General :: Using Vim To Add Something To End Of Series Of Lines
May 15, 2011
I would like to use VIM to add something to the end of a series of lines. Ideally I could do something like add " X" (with a space before the X) to the end of lines 1-40 and 50-60 in a single command, i.e. ideally I could have a break in between where I didn't add something. If that's not possible just adding to 1-40 and 50-60 separately would work too. I would be using bufdo to do this, but my understanding is that anything you can do in vim you can use with the bufdo command.

I have a problem with the latest Fedora. Installed it cleanly on a machine with Gigabyte H55M-S2 with Intel Core i3. There seems to be no sound and I checked to see if anything is muted but is not. The manual says that the sound chip is ALC888B so this could be the first problem. Any ide how I can make it work? Here is a dump of some things on my system.
Code: [weaz ~]$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
[weaz ~]$ uname -a
Linux EarthwormJim 2.6.35.6-48.fc14.i686 #1 SMP Fri Oct 22 15:34:36 UTC 2010 i686 i686 i386 GNU/Linux

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 been experiencing a problem where the screen loads and after initial first few lines breaks up into multiple repetitions of lines. Reloading helps but has to be repeated when pageing down. Mail is no problem; it is supplied by my network provider. OS is openSUSE 11.2 which I update when advised. Below is a sample from the error console:

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. I want to try and do it with sed or awk but I don't really know how to....

I am very new to Linux and trying to learn the shell scripting. Just to know is there any client in linux which does the same task as FTPS on windows. FTPS on windows can read series of FTP command from a txt file and execute them. Is there any way to do that same task, i mean reading series of ftp commands from a txt file, on linux suing shell or perl (any module)?

I've been doing some security testing in a lab environment that does not have direct internet access. From home to connect to my lab machine, I
1. SSH to machineA.
2. SSH from machineA to machineB
where machineB is my actual lab machine. neither machineA or machineB allow anything other than SSH, and machineB is only accessible from machineA. However, I really need to run yum on machineB.I have managed to get internet access via Firefox on machineB by creating a series of SOCKS proxy via SSH.
1. machineB: ssh -L 12345:localhost:12345 user@machineA
2. machineA: ssh -D 12345 user@machineC
3. machineB: configure firefox to use socks proxy, localhost, 12345
where machineC has internet without limits placed. This is the only way I have managed to get internet working. I tried using ssh -L all the way from machineB->machineA->machineC but it didn't work (even when setting Firefox to use http proxy). I tried using ssh -D all the way, but again that doesn't work either. I do have access via Firefox using socks proxy. However, yum update fails to retrieve mirror list, and from what I have found I don't believe yum supports socks proxy directly. Instead, it uses http_proxy / ftp_proxy.how to get yum to go out over the SOCKS proxy I created (same one using in Firefox)? It seems like since Firefox can access the internet and everything without issues, i should be able to get yum to tunnel through the same connection to access everything.... I tried
>export http_proxy="http://localhost:12345"
(yum.conf) proxy="http://localhost:12345"

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).

Is there a nifty awk/sed one-liner to do this operation?

I've cross compiled busybox with buildroot for the mini2440 (configured: arm920t EABI) I compiled it dynamically. I use Ubuntu 9.10 on my build system. Doing the "ls -l"-command in the /bin directory I see that busybox is marked red. (This is still on my build system, not on my target system!) The background of the word busybox is marked red. And the word busybox is in default colour instead of yellow, even though all permissions have the executable sign. I was wondering what this means. Also whether it's a bad thing? Also could this mean this is why my mini2440 will not boot correctly after transferring this root file system? (It stops the booting process just after loading the root file system)

We can see that sed just deletes the first three lines. How "seq 10 | sed -e '1,2d' -e '1,2d'"works?

In GUI style editors, you can generally select multiple lines, press tab a few times to move all the lines across (or shift-tab to go back). I have no idea how to do this in VIM.I googled around and couldn't find any straight answer to I came here.

Silly question here. My crontab looks like this:
Quote:
0 22 * * * /usr/sbin/logrotate /var/log/VRTSralus/VRTSralus.logrotate
#0-59/10 * * * * /root/memmon.sh >> /var/log/memmon.txt
0 8 * * 1 /root/SHC.sh
#0 21 * * * /root/scripts/ralus_restart.sh > /dev/null 2>&1
As you can see two of the lines are commented out. However, both commented out commands are still running. I get emails stating that the RALUS agent restarted (another mystery since it's supposed to go to dev null according to the line above), and I can see that the memmon script is also running daily. Am I missing a step? Some other place I should be looking? Commenting out lines in your crontab is pretty much a no-brainer, so I appear to have less than no brain as this is a mystery to me.

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.

Is there a way that AWK can match lines from $1 and then print the last line into a file?
