General :: Find Pattern After Specific Pattern
Oct 11, 2010I want to go through a log file and find pattern1 and then a pattern2 only after pattern 1.So for example I want to know howManyRecords was in 13:30.I figured I grep for "start time for the job" and then only after that (and before the next occurence of that) grep for "howManyRecords". Is this a sane way?
View 1 Replies View RelatedGeneral :: Find Pattern And Comment Out 2 Lines After It?
Oct 14, 2010How 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.
General :: Add (not Replacing) A Pattern Match With A Similar Pattern?
Aug 30, 2009I'm writing a bash script to search html files, and when I find any occurrence of an img src tag like this:
<img src="123-picture-normal.jpg" alt="some random user entered text" border="0">
I want to add a second line below it that looks like:
<img src="123-picture-thumbnail.jpg" alt="some random user entered text" border="0">
All I need to do is duplicate the line but replace "normal" with "thumbnail"
Each file can have multiple img src tags with different numbered jpgs.
I have a feeling this is a job for sed, but I'm struggling with it. Any ideas?

Programming :: Find Pattern That Extends Over Several Lines?

Programming :: Use Sed To Find String Pattern And Delete Subsequent Characters?
May 3, 2010I have a file with a number of strings like the ones below

string2#mfaaeb2vr1rhserh
anotherstring#ji89ensrsegr
anotherone#m1ynmdt324nsdt
I'm trying to delete everything after #** so that
string1#maasdfeaveasdfawefas
string2#mfaaebvrserhserh
becomes
string1#ma
string2#mf
tried sed 's/#..*//g' but as you all will know it returns string1, string2 etc.

View 1 Replies View RelatedGeneral :: New Install Dumps To Grub CLI?
Nov 11, 2010I am trying to make a clean install of linux on three new 500G HDs. Because the last failure caused loss of my wife's pictures, I'm in the dog house. I know, I know. Back-up, back-up, back-up.I'm trying to set up a Raid 5 as partial insurance against disk failure (along with a frequent back up schedule). A friend suggested that I put 4-5 partitions in the raid array to aid in recovery if a disk fails (/boot, /, /var, /home, and swap). I know that swap doesn't get 'raided'. I've looked at 50+ tutorials on how to set up raid5 from a clean install and after installing the whole system. Nothing has helped or even addressed this issue so far.
Problem is that I have now tried installing 4 different flavors of linux (Ubuntu, Mint, and a couple of distros of Fedora) with the custom disk partitioning as mentioned above. I've tried installing grub on the MBR and the first partition (/boot). I've ensured that it pointed to the correct partition to find the kernel (/). I've tried everything that I can think of, and at every reboot, I get dumped to the grub CLI after bios post, regardless of distro. I cannot get the system to load the kernel.

Apr 29, 2010I have to enhance the behaviour of a backup script written in perl. I don't need to change it, what I need to do is to create a bash script that does some checks like file name and file size, execute the backup script then check if the backup files match the original files.Here's how I try to do it:
- read the files from the original files folder
- store them in an array
- search in the array the files that have a specific file extension
- store the file names that match the search pattern (I know the backup script skips some files so I can hardcode the search pattern)
- run the backup script
- read the files from the backup folder
- store them in an array
- compare the original files name and size stored in an array with those from the backup folder
- send a report email
General :: Kernel Dumps To The Wrong /var/crash?
May 2, 2011I'm running Scientific Linux 5.5 (equivalent to CentOS 5.5), and over the past two weeks, I have had a problem with my root partition filling up, preventing anyone from logging into the server.After searching for large files, and finding none, I was mystified when du told me that the root partition had only 660 MB of disk space used, whilst df showed it full. The problem was this: the /var/crash directory had been filled up by an 8GB crash file. Now, I'm a 'proper' sysadmin and make sure that /var has its own mount point, so the crash should not have touched the root partition at all. Except it did - instead of writing to /var/crash on /dev/mapper/VolGroup00-LogVol04 which is mounted as /var, it wrote the file to /dev/md0 directly, so when all the file systems were mounted, those files were hidden under the mounted /var.

I am looking to practice sample questions with some kind of simulation environment where the scenario is similar to the real-time scenario that we can expect in the exam. For instance, the system is already broken with what is mentioned in the question so that I can focus only on solving the problem rather than breaking it first.
