Displaying line numbers in vi/vim can be very useful for debugging code errors and to improve overall readability of a program. For example, if we are writing C program or Shell script and want to check coding mistakes after running or compiling it, turning on or off this feature may help a lot to identify coding problem.

Display line numbers in vi/vim

To display line numbers along the left side of a window, type any one of the following:

:set nu

or

:set number

Sample output

Hide line numbers in vi/vim

To turn off line number again, type the following command:

:set nu!

Make vi/vim show line numbers by default

The vimrc files contains optional runtime configuration settings to initialize vi/vim when it starts. On Unix/Linux based systems, the file is named .vimrc. To display line numbers every time you start vi/vim, append following line to your ~/.vimrc file:

set number

Save and close the file, type

:wq!

If you have very large mysql database then it is very hard to backup and restore using the conventional phpmyadmin or any other programs.
In this Tutorial I will explain you how to backup and restore a larger database. This tutorial can be used while moving your database from one server to another.
First you need to have shell (ssh) access to your server. Then follow the steps:

To Backup Mysql Database

root@lifelinux:~# mysqldump  -u [username] -p[password] [dbname] > [backup.sql]

[username] is your database user name
[password] is the password for your database (Note: there is no space between -p and the password)
[dbname] is The name of your database
[backup.sql] is The file name for your database backup

Backup Mysql Database with compress

If your mysql database is very big, you might want to compress the output of mysql dump. Just use the mysql backup command below and pipe the output to gzip, then you will get the output as gzip file.

root@lifelinux:~# mysqldump -u [username] -p[password] [dbname] | gzip -9 > [backup.sql.gz]

Restore Mysql Database

To restore the database you need to create the database in target machine then use this command

root@lifelinux:~# mysql -u [username] -p[password] [dbname] < [backup.sql]

Restore Compressed Mysql Database

root@lifelinux:~# gunzip < [backup.sql.gz] | mysql -u [username] -p[password] [dbname]
