General :: Correct Usage Of Grep To Search A Disk?
Mar 26, 2009
I've been trying to identify all files on my cut-down version of Damn Small which contain the text string "User Agent:" in them. Because it's only 120Mb in its entirety, I'm quite happy to have grep search the whole system. I'm using this command, but it just generates errors as you can see:
[root@localhost ~]# grep -R 'User Agent:' /*
grep: /dev/dri/card0: Invalid argument
grep: /dev/fuse: Operation not permitted

I have done a bunch of searches on this but the terms seem to get tangled in the more popular search of "colouring the output of grep / awk". I am trying to find a way to grep/awk through the output of a command to find text of a specific colour. The command's output has a range of colours signifying too many different things to specify using text, with colour being the only form of grouping.

I need to search for the following pattern with GREP in a text file:
So I tried already:
But none of those works...I think probably because GREP doens't like the special character > in the middle of the serach pattern.
At the end I just need to now if GREP found the pattern in the file or not, so it should give me a 0 or a 1 back, once I check the value of the variable "?" after using the grep command.

I need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:
number="1234567890"
number="22390"
I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.

I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:
[root@Zion ~]# df -h

How can i use grep (or any other command) to check for lines that begin with N number.
E.g. I want to print out commands (from history), but only from the command number 50 until #200.
This one doesn't work:
Code:
history | grep "^[50-200]"
Should print out something like:
Code:
50 cd ~/Desktop

I have a mail.log file, of which I want to redirect only the search strings of the sender from=<example.sender@exampledomain.com> and the size size=4537 to a file.
In every case the sender string starts as from=<> and the size string starts as size=
What would be the grep command to redirect only the two search strings to a .txt file?

somewhere lurking is a file containing the default print resolution, which is not being overwritten by printer settings or cups management. I've asked on the cup forum and nothing successful.
So here's the question:
How can I configure grep to search recursively through all files in a directory, or if need be starting from root to find the pattern "2880" I've looked in the man page for grep and I can't see how to do it, is grep the right tool to use for this ?

I want to pipe the output of a command into grep as the search TERM, rather than the text to be searched, like this for example
Code:
cat /var/log/auth.log | grep date "&b &d"
so that I only see the lines in auth.log for the current day...but obviously that line doesn't work.... is there a way to do this with grep, or even another command?

I know grep can search recursively (ie through all subdirectories to the bottom of the directory tree), but is it possible to ask grep to only search say, 3 levels down? That means the current directory, any directories in the current directory, and within any directories within those?

I am trying to get my head around my new server. I am using CENTOS 5.4 x86_64 with 300GB harddrive.
The 300 GB been partitioned with the following:
Device Size Used Available Percent Used Mount Point
/dev/md0 99M 18M 77M 19% /boot
/dev/md1 16G 8.7G 5.8G 61% /
/dev/md2 246G 40G 194G 18% /home
/dev/md3 4.8G 1.6G 3.0G 35% /var
/usr/tmpDSK 3.9G 432M 3.3G 12% /tmp
I have increased teh tmpDSK as it was getting full very quickly. My question is, what are these md0; md1, md2 and md3 are they harddrive partitions and as md1 is getting full will that have an impact on my sites.

Trying to understand grep,sed,awk but maybe its too early for me and also i suspect iostat is not the correct program for exactly what i'm looking for...The goal is to print only the current read and write speeds of the disk, represented in a numerical value with two separated commands. So for example when writing a file to disk from an external disk, the value reflects the speed of the process.
"iostat -dk sda" prints
