I upgraded from Slackware 64 13.1 to Slackware 64 13.37 a week or so ago. I am now having a perceptible delay of a few seconds when launching commands from the command line, say for example: screen -R.
My laptop is an X200 with 3GB of RAM.
When I'm in OpenBox, I often have a termianl (lxterminal) open in the background. The terminals responds quickly when logged in as my standard user. If I, however, use su to switch to root, there's about a 2 or 3 second delay on the output for any command I type. This delay goes away if I type another character or tap the spacebar. That input is read as normal -- I've accidentally answered 'y' to prompts before.
My machine is an ASUS Eee PC 1001P (1GB of RAM, Atom 450) with an 40GB Intel SSD.
Switching to and from insert mode in Vim is no longer instantaneous since I use tmux. After pressing Esc in insert mode, it takes a noticeable amount of time to actually get out of insert mode. After pressing Esc and any other key afterwards the switch is immediate, and the command for the key pressed after Esc is executed. Any idea what might cause this?The Vim configuration is not the problem as the delay does not occur when I run Vim outside tmux, so this is probably related to tmux somehow. I use gnome-terminal btw.
Also worth noting, it seems I can not define key bindings in tmux for Esc, my plan was to bind Esc to:bind Escape send-keys.Alas, it seems binding anything to Esc for tmux does not work. The same problem occurs in screen as well.
I have a command which on the command line needs to look like this
rlam -if3 '!pvalue -H image1.jpg' > image2.jpg
Nevermind what rlam or pvalue do ... they are part of a program package I am using. The above command works on the command line, and also when written verbatim in a bash shell script.
My problem is: in the script I wish to replace image1.jpg with the content of a variable, e.g.
IM1=image1.jpg
How to I get the script to insert the value of $IM into the command when the pvalue part of it needs to be quoted?
I need to process billions of small files using bash shell commands with limited memory size (256MB). If any of those files contain certain "keywords", the file will be removed. I tried with command:
find . -type f -exec grep -i -l -H "keyword" '{}' + | xargs rm -rf
where all files are located within the current directory. But the command above failed in "out of memory".
I would like to ask whether there is a way to postpone or delay message processing on postfix mail server. E.g. to postpone message transfer/relay for 5 minutes to be able to dequeue mis-targeted emails.I couldn't find anything because these keywords mislead to performance problems.

A start-up script invokes the i8k module: $ udo /usr/sbin/modprobe i8k force=1 which creates /proc/i8k. The man page for i8kctl is straightforward: a few simple commands to read info from the aforementioned file.So. I know nothing about writing even basic bash scripts.

Does anyone know a method of being able to process the complete and literal command line passed to a shell script ? I want to have the command line parameters with ALL characters (including meta characters e.g. $ literally).
So as if there was no shell to substitute or expand parameters nor applying it quoting rules.
I was asked to list passwordless or locked accounts in a fedora system. As far as I know, fedora or RH dont allow passwordless accounts (the system locks the account Edit: ... unless you set passwd -d :-P ), so I might show info about locked accounts.
I am totally aware that I could do a grep or an awk searching for "!!" or "", but my people is asking me to check against passwd -S (which prints info of accounts). The thing, is that in Solaris you can check with passwd -a -s all the users, but in Linux I couldnt find anything similar. what approach do you reccomend for passing, say , the list of users ( like the output of awk searching only user names) to the command passwd -S one by one?
I would like to read unix file permissions into a bash array for processing but tbh I have no idea how to do this. Then I will check for each individual access right l, d, x etc.

I want to change my default shell to tcsh. I used

But if I open a new shell, it is still a bash shell.
How do I make my default shell as tcsh?
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:

I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
However when i logged into it, i noticed that the movements with the curser was extremely slow and happened with a delay, but this only happens when i have an window open, its fine when its just the desktop Same thing happened with Gnome-Shell i think it must be mutter because its fine with normal Ubuntu Is there any solution to this at all?

I have a new installation of Slackware 13.37 on an old Dell Optiplex P4. Right after installation (when I only had a root account) I found that X (regardless of window manager) would develop video problems after a few minutes (horizontal lines, slowdown -- though without crashing). A message board informed me that that there was a bug in my onboard Intel video chip that would require me to enable shadow buffering (which amounts to disabling 2D acceleration). I made the change in the Xorg.conf, and the issue disappeared.
However, once I finally got around to adding a new user, X began acting up again, though I have no idea whether it's related to the earlier problem. Now, after a few minutes, it actually crashes -- though only when started under the new user. Root still works fine. I'm new to Linux, and still trying to sort through all the different logging tools, so I'm not sure what I ought to be posting. Here's the relevant bit from Xorg.0.log:

What happens when the script executes is that the ssh connection works and parks me at the remote hosts's shell login. Therefore, the "firefox" command refuses to execute. I need to know how to make the "ssh" connection occur, stay open, and go into the background so that the rest of the script can execute.If I could also do this with the "firefox" line so that the entire term window could be closed would also be helpful.

It happens consistently every time I boot. Again, this is after I choose the OS to boot, so it shouldn't have anything to do with the standard delay to allow me to choose the appropriate OS.Is there a good way to troubleshoot this and determine what is causing the delay?

View 5 Replies View RelatedNew to Fedora (from Windows), I am up and running ok with packages from the repository but only half ok with Processing, the Java graphics programming front end from processing.org.Their download gave me a .tgz file which Package Manager extracted for me into a location of my choice and where there is now a "processing" shell script.This works ok and I have managed to create a launcher on the desktop. That starts ok but always with processing's default action of giving you a new and automatically named work file.In Windows an existing Processing file (.pde file) could be "opened-with" Processing. Trying to do similar in Fedora I find that I am expected to nominate an Application to open with but Processing has not installed as an application.I guess the question is how do I promote Processing to be an Application?Or is there a different approach?

Programs like matlab/octave and I'm sure many other ones allow you to start typing a command, and then hit Up to recall the last command that starts with the typed characters. Common linux shell bash doesnot do this. Is there a different shell that does? I'm not asking how to find out the last command, I'm asking if there's a shell that's a little friendlier.
