Changing The Frequency Of StartUp Disk Checks On Linux

Opened hard drive with top magnet removed, sho...

Linux systems commonly run on ext2/ext3/ext4 file systems. These file-systems have a built-in feature to tell the operating system to do a disk check while booting up if the number of times the disk has been mounted exceeds a certain number. Most commonly the count is set to 30.

This is an inconvenience to anyone who regularly switches off the system, its even worse if the hard disk sizes reach 1Tb. So changing the number to suit your preference might be an excellent idea.


Changing the maximum mount count:

sudo tune2fs -c 50 /dev/sda1

Here:
tune2fs is the command that allows modification on the disk flags
-c enables the max mount count to be changed to the next parameter(50 in this case)
/dev/sda1 is the partition on which to do the operation

Changing the maximum time count:

sudo tune2fs -i 30d /dev/sda1

Here:
tune2fs is the command that allows modification on the disk flags
-i enables the max time count to be changed to the next parameter(30d in this case means the consecutive checks are scheduled 30 days apart). This parameter can be also give in terms of months(2m for 2 months) and weeks(3w for 3 weeks)
/dev/sda1 is the partition on which to do the operation

Search for Multiple Strings in Linux Command Line

Problem:  I have a text file with a lot of information, I need to pick lines of information containing a particular pattern(s) and store it in another file

Solution: Use egrep to filter out lines with required pattens and write the result in a file.

egrep is actually a short form for “grep -E”, a command used to handle pattens while searching.

For Eg.
Lets say you have a text file with a list of file names and you want to filter out only those names that are of a certian type. For the sake of this example lets assume you want to only see filenames of files ending with .mp3 or .wav or .ogg

The command you need to use is:

cat file | egrep “.mp3|.wav|.ogg” > musiclist.txt

Voila you now have a file that sorts out your music files.

Bonus: If you want to list out all the music files you have stored under a particular directory you can use the following command

ls -1R /path/to/music | egrep “.mp3|.wav|.ogg” > musiclist.txt
