I have recently installed Ubuntu 10.10 Server onto a old PC. Everything seems to be working fine except that i can't tab the next command.Like when you are typingcd hom (Then you press tab and the 'e' appears.)When i double click tab I get a list of all the possible directories but I wont seem to work when I press it one time just to complete my command.Anyone got a clue how to fix this?(I am new to this community but I got to say i Love it. We use Ubuntu at our university and it rocks!)
I went to a help site because I wanted to install an IRC client named seamonkey. I followed the directions step by step, copy and pasting each and every command into my terminal command line as per the instructions. Every single command produced an error. Needless to say, I was unable to install it. What's even more frustrating is I can't even post the url for the site here so someone can see what commands I was using.
I've been searching high and low for a solution to my problem, and have not had much luck as to yet!The situation is: I have two files containing bits of info that both need to be included in a single command, such as a for loop, but as separate elements. What I need to do is basically this:Code:ssh <servers in list a> ls -la | grep <items in list b>Does anyone have any thoughts on how I might do this? Is it possible to do using bash scripting alone?
I wish to allow a user to use sudo to run a single command (service app status) to determine if my application app is running, in my sudoers file i have: user ALL= /sbin/service app status I understand that there is a parameter called timestamp_timeout that will set the timeout for the 'user', but requires at least 1 entry of the root password.
I wish to allow the user to do "sudo service app status" and not have to enter the root password ever(maybe once is ok), but still make the user enter the root password for all other root activities. Is there a way to prevent the password entry for this command only and no others?
i have 30 linux PCs running. i need to check the performance of all pcs( memory,ram and process usage) in single command or in GUI mode.In solaris we have perf script to check performance in GUI mode. i need same type in linux?
I'd like to copy a file, say widgets/water.txt, to all subfolders in the folder widgets using a single command. So if the folder widgets has 10 subfolders like widgets/blue, widgets/green, etc. I'd like to copy water.txt to all of them with one command.
I tried the commands
Code:
cp water.txt ./*/water.txt cp water.txt ./*/
However these don't seem to work. The latter gives 'cp: omitting directory' errors.
I have 10 files of .dat formatsayA MCDR .datB MCDR .datand so one upto 10 dat filehow i convert these 10 dat files to txt files using single command or script
I want to watch a number of processes in "D" status repeatedly with following command:Code:# watch -n 1 'top -b -n 1 | awk '{if ($8 == "D") {print; count++} } END {print count}''but it didn't work. I also tried with double quote. Can I use 'watch' command is this case?PS: I know 'while' and 'sleep' can do the same but it is dirty workaround.
I am trying to write a very simple script that will go to every subdirectory of a single directory and run a command (lets call it make_ndx).I know I can write this the long way with in a text document with something like:
cd /"the directory"/"the 1st subdirectory" make_ndx cd .. cd "the 2nd subdirectory" cd ..
Alternatively, I also tried: for i in 'find /path/somemorepath -type d -mindepth 1'; do cd $i; make_ndx -f *.gro; done which returns me with the error cd: find: no such file or directory. But if I run the find command by itself to test if I am calling the right directories, it gives me the exactly the output I am looking for. Any ideas? Should I just write the find results to a file and loop through the contents of the file (which seems a little bit like overkill) or am I just making a simple typographical mistake and I am just not seeing it?
I increase my knowledge in vim in two ways. Little hints about doing this or that and scattered studies using the vim help files. Please do not believe I always rely on the first one.
I am using SLES10 and i checked with command crontab -l and when i compared it with the cron.d/daily/monthly/hourly , all they are different. is there any single command that list out all the cronjobs that exist under the system.
Have this script which is reading in a series of files, one at a time with while-do-done loop, each file goes through various greps/awk's where this info is then saved to various files for later use. i.e....
Script is being run on Linux Red Hat,
In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)
i.e. (example from above)
Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?
I have question about the UNIX sockets. my goal is to connect multiple sockets from a single client to a single server and keep them open...I'm not sure if that is possible to create or not. Do you have any suggestion or an example of code?
How to copy a Read-Only file in Linux and make the copy writable with a single cp command in Linux (Ubuntu 10.04)? The --no-preserve and --preserve seemed to be good candidates, except that they should "and" the mode flags, while what I am looking for is something that will "or" them (add +w mode).
More details: I have to import a repository from GIT to Perforce. I want that all Perforce depot files are Read-Only (that is how Perforce was designed), while all other files that were derived/copied from depot files are writable. Currently if a Makefile tries to copy a Read-Only file then the derived file will also be Read-only. This leads to build-errors when cp tries to overwrite Read-Only file second time. Of course the --force is a workaround here but then the derived file is also Read-Only. Also I do not want to mess with "chmod" after each "cp" command - I will do that only as the last resort.
i disabled the gdm from RC start-up scripts so now my ubuntu will boot only in text-mode (terminal) ,but what i need to know is how can i run a single application for ex. Firefox in gui mode ,by keeping gdm disabled ,i tried using startx but it did not solved my issue .
I'm trying to rip a bunch of DVDs to my HTPC. I'm a bit of a quality fiend, and since I have 2TB of hard drive space, I want to rip straight to raw VOB files (that, and it's WAY faster than transcoding). So far, I've tried several methods:
vobcopy -l -t movie
This DOES create a single file. However, when it is played, the seek is limited to the length of the first VOB file. For instance, one of my movies starts with an 8 second VOB followed by 4 other larger files. When playing, I can only seek within that 8 seconds.
dvdcopy and cat/mpgcat/vobcat
Same issues. Using cat gives seeking issues - limited to the first VOB's length. mpgcat complains that the audio tracks of each VOBs on the disc are of different bitrates, and I have to force the rip. The completed file once again has seek issues.
I'd LIKE to do this from the command line. Also, I am actually ripping ISOs. I originally ripped my DVDs to my drive as complete images, but now I just want the main feature. So, if you have any better ideas with dealing with the raw files, that would be better.
Is there a way that I can have a user on my Ubuntu 11 box that when logged in it automatically opens X program and nothing else, no window manager nothing, single program for that user only?Here is the scenario, I have 3 users, one is called Skype. I want when someone logs into the skype user no window manager at all be available to that user from the GDM and for xwin to automatically start skype up.
I've seen a lot of documents which use a really beautiful font. This is an example:[url] I mean the font which is used for "Problems", 'The area of a regular...'. Well, I found out that it's somehow called TeX font and I tried to download it. Unfortunately, this is font is separated in many, many files (Italic, Bold, Standard, Italic Bold, Math symbols, other symbols ...). It's horrible, because I would just like to use that font in OpenOffice. I wouldn't like to still change the style by choosing another font. Is there a place where I can download the combined TTF file? So I would just have the bold, italic, math symbols and other symbols in one font without having to choose the different one to just change a style or to enter a copyright sign?
I have configured squid in a single PC to save bandwidth and to block some sites.It works fine,but the only drawback is if the user disables the proxy settings in the browser they can able to browse all sites..Is there anyway to force all my browsers to go through proxy??
I have an Ubuntu install on an 8Gb SDHC Card, customized for my Toshiba NB205. It took quite a bit to get sound and BT working, but now it's fine. Just out of curiousity, I used this same SDHC Card to boot my Dell D610 -- it booted, and sound and WiFi worked fine. I was surprised. There was a single error message after the desktop appeared, but I didn't record it.
I am now wondering: is it practical to use a single USB installation with multiple devices? I can imagine a number of complications, but was surprised that my attempt worked on two very different hardware platforms. There was discussion, when pendrives first appeared, of being able to use one to boot any PC to your own USB-based OS, bypassing any other OS installed on the PC.
