View 8 RepliesHow can I start up my Ubuntu Linux in the shell? Then how could I make sure to also get back to gnome?
View 1 Replies View RelatedI need to start a (bash) script in XFCE or GNOME so that, by double clicking its icon, it opens in a new shell window where it can be stopped with ctrl+c. As it is, when I start it, it runs in background (does not open window), so I need to manually start terminal and kill process. Also I don't see the output and that is important.

View 1 Replies View RelatedI just installed GS following the instructions here:[URL]... and the classic way of getting GS to start at login (adding gnome-shell --replace in start up applications) doesnt work.
To start GS now we have to use the command "~/gnome-shell/source/gnome-shell/src/gnome-shell --replace" via the terminal adding that to start up doesnt work either, does anyone know how to get GS to start at login?

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

I recently "upgraded" to the latest skype and now every time I open an interactive root shell, up pops skype. I can close skype then control-C in the terminal window to get the shell I want, but this is annoying to say the least. Maybe my google-foo is off, but all I can find is articles on how to run skype as root, which is no use. I've tried searching the startup files for "skype" (case independant), but so far all I can find is "LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/ /usr/bin/skype" in the root .bashrc which shouldn't be starting the app.
what could be causing this?

I've created a simple script based menu. This menu will be accessed by only a certain users via ssh.When user logs in, the menu will automatically run. (configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.

I have multiple file in one folder. So how to use any script to read in one directory folder and do a same task. I prefer using awk, sed or perl.
I tried, of course:
Code:
awk '/^./ {print}' FILE.TXT
That does not work, I just get an empty output, even if FILE.TXT contains lines which fit the desired regexp I've searched but did not found my way. I'd like to do it with awk, as I want my program to rely only on awk, nothing else such as sed, grep, etc.

I have a situation where I am in a non-interactive shell. I have tried from within my non-interative shell to spawn an interactive shell but my output still does not goto me. Isn't there a way I can somehow go into /proc or somwhere and make the output my /dev/tty1? Or some way else to remedy this?The situation arises because I drop from my restricted shell environment (a sort of CLI interface), into the actual Linux shell. I cannot change the code of the CLI environment I am just faced with being in the linux shell environment and its non-interactive. Its very annoying to have to put > /dev/tty1 after every command I type.
Not to mention it seems damn near impossible to get pagers like more and less to work properly when your in a non-interactive shell.

How can i use different starting and ending delimiters in awk to search for strings or numbers like:

So, DnD is cool - and in Java, it works. Just set the component where the drag starts to allow that:
Quote: tblMain.setDragEnabled(true);
and - yes - the rest pretty much runs itself. I have a JTextField that happily takes the drop from the JTable (be it the whole row - I'm not there yet, still working on that)...but does not raise any events. I'd like the JTextField to raise an event:
- cleaning up the received data, now it gets the raw stuff, and I need an ID from that string
- starting up another void() with the received ID
I read the tutorials but - for blisters - cannot see the "light", please shed some (light, that is)

I'm trying to write a toy linux shell. For starters this is what I'm trying to do:
1. Start a new process with fork.
2. Execute a program in the new process with execl().
3. Redirect the output from the new process from STDOUT to another file descriptor, using dup2(2).
4. In the parent process, read the output from the child process and write it to the screen.
Creating a new process and executing a program in it is no problems, the problem is that I can't seem to capture the output from it in the parent process.

//digenv
//C++arl 2011-03-24
