Ubuntu :: Every Single Command Produces An Error
Apr 15, 2010
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 am using Ubuntu 9.04 Server. I use screen alot for persistant sessions and suddenly I have a problem. When I type Code: screen -R -DD as usual, I get into screen but there is no command prompt. There is a cursor and I can type commands which work, eg ls. However I don't know which directory I am in, so it makes using it rather hard.

My question is, am I going to have issues on reboot, and if so, is there anything I can do to prevent them?

Suse 11.3 KDE 32bit Following instructions in software.opensuse.org: Search Results I installed LibreOffice using the 1-click Install method. It will not start and produces no error when invoked from the console. Now here's the strangest part. If I left click on an .ods file produced by LibreOffice on another computer (on which it worked) KDE tries to extract it using ark even though file properties identifies it as an "ODS spreadsheet".

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?

i found in some thread that Swap space wasnt really necessary for RAM of over 1 GB, and true to it, i wasnt using using much of my 4GB allocated for swap ever so i deleted it ( dunno if it was wise, but didnt face any problems when i first deleted). today, i found out from another thread on a way to extend the size of /home directory if it was on a seperate mountpoint, and if space was available on my hard disk.
i just had 1 GB allocated to home directory and it used to fill up quite rapidly (due to cache from google chrome). I made a backup of my home directory contents, and i deleted the /home partition through the Disk utility. Somehow i couldnt combine the two unallocated spaces under a single partition why is that? (My plan was to combine that 1GB and the 4GB from the earlier swap space to use a 5GB home partition.) then i restarted and ever since i have been seeing the Grub error,and am not able to access my operating systems normally. GRUB Loading stage 1.5 Grub loading, please wait Error 15 . i am attaching the results.txt from my system obtained by booting through a liveCD. Something tells me that the way ive been following has been a roundabout one or a very inefficient one. how can i restore my system to normalcy

I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
My system:
Intel i7
Ubuntu 10.10 Maverick Meerkat
android-sdk-linux-x86
eclipse 3.6.2

I have a single boot system that was working great until this morning when it locked up. I was working as I always do when the system stopped responding completely. CTRL+F1 did not work to allow me into the back so I could log in and see what was happening.
CTRL+SHIFT+SysRq did not recover the system or interrupt what ever was causing the lock up.
SSH from another system failed as the client did not respond
So I had to do a hard boot and when I did I got this:
GRUB Loading stage1.5.
GRUB loading, please wait...
Error 17
Again this is a single boot system no Windows other than in VMWare inside the install. It is a multi drive with RAID set up workstation that I have at work. The short of it I am sole IT support as our companies ITS will not support Linux. In 5 years of operations with Linux at work this is my first issue, and I can't figure it out. I already tried the PartedMagic solution (ref = Re-Install Grub Quickly with Parted Magic) and that didn't work.
I re-installed the system completely even going to the extent to change my partition scheme just to make sure that wasn't the problem (which doesn't make sense as the system had been running for 46 days non-stop without a problem). Upon reboot after performing a complete security update I got the Error 17 message again.
Below is the output of fdisk -l
Code:
Welcome - Parted Magic (Linux 2.6.30.6-pmagic)
Most of the filesystem tools and partition programs featured by Parted Magic include man pages. To read a manual page, simply type man and the name of the tool. (Examples: 'man ntfsprogs' or 'man fdisk')
