I have a large text file and I have some comment lines in it beginning with $.
Now here is the challenge there are some lines where there is actually a written comment after $ (with some blanks between)
Then there are lines with only $ on it - with maybe some trailing spaces.
I would like to delete these dummy lines...
Lets say from
$ This is valid comment
$
$
$

How do yo find a pattern with sed or awk and then:
- add a # at the beginning of the line containing it
- and add a # at the beginning of the following 2 lines, too?
Say, I want to comment out the line containing "which 0launch" and the two lines following it:
if [ -x "`which 0launch`" ]; then
exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
fi
Expected result:
#if [ -x "`which 0launch`" ]; then
# exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
#fi
I need this because I do not want to comment out every line containing "fi", just the "fi" of this specific if statement.
I'm planning to partition a new hard drive to dual-boot Mint+Mepis. I've read partitioning tutorials and posts, and want to check my understanding--I'd appreciate input from an experienced person.For 500GB hard drive, dual-boot Mint+Mepis:
--Mint: / root partition for OS; /home partition for ease of upgrading
--Mepis: same as Mint
= four partitions
And:
/swap partition to be shared between Mint+Mepis
/shared partition for shared data
= two partitions
Total = six partitions
Since four primary partitions are allowed, I should use three primary partitions and one extended partition containing three logical partitions.Is that correct?If so, what should go where? I assume there's an optimal strategy--Should each /root of Mint+Mepis go in a primary? What should go in the other primary, and in the three logicals? Or maybe I don't need three primaries?--use two primaries and four logicals?
I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)

I have this massive table file with some data in it and I want to replace some lines that are wrong with the correct ones that are in another table file of the same format. The wrong lines are not all together in a block but randomly distributed so I need to make a loop checking if the line is in the other file and if it is, replace it.

View 4 Replies View RelatedI recently installed F15 on my laptop. Earlier today I updated a little bit more than 500 different things, and then rebooted. Upon seeing the GRUB menu, I saw that one of the updates added a newer menu entry for Fedora- the newer one's version was a fraction higher than the older menu entry.Anyways, is it safe for me to comment out the old entry in /boot/grub/menu.lst?

Most of the forum and blog post I found on the subject suggested different programs, Common for these though, is that they don't do annotations in the pdf, but rather import the pdf as a background for writing on top and then saving your notes separately. This have to problems:
1. You can't comment a pdf and mail it to your co worker.
2. You can't switch between programs freely...
As far as I know the pdf format has capabilities for annotations/comments. So anybody know how to take advantage of this, for note taking? My use for this would mostly be notes on slides during lectures etc.

This n00b is having a weird situation during dist-upgrades that I've never seen before. It's puzzling my more-experienced pals in an irc channel, too.
Sometimes--not every time--while running a dist-upgrade outside of X on my Debian Testing machines, I get an informational text display (a comment box?) that always ends with the text "(END)". The display freezes there, and I am given no opportunity to respond and let the upgrade procedure continue.[URL]..
I've tried pressing escape, the space bar, enter, arrow-keys... nothing changes (I get system beeps with each keystroke). If I Cmd+C, I get a root prompt back, but any characters I type are not displayed as I type them. For example, I can type # "shutdown -r now", and the machine will shutdown --but the characters are not displayed as I type them.
If I immediately restart, go into a regular X session, and run synaptic, I get the same comment--but in a window with a "Close" button that I can click. The upgrade will then continue [URL].. This has happened on at least 3 different boxes, all running debian testing. Under gnome and xfce... Probably with 4 different packages in the last 3 weeks?
This morning it happened on a new debian testing install, and just now it happened -- with the identical package -- on an older debian testing install on a different box.[URl]..

I agree that this is a problem in making every NTFS partition a boot selection option in your grub menu.lst file during the installation of openSUSE. Someone should consider asking help from please_try_again in the openSUSE forums on how to find a bootable Windows partition and add that fuction to the openSUSE installer. Here is a pointer to the findgrub article here.
Looking for Grub and Windows bootloader in all partitions.The basic situation is that there is normally is only ONE booting copy of Windows, so why would you create three or four menu entries due to the number of NTFS partitions found on a hard drive? Finally, just as indicated by Jean-Daniel Dodin, If one of those partitions in the restore partition and a user boots it, it could be all over for the user copy of Windows, for the openSUSE install and for ever getting this user to try openSUSE again.
I'm trying to clear a bit of space in my overstuffed filing cabinet by scanning all my bank statements, credit card statements, insurance, important post etc. into my computer.
I've been looking for a very simple document management system, where I can record the category (bank statement etc.) date, comment, etc.
I don't want to make these accessible via the internet and I really don't want to hand them all to Mr. Google, via googledocs, because he already has enough info about me without reading my bank statements.
I have a file with n number of lines where every 2 lines are grouped.
So I want to print the items in a line and the next line in a single line.
For example:
I can print the line and the adjacent together and print the required items like this:
But that's not the order I want. How can I get it printed like below:
when I run the following command:
awk -F, '{print $10 "," $5 "," $1 "," $3 "," $4 "}' myfile > tmpfile
tmpfile displays the lines but they are all cut off and placed on the line below at the same point.

I have a file with a random word on each line (3k+ lines). How can I get the lines with only five characters? I tried using grep file | more, but it returns all the words (even those less than 5 characters).
Edit: I also tried grep '.{5}' file | more but it doesn't show anything. And grep '.{5}' file | more returns all lines with four or more characters (I'm really confused about why it's doing this).
