompt stored as a PS1 variable. My variable gets read every time I invoke a login shell, i.e., when logging in in one of the standard virtual terminal or by invoking xterm with the -ls parameter.
However, when I just invoke the terminal without specifying that it is a login shell, I just get something like: bash-XXX$ as a prompt.
where should I place my PS1 variable so that it could get read even on non-login shells?
i am running ubuntu 10.10 on an aspire 5734z laptop, as 11.04 has a backlight issue, and i am dual booting with win7, which i am currently on. i have/had KDE, xfce, desktop edition ubuntu, and gnome 3 sessions installed. i had noticed recently that startup is taking longer than usual, 2x the time as win7, ubuntu and windows are both 32 bit bytheway. after grub, it would be a black screen with only '_' displayed, followed by a screen that says something about sql stuff. i figured this could be the reason my startups were long, and as i dont use sql (that i know of) i decided to just remove it and hope that would fix the problem... yeah, im a linux-noob. i went to software center, searched for it and removed the first entry, and it said it would remove some other stuff, mostly sql named things, plus shotwell and evolution, which i also dont use. after it went thru applying changes, i selected the next one on the list for removal, and the software center froze.
i logged out of the gnome3 part, and logged into ubuntu desktop edition. i then only saw a wallpaper, both of the default panels were gone. at this point i decided a reset was in order. i logged back into the default ubuntu desktop edition part, and the panels were still missing. i figured i would login to gnome3 or kde and see if i could get something figured out from there, but they are missing from the drop down box. the only ones remaining are ubuntu (desktop, recovery and safemode) and xcfe. i logged into xcfe only to find out firefox is gone. i am not familiar with xcfe, i only added it to maybe use sometime when i need to extend battery time, and with no click here to get online - icon in the panel, i figured my best bet was to return to windows and plead for help, before i tried to 'fix' something else, and made an even bigger mess. i dont know what i couldve done to basically render my ubuntu useless to me, to get rid of my panels, firefox, and i dont even know what else.. but the only thing i did at all was to remove the top sql entry, which was something like sql3_lib or something like that.

View 2 Replies View RelatedI'm finalizing the the dual-boot addition that I recently completed. I've added lubuntu to the LT3114u Netbook that I use. That's done, now I'm migrating my user environment back from the Cygwin one that I've been using on Windoze, as of late. One of features that's been useful has been the global environment management possible with the windoze UI functions. As I coded my emacs environment while 'over there' (windoze side), I included a check for the lisp library repository path environment variable EMACSLOADPATH. It is globally available when one logs in, and does not get set in any user scripts, or dot files any to do with CYGWIN or emacs.
While it has been easy enough to set EMACSLOADPATH for the login shell environment, via .bashrc, .profile, and system wide via /etc/profile, I have not been able to have '/usr/bin/emacs23' have EMACSLOADPATH set when invoked via the LXDE UI. Thus, it would appear that emacs is not being initialized with the same environment that any of the shells are (old school?). Thus, what is it that one must update in order to have GNU emacs initialized with the same environment variables as bash? Or, put another way, why aren't the environment variable defined in /etc/profile, ~/.bashrc and/or ~/.profile ending up in the initialized environment upon invocation of emacs23 on lubuntu Linux?

I am having trouble distinguishing between login and interactive shells as they relate to terminals. I understand that a login shell is what is started when you login, and an interactive shell is used by scripts and such. I also get that terminals will use an interactive shell by default. What I don't understand is why interactive shells have no prompt by default. Is their a way to get an interactive shell to inherit the normal PS1 prompt? Is it considered bad to do this? Would it be better to have terminals start login shells, and if so why or why not?

Now with the help of BLFS I am setting up my environment and somewhere I incidentally read, that not every variable is inherited by a child Bash shell. As for the $PS1 and $PS2 variables I know, that they are not inherited by non-interactive Bash shells (and there is no reason why they should in my opinion). Well, as for my first thread I hope the title gives enough information on what I want to know. But anyways: Which environment variables are not inherited by Bash shells?

I posted about viewing desktops remotely (received no reply), as I have an "off task web-drifting" problem with some students in my classroom, due to the fact that I no longer have my old SynchronEyes program. I have Windows Vista Business/XP Pro machines (32 of them in all) and I cannot view desktops remotely, regardless of the fact that 1) the Remote Desktop Service is enabled, and 2) I know the IP numbers and the domain names. How can I view desktops remotely with the Remote Desktop Viewer tool in Ubuntu, with the fact that the IP addresses are correct and the Remote Desktop Service is enabled on all 32 machines?
