Is it possible to run a bash or shell script BEFORE I load slim. This is to do a bit of configuring and file moving before the system actually boots and just generally for a play about!Im wondering if its possible in the innittab file to change the following part:
Code:
ca::ctrlaltdel:/sbin/shutdown -t3 -r now
# Example lines for starting a login manager

I need show the number of process per user, and after the date of the oldest process per user also.
With "ps -eo user | sort -u" i get all users that are running any process. And with "ps U username | wc -l" i get the number of process that the user "username" is running.
But how can i merge both commands for do what i need? Like a FOR or something like that. There is any method of make a FOR using the list that i get with the first command?
And then for show the date of the oldest process.. with "ps U username | sort -k 4" (4 is TIME field) i can show the process of the user "username" sorting they by time. But how can i get the date of the process takes longer running?? I can get only the time, but no the date.
Running Compiz as a standalone WM.Managed to get Slim working, will post how later, but have no sound. If I boot using gdm3 the sound works. Obviously gdm3 loads something Slim doesn't, but can't workout what!Tried adding /usr/bin/pulseaudio --start --log-target=syslog & to my script - no dice, still no sound

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)

I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
below are the details of my system. I have bash as my current shell, some really common commands aren't working.
Do I need to do a re-installation of bash? Or how do I install a selection of bash commands which I need? (for example a subset of [URL])

I presume there is something in the JWM window manager - or Puppy Linux Lupu 5.01 itself that is conflicting with the normal loading of GMPLAYER....
I would like to know how to troubleshoot, and fix this problem if possible (even a workaround would be great).
Does it use Bash or some other shell?
View 2 Replies View RelatedI used c-shell previously in unix. One of the useful command I used frequently is foreach.> foreach a (`cat list`)>> echo $a need to use bash shell now instead, and realized that I can't use foreach anymore. The command is not found. Does anyone knows if there is similar command / function in bash shell?
View 9 Replies View RelatedSo I open firefox from my bash shell with:
Code:
firefox google.ca
it opens firefox, I can browse, etc.
Now if I alt-tab back into my shell, i can't enter any commands in the shell.

Is this possible?
I use ":!shell_command<enter>" OR ":sh<enter>" in gvim to execute shell commands or to get a shell. But I am getting an 'sh' shell. Is there a way to get the 'bash' or 'csh' shell from within gvim?

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.
I changed the default SUSE prompt setting by modifying the shell variable PS1 to display the following information:
u : the username of the current user
h : the hostname up to the first '.'
w : the current working directory, with $HOME abbreviated with a tilde

export PS1="[u@h: w]$ " To add colors to the shell prompt and make a regular user prompt blue I used the following command syntax:export PS1="e[0;34m[u@h: w]$ e[m "

I would like to create some aliases for bash shell. On other Unix/Linux machines I have done this using the alias command like this: alias rm rm -i
When I type that into a terminal on Ubuntu, it looks like alias is not installed. I get this:
bash: alias: rm: not found
bash: alias: rm: not found
bash: alias: -i: not found
I tried adding the alias to .bashrc instead, but then I get the same error message every time I start terminal. Just for fun I tried apt-get install alias, just to see what would happen, and it installed something called libperl-alias instead, and alias still doesn't work.
Whats the difference, and when do you use which?
View 2 Replies View RelatedI am working on a simple script that should take two command line arguments, a [number] and a [name]. The first thing the script should do is check to make sure that no more and no less than two command line arguments have been entered when calling the script - an error message should be delivered if the condition is not true.
If two args have been entered, then the message 'processing "scriptname"' should appear, where scriptname is the name of the script being called. The script should then write to the screen "Hi [name]!", and should write this phrase [number] of times. For example, the command $ myscript 2 joe would produce the output: I have read the manual many times looking for examples, and I am very close by virtue of my own efforts. Further, I have searched these forums and others for good examples, which have also gotten me very close.
