Red Hat :: Very Slow Terminal Commands In RHEL-5.4 / Scientific
Apr 8, 2010
I have a new installation of Scientific Linux, which is basically RHEL/CentOS 5.4.
Everything works fine with it, its nice to see KDE3.5 again BUT
certain commands in cli (console, konsole, xterm whatever) take an age to run. The worst offender is vim, which takes about 20 seconds to open fstab for example. Even mkdir takes about 10 seconds to run.
I am used to these type of operations being almost instantaneous, so there is obviously something wrong here, but I can't imagine what.

I have two problems. I installed a RHEL variant (scientific linux) on an already dual boot system with ubuntu and vista.
It replaced GRUB with (I think an older) GRUB version and to add to that I cannot see my ubuntu ditro anymore. is there a way of reinstalling the GRUB that came with ubuntu then adding the RHEL distro to it?
my second problem is that I cannot figure out how to enable wake on lan in scientific linux (RHEL). on ubuntu I would just write a small script and update all runlevels to run it at startup. what is the alternative on redhat?

if you do the command conky in terminal, it starts conky ofcourse, but it also shows output to that terminal so you can't do any other commands to that terminal, Is their an option like you can do with the '&' sign in other cases? If you do the '&' sign with conky it still gives output, also the conky -d command gives output...

I have installed RHEL 5 in my pc with following configuration:
RAM-2GB
Processor : Intel,Dual Core
Motherboard : Asus-MX
The problem is when I configure the network setting i.e.,Ip address, Subnet mask and default gateway, the pc becomes very slow. For opening the terminal it takes 20-25 seconds.

I know CD, Apt-Get, and Dir, but besides that I know mostly Command Prompt commands and that's not many, and they seem to differ from Terminal. What are some useful Terminal commands that I should know how to use in times or need?

I've mounted a kind of proxy to map some cifs folders, 150 aprox. It umounts and mounts everything each hour, to check on changes on a configfile managed by a secretary, she just edits a file with names and I prepared a cron to notice the new mountpoints. It's a debian, no desktop , no nothing else. Just mount.cifs and apache2 to let the master webpage access to some files on each user samba home. The server has 4 cores and 2Gb of RAM. It's brand new, but it goes very slow.
[Code]....
Does anyone have an idea why is that working so slow? The apache is working well, it's the shell which is working extremelly slow.

I'm messing around with a new install of Debian 8, trying to get a sandbox of Oracle DB 12c up and running in an ESXi environment.
open-vm-tools was giving me troubles (resizing the window didn't make the resolution change), and Oracle DB was fighting me with environmental variables.
Well, while I was troubleshooting the Oracle issue, I needed to reboot. When it came back up, I couldn't log in. When I attempt to log in using known working credentials, the screen goes black like it should, and then loads the login screen again.
I SSH into the box and try to run commands, but every single command I run returns "Command not found" including "ls" "su" "cd".
I'm able to boot into recovery mode, where the commands work under root, but I'm not sure what to fix....

I am in the process of coverting some video files to motion jpeg (Wii) files with ffmpeg (great program by the way). I have been successful and so the majority of my work is over. My question is simple (I think) but complex to me so... here it goes. Is there a way on one command line to "batch" convert 8 or 9 files together instead of one by one. I just don't know what to put on the command line. I took one UNIX class a long time ago and the terms pipe and such come to mind... but I forget. Any takers? That was I can write what I want the computer to do in the morning and just come back after work and voila...

I was following a guide to stop Ubuntu from always asking the root password. And apparently i messed something up in vsudo edit or something like that i was in... So now when i put in a sudo command i get this...
Quote:
>>> /etc/sudoers: syntax error near line 18 <<<
sudo: parse error in /etc/sudoers near line 18
sudo: no valid sudoers sources found, quitting
so i cant even get back to undo what i edited.

I've created a bash shell script, to open a few graphical programs. Trouble is, the next one doesn't start until I close the first one. How can I just skip to the next program?

I couldn't really find a general Ubuntu discussion area. So I typed ipconfig and of course it said no such command blah blah blah. What I found interesting was that it provided a list of other commands I may have meant to use, ie. ifconfig. So what's the algorithm used to determine the commands? Is it SOUNDEX or something else?

I upgraded to 11.04 today and wanted to reconfigure so that I could have the desktop cube again. Once I started trying to switch my settings for the cube configuration compiz asked whether I wanted to turn off various features and apparently among them was the control bar on the side and top of the screen. Now I log in to Ubuntu and I get my workspace and that's it. No control bars, just the workspace. I need to know a few things:
1) Has anyone else had this problem?
2) How do I get into the terminal from keyboard commands?
3) What terminal commands do I need to bring back at least the main toolbar so I can access programs.

i don't know if there is a way to check or see the list of commands available to each shell you decide to use, be it BASH,KSH, etc in your terminal. You know how its works in microsoft, in cmd-line or dos, you type HELP and its brings all the commands available for use.

Recently I gained interest in running command from the terminal, like rhythmbox-client --play-pause and vlc --open, but I could not find the vlc's pause command under vlc. there's a way I can have a terminal display the commands that run when I do some action. For example, when I click on pause in vlc, the terminal should show me what command it used to pause vlc. What's the closest ting I can get to this?

I would like to find documentation on all the available terminal commands and syntax for CentOS 5.
I have googled and looked through the wiki and found nothing about the terminal to my ability.
As for what I am referencing by commands:
sudo: I get the su means super user
cd: change directory
rm: remove, I don't know how to remove folders.
General navigation and using the terminal to create files/directories/open file editor/etc..

I'm not really new to debian. Just never encountered this before. I'm not even sure how to describe that. The first time I realized something was wrong when I tried to create a file with dd:
root@strych ~# dd if=/dev/zero of=1GFile -bs=10M count=100
dd: bad operand `-bs=10M'
I mean what, I've done that many times before! Then I noticed that some commands started to behave this way:
root@strych ~# ls --help
--help: No such file or directory
On the other hand...
root@strych ~# fish --help
fish - the friendly interactive shell
or
root@strych ~# apt-get --help
apt 0.8.6 dla i386 skompilowany Oct 4 2010 11:55:22
Usage: apt-get [options] command
apt-get [options] install
So what the hell is wrong with my shell? This is persistent with any type of access: both ssh and local (physical), it's the same when I use sh, fish, bash or whatever. It also doesn't matter which user I'm logged in with. I haven't changed .profiles or anything concerning terminal really, besides installing fish but even that was long before I realised this problem. Actually, I can't think of anything that I've done that could do this. What am I missing? The system is debian testing with kernel 2.6.32-5-686.

I'm looking for information on how to use a single FTP command from the terminal window, that would do this:
- Login (with usesrname/password)
- Set Transfer type to Binary
- Get all files in a directory and download somewhere.
- Delete all files in the directory that was just downloaded.
- Close Connection when complete.
There lots of information on individual commands, but I want to combine them into one single command that requires no human interaction. Just one big line Hopefully from this one command line I'll be able to create more for other purposes (like login and delete one file then close).

I was wondering if there was a way to show all current actions I am doing in a terminal window? For example if I left a terminal window open on one of my desktops, could I make it display everything I am doing so that when I receive some general error in a program, I could jump over and get some more details. I could also use it to see what commands are actually run when I do certain things.
