How Does sed or other command edit the 1st line in a file and comments it? Meaning add "#" to the first line in a file for example?

I don't think it's very necessary to mention my hardware to get an answer to this question.I found out about the Cairo-Dock and fell in love with it. It annoys the hell out of me to have to start it every time I boot. I navigate to- System> Preferences> Startup ApplicationsUnder the startup programs tab I click on add... Now what??? Put the name as Cairo... what about the command. I don't know what file to navigate to.
View 3 Replies View RelatedI have a fairly long list of data that I am trying to put into a math program (maple) but before I can do that I need to edit the format of the data such that at the end of every 25th line I add a comma. I would prefer a solution that uses vi, but if that's impossible sed would be fine also (or awk).
View 6 Replies View RelatedI am looking at how to add particular text to a file in bash.Here is what I am trying to do:In the /etc/grub.conf file, I am trying to add "audit=1" (without the quotes) to the end of the kernel line...such as:kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/1 rhgb quiet audit=1
As there are a few different lines in this file, I am only looking to add the "audit=1" to the above line via a bash script.
I wish to add information to one of my files based on matching IDs,
Here is an example
(the id is the 3 colunm)
(the ID is the 2 colunm)
And the output i wish to be
OUTPUT:
So as you can see the ones that do not match are still present, and the ones that do match just have the extra information from file2.txt added to them.
I thought about using join but that only seems to join the ones that match displays thoes only. i would like all the information in the output file.
Couple of days I go I setup VLC using Kubuntu's graphic software manager, and installed the 3 plug-ins, one of which was related to pulse. After doing this sound stopped working in flash videos. I had read, not sure where, that Kubuntu didn't use pulse (which slipped my mind when setting up VLC).
So I make the mistake of removing everything which had pulse in it's name (again, via the graphic software manager). A message popped-up saying that some packages needed to be removed/edited (a LONG list, a big clue that I was doing something stupid I guess). I let it run it's course and after that it won't boot properly.
If I boot it normally it hangs at the Kubuntu screen with the five dots filling endlessly. If I press F1 it's stuck at "checking battery status."
Recovery mode boots, but the recovery option does nothing.
So I was wondering if I could boot into recovery mode and go into the terminal and add a live USB as a repository for apt, and try to salvage the install?
Or should I admit defeat and reinstall?

I tried to change the basic toolbar to cairo dock,a tutorial that i found told me to write in terminal gksu gedit /etc/apt/sources.list.d/winehq.listso i write it and a window opened,i couled not find the text that told me(the tutorial i mean)so i closed the window,after that i keep taiking the same error
E: Type �sudo� is not known on line 55 in source list /etc/apt/sources.list
E: The list of sources could not be read.
Go to the repository dialogue to correct the problem.
E: _cache->open() failed, please report.
now whene i got in the winehq.list the text has gone and i take this error in update manager,my software center doesn't work and my terminal whenever i type sudo commands says
E: Type �sudo� is not known on line 55 in source list /etc/apt/sources.list
I get this error message: E: Malformed line 57 in source list /etc/apt/sources.list (dist parse)

Here is the sources list (??) as well
don't know much, but when I tried to update I get this error:
E: Type 'sudo' is not known on line 52 in source list /etc/apt/sources.list E: The list of sources could not be read.
There is a problem with my source list (apparently) I'm running 11.04 if that helps.When I try to use apt-get install update for example, I get: "Malformed line 59 in source list etc/apt/sources.list"The same error occurs when trying to access synaptic package manager, it tells me there is a malformed line and the list of sources cannot be read.This error prevents me from apt-getting anything, updating and i suspect it is affecting the software center too.

I'm trying to make another file annotation script a little speedier than it has been by the up-until-now proven method of checking the last four characters in a filename before the "dot" (eg .jpg, .psd) against a list of known IPTC categories and Exiv2 command files. It occurred to me that if one script generated a list of files in directory foo, and the same or another script sorted that list by that four-letter tag,then that list could be used(instead of a for/do/done loop on the real files in the folder) by the command-file-matching script to "vomit out" which annotator file would go with file nastynewfile.jpg, f'r'instance. The script I had been using for this task looks like this:
Code:
while read 'line';
do
sp=$(echo $line)
vc=$(echo $sp | cut -d"," -f1)
cv=$(echo $sp | cut -d"," -f2)

Where I seem to be stuck is with how to sort the lines in templist, which may be any number of different lengths, from back to front. sort -k looked promising, except it seems only to work the other way round. I thought of invoking a
Code:
q=$(expr length $line); echo $q
n=$[q-8]; echo $n
kind of thing, but that presented the problems of how to sort by those, how to tell sort where to find them (grep?) and how to "stitch them back in" to the original list, which is what I want to sort in the first place.
got a situation where if i process a command i get a numeric output something like below:
for example:
# cat example.txt
856589
856470
987866
656658
876897
now i want to see this output in single line like below:
856589 856470 987866 656658 876897
how do i get this?
I have two files (not sorted) and need to compare line by line (i.e. first line of file1 to be compared to all the lines of file2 and so as for the rest of file1). Output will be an array of length of file2. Any suggestion in BASH other than a grep inside two read line loops ( which is time consuming for files ~1000s of lines).

I have some basic experiencing creating simple scripts/making directories/changing permissions/etc. but I'm stumped on this one.
I have two linux boxes. I have a script set up on box 'A' to SCP into box 'B', grab a copy of a database backup and store it on box 'A'. It looks like this:
scp root@X.X.X.X:/blah/blah/blah/dump.23.gz /home/blah/DB_Backups/
I have generated a public key on box 'A' and placed it into the authorized_keys file on box 'B', so a password is not required and the file copies over successfully when the script is run. On to my problem...
I need to know what date the 'dump.23.gz' file was originally created when I'm viewing it after it's been copied to box 'A'. If I ls -l on box 'A' it only shows me the date it was created on box 'A' when it was copied.
What would I need to add to my script to append the backup's original creation date on box 'B' to the filename so that when it gets copied to box 'A' I know when the backup was created on box 'B'. I'm sure this is probably confusing. I've done lots of searching and can only find information on how to append the current date and time to a file name. I need to append it's original creation timestamp to the filename when it copies over.
I have been able to successfully build a live Linux CD, the problem is during the course of setting up my new linux instance on my latop I had to install a few items (intel drivers). So got all the files and everything worked after manually installing, but wanted to try to rebuild the CD with all the files in the CD, rather than having to use a USB drive to put the file onto my laptop. When I made the changes to the configuration that I previously used(just edited the chroot file and did lh_build again) nothing happened the binary was no rebuilt. So some questions: If I am wanting to add files into a live CD build how do I do this? How do I rebuild a CD? or Is it possible? (i.e. I have to continually start from scratch each time).

I just purchased openSUSE 11.2 x64 on DVD from osdisc.com, as well as the 5 x64 repository DVD's. The base install went fine, but when I try to add thos's to my software repositories using yast they all have the same listed name, "repository" - I can change that to show "repository disk 1" etc, but when I go to install stuff and the software installer asks for "repository disk 1" I put that in the dvd drive, and it cannot recognise it, spits it out and asks for the same disk again...hmmmm. Should I not change the default name that comes up when each DVD is added to the list? If I leave them unchanged will I be told which is the correct disk to insert, remembering that in the list they all have the same name
