I have a file like this code...
I would like to use sed or similar to remove everything before the period, but only for the lines 1 and 3 (or lines with a-z.a-z and not a-z = 0-9.0-9.0-9.0-9)
I found a way to do this using:
cat $file | sed 's/[.].*//'
But this 1)remove all the text AFTER the period and not before it, and 2) removes everything after the first decimal of the IP address.
I am using Ubuntu 9.10 in U.S. English with a German keyboard layout. Accordingly, pressing the delete button on the numeric keypad will produce a comma, which most applications do not recognize as a decimal. in order to have the key produce a period.
I have tried editing the /usr/share/X11/xkb/symbols/de and changing the line
Code:
include "kpdl(comma)"
in the "basic" section of the file to
Code:
include "kpdl(period)"
which seemed like the perfect solution, but upon restarting an error message pops up and the keyboard layout is changed to U.S. English.
Code:
cd /usr/share/X11/xkb/symbols
xkbcomp -lhlpR '*' -o ../symbols.dir
which does nothing at all if used with sudo and produces an error message if used without. Reverting changes to /usr/share/X11/xkb/symbols/de removes all errors.
Is there something else I need to do to have xkb accept my changes to the file?
Code:
include "kpdl(comma)"
does not specify a symbol to be mapped to the keypad delete key, but rather constitutes a command that integrates a pre-specified option into the layout file. Thus, simply removing the line works perfectly well, even without using the above suggestion to register the change to the file with xkb (or whatever it does).
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
View 3 Replies View RelatedThrough various Windows reinstalls and switches within Linux distros, I have a massive amount of duplication within my music archive (on the order of 7+ dupes of each file). Now, I found a lovely program called "fdupes" and was able to build a list of all the duplicate files, and I'm trying to use "xargs" to remove then. However, when I try and run the command "xargs -0 --arg-file="dupes.txt" rm" or "xargs -0 rm < "dupes.txt"" it give me the following error: "xargs: argument line too long".
how perhaps a different way of accomplishing the same thing?
Having recently looked at my monitor property using <Preferences> <Monitors> I now have a small pink rectangular graphic at the top left corner of my screen which hides the first part of the launch panel, as well as the main controls on any window placed in this position.
This graphic is identical in colour and content to that presented by the <Monitors Preferences> app. How do I delete it? It's not click-able drag-able or editable. It doesn't even appear to be a window.
What i want to do is pretty simple.I want to uncomment every line that begins with "deb" (except for deb cdrom) in /etc/apt/sources.list.I know how to do this through system > administration > software sources.I know I can gksu gedit /etc/apt/sources.list.I'd rather not do it that way.I'd rather have a script do it. It's less work, less typing, less clicking, and would work the same on every ubuntu version.

View 4 Replies View RelatedWe had seen some time ago, various tricks to remove the character MS-DOS text files on Linux. Here is a new trick to do this directly from the vim editor.

I need to chop of the top 30ish lines of several log files until a line starting with "Initialization completed."The trouble is that it's not always the same amount of lines that need to be deleted, and they don't always contain the same information, which is why I would need to delete everything priorhe line starting with "Initialization completed."Right now I have a little script I wrote based on looping each file through several "grep -v" commands with each known pattern of lines I want to ignore, but it is tedious and I have to inspect each file afterwards to make sure nothing is left from above "Initialization completed
View 3 Replies View RelatedI have a series of file names in a text file that I generated by running
Code:
bash-4.1# ls -alt *.txz | awk '{print $8}'
and then copy pasting the output. All of these file names have the version number
Quote:
-4.4.1-x86_64-1alien.txz
I just want a method to remove that version number from all the filenames so that I can then add all the packages without version numbers to a blacklist file.
I've tried kwrite and mousepad and both have a search feature and a replace feature but I haven't been able to just have the text removed successfully.
I am trying to create a shell script, on taking a input file as parameter, which need to do 3 things
1) create a copy of existing file.
2) add a new line to the copied file.
3) strip off all the absolute paths inside the copied file
The first 2 points are straight forward. but i am finding it difficult to acheive the 3rd point. myself not very good with awk and sed. but gave it a shot in vain. For example, the input script consists of below,
PROGRAM=`/usr/bin/basename $0`
HOST=`/usr/bin/uname -n`
echo Start $PROGRAM `/usr/bin/date` |
/usr/bin/tee -a $LOG
The output of the script should look like,
PROGRAM=`basename $0`
HOST=`uname -n`
echo Start $PROGRAM `date` |
tee -a $LOG
Was wondering if any perl guru's could help me with a quick log file adjustment. I have a text file that looks like so (tabs and newlines are revealed so you can see what separates the data):
There are maybe 100 lines of text in this file at any given time. I need to delete all duplicate lines only looking at the first bit of text prior to the first tab. It doesn't matter which one gets deleted as long as there are no two lines that begin with that same text at the beginning before the first tab. So in this example, either the fist line "1234" or the last line "1234" would need to be deleted. I already have code in my script that opens the files - I just need the code to read the text into an array and the part that would find matches based on the above criteria, and make the deletions.
If it would be easier, I can even do a system call and use SED (v4.1.5) and/or AWK (3.1.5) instead.
i want to find a command line way to edit a text file to delete all commas in the file. i do not want to replace them w/ anything.

View 3 Replies View RelatedI've been trying to figure out a strange DHCP problem my girlfriend's having: She can only get (or renew) a DHCP lease once; Subsequent tries timeout. I tried switching from network-manager (which uses dhclient) to wicd (dhcpcd), and noticed a key difference: With wicd, restarting helps (again, works once, then another restart is required). With network-manager, I haven't been able to get another lease, period.
Exploring the dhcpcd case further, I found that suspend/hibernate do not correct the issue; a full restart is required. Neither does `/etc/init.d/wicd restart` help. I don't remember if I tried killing dhcpcd; I'll have to test that. The current workaround is to restart the computer after each disconnect. It's pretty annoying, though, so I'd like to try to collect enough specifics to file accurate bug reports for each dhcpcd and dhclient. Is anyone familiar with these projects? Are these known issues? Any ideas how to hone in a bit? My gut tells me there's some state somewhere that needs to get flushed.

I skipped over Jaunty on my main desktop because Intrepid had been working perfectly for so long. Finally took the plunge to Karmic, and have had major instability problems. I cannot trace them to any particular program I am using. At first it seemed related to power management, since it would lock up every time it had a period of extended inactivity. I have disabled ACPI in my BIOS (I think), and any power management settings I could find in gnome to try to troubleshoot. That seems to have helped, but it still happens semi-regularly, sometimes when I am in the middle of using it. I have tried checking logs and googled anything that seemed important. ie a message in kern.log reads: Clocksource tsc unstable
View 2 Replies View RelatedI'm not sure if this belongs in the Server or Networking section of the forums. Anyway, last month I upgraded my server to Ubuntu 10.04 LTS. Since then, I've had a recurring problem wherein after a certain period of time, the server stops accepting network connections. Ubuntu 10 will continue to reject network connections until someone logs into the server locally, after which time network connectivity is restored and the cycle begins anew. Essentially, the server goes into a "half sleep mode". I say half because the computer is still on and the fans are running.
I've done some searching around various forms and initially figured this issue was related to problems with the Network Manager service (https://bugs.launchpad.net/ubuntu/lu...er/+bug/524454), so I removed the service altogether. However, this problem is still occurring.
I've poured over /var/log/messages and /var/log/syslog, but have noticed no irregular behavior. Has anyone else experienced this issues? I'd rather not resort to downgrading back to Gusty Gibbon if I can help it.
I am happy to provide more information if its needed

During my upgrade this fine afternoon, my system went into screensaver mode and would not bring up the security window. The window would flash for a very brief period and then disappear. I tried to enter the password to no avail. After 10 minutes of this, I gulped and re-booted. It seems to boot ok, but just like in the install, the login security window flashes and disappers. I have tried to type in the data with no luck. Does anyone have a work around? I am currently using my knoppix live disk until I can burn a deb live disk.
