Ubuntu :: Can't Get The Variable "type" To Add The Line When Its Selected?
Jul 9, 2010
with my "if" statement? It's probably just a bracket or something stupid missing, but I cant get the variable "type" to add the line when its selected:
clear
read -p "Please Enter Printer Name : " name
read -p "Please Enter Printer IP : " IP
read -p "Please Enter Printer Description : " des
read -p "Please Enter Printer Location : " loc
read -p "Please Enter Printer Class : " clas

I'm not that familiar with sed and awk in order to be able to solve this problem on my own, so I'm calling on you for a bit of assistance. I'm writing a Nagios plugin to check our Oracle tablespaces and the output is given in one line like this: 1.04007771 TEMP 0 UNDOTBS1 .005340579 USERS 0 7 rows selected. I've been playing around with sed like below to delete the obsolete info and change every second space into a newline:
[code]...
how many tablespaces there are so I'd have to check all databases and 'hardcode' the tablespaces in my script. Is there any way to 'automate' this knowing that 'rows selected' preceded by a number is always the last line and using a sort of counter to auto-adjust the number to put in the -e 's/ / /2' part?

I have a multi-user machine with several network interfaces (Ethernet, if that matters). I wish to grant selected users, or groups, full access to selected network interfaces (including ability to adjust IP address and to bind to low ports, but *only* on those interfaces). It is important to me that an user/group does not such full control over other interfaces. Granting partial, or temporary, root permissions is OK; it's a friendly environment.How do I go about it?System: Linux 2.6.recent; usual Debian setup (can be adjusted if needed).

I want to replace a certain line of a file, my bash script looks like:
#!/bin/sh
sentence="if [ -e /home/inf/Download/$playlist ]"
sed '4c
$sentence' oldfile > newfile
mv -f newfile oldfile
But the variable $sentence can not be identified in ' ' . And also you can see I just want to update the old file. But the sed command can not save the file for me ,so I need to write them to a new file and over write the new file .

I want to get the last term of an unknown-sized text line, by usig the awk command. Is there any variable which points to the last term of a text line ? (obviously, y can obtain that term if i knew how many terms does the line have... i.e. awk '{print $12}' ; if we are talking about a 12-terms text line) I wonder if there is an option like $?, to get the last term.

I created the following.
x="top
middle
bottom"
I would like to make the following work.
while read line
do
echo $line
done
instead of importing a file I would like to use the variable $x I tried using pipes, but with no luck. My goal is to read one line at a time, but not have to export my data to another file, I would like to keep it all within one script.

I'm using sed to remove certain line in a text file based on a match with 2 variables from input. Here is how it looks like in file
Philip S:Odds:45:343
Mike Junior:Odds:3:56
I prompt for 2 inputs in variable form which is compared to the first 2 fields of the above text (: seperated). So say i enter Philip S and Odds then it should delete the entire first line.

To hide the user input to be displayed on screen, use the terminal line setting command stty -echo, whatever the user enters after this command will not be displayed in the screen. to make the input characters get displayed on the screen use stty echo.

I have added an application launcher to my desktop and it works fine. However, I want to be able to feed parameters to the launcher before I launch the application. So, for instance, if the command is normally "/usr/bin/foo something" I want to be able to add the "something" parameter dynamically after clicking the launcher but before the application launches. Is this possible in Fedora?

I'm having a problem updating or even running the software center. Each time I open either of them, I get an error stating "'E:Type 'ntu-wine/ppa/ubuntu' is not known on line 1 in source list /etc/apt/sources.list.d/ubuntu-wine-ppa-natty.list'" and the update manager or software center closes. This has just been happening a few days ago and I would like a fix for it. I'm using 11.04 beta 1 and my WINE version is the latest development release. Anyone know how to fix this error? I tried unchecking my WINE PPAs in sources but that don't seem to do any good.

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive
