Slackware :: Determine Native Screen Resolution From Shell?

Ubuntu :: Bash: Determine If Running In Terminal?
Jul 10, 2010I'm writing a bash script to move files around based on various bits of metadata. For a few reasons, this script will be run regularly both from the terminal, and from the nautilus-scripts folder ("graphically", if you will). What I'm stumped on is having the script defer outputs based on which mode the script is running in. For example, how can I have the script know whether to echo error statements, or pump them out to zenity based on the method of invocation?

Ubuntu :: Shell Command For Finding All Packages That Provide A Certain Virtual Package?
Jul 29, 2010I want to get a list of all packages that provide a certain virtual package. A way of doing this would be to write a shell script that parses all output of Code: apt-cache search -f .* And spits out all packages that have the virtual package in the provides section. The problem with this approach is that it takes an awful long amount of time to execute. I guess that there should be a simple command that does this in an efficient manner, but which I wasn't able to find.
View 1 Replies View RelatedProgramming :: Pseudo Virtual Files In Shell Script?
Jan 30, 2010Perl has the concept of pseudo virtual files where data can be appended to the end of the script, & Perl will treat it as a legitimate source of data:
Code:
$ cat pseudo_file.pl
#!/usr/bin/env perl
use strict;
while (<DATA>) {
print; }
__DATA__
1
2
3
$ perl pseudo_file.pl
1
2
3
$ _
I would really like to be able to do something similar in a Bourne shell script where I don't have to manage a collateral text file which is prone to getting lost. Does anyone know if there is a similar construct in shell programming? I would have thought this feature was a remnant that Perl inherited from its shell programming roots, but searching on the Web has revealed nothing of consequence.

Feb 9, 2010I'm running ubuntu 9.10 on a Dell XPS M1530. Sometimes i get a _VERY_ loud beep-sound, eg when i run out of battery or, the case that has me coming here when i'm working in a virtual terminal (tty1-6) and hit backspace once too often, that is, when the command line is actually empty.Not that big of a deal you might think, but, especially when you're wearing good (read: possibly loud) headphones the experience is that god damn unpleasant that i'd like to make sure it won't happen again.Oh and well, just hitting mute (in gnome, which doesn't have a lot to do with tty1 anyways) won't do the job.

May 27, 2010I imagine I'll have to install something, but Google has shed no light for me thus far. And just to clarify, when I say virtual terminal I mean the terminals accessed by CTRL+ALT+(F1-F6). I'm going to be doing a challenge/learning experience where I don't allow myself a graphical interface for a month. way around BASH through adaption. However, if I have to go a month without music I will go insane.
So, even if this is possible can I listen to music from the internet (....., playlist.com, etc.) or just music on my hard drive? And I'm not sure if this thread belongs in Desktop Environments or not, that section seemed to focus on graphical interface.
Ubuntu :: Virtual Terminal's Text Overlapping?
Aug 20, 2010I cannot have any more than 47 characters on each line of my virtual terminal without everything on that line disappearing. The text is apparently still there, since commands that need more than 47 characters still work but the text stays hidden. After the text has been overlapped I can type as many characters as I like and it no longer overlaps, but my PS1 on that line and all previously overlapped text stays hidden.I'm almost certain that the problem is in my bash configuration since it happens in a terminal emulator as well as the virtual terminal.

1. Just to confirm, I need to place the above in a file with #!/bin/bash at the top and make it executable.
2. How do I know when the VMs have safely shut down so I can start the copy? I guess I can either a. wait a specified amount of time b. run some sort of if statement to confirm they are off.
3. How do I use Rsync or cp to copy to the backup folder?
4. How will I know the copy is complete so that I can start the VMs again?

View 3 Replies View RelatedUbuntu :: Gnome-terminal Not A Login Shell / Why Is So?
Mar 3, 2011I'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?
