Ubuntu :: Single Tab To Complete Command?
Mar 7, 2011
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!)

For as long as i can remember, using arrows (and home/end) in a bash shell that has a command running would print some fancy ^[[A caracters and then return the prompt at the end of this.
Now this behavior has changed. Using the arrows while a command is running actually moves the cursor on the screen. When the command completes the prompt appears at the new cursor position which is kind of strange and messes the screen.
For testing, just enter "sleep 10" and during the wait move the cursor with the arrows and home/end.
How can i get back the original behavior?

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'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 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?

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?

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'm using Ubuntu 9.10. I just installed koffice (Version 1.x) which includes kformula.
Then i realized that koffice 2.x is already available which seems to be called "koffice-kde4" in the repositories... But koffice-kde4 doesn't have kformula included - where is it?
how i could install the complete koffice 2?
