alias COMMAND:alias command allows you to create a shortcut to a command. As the name indicates, you can set alias/shortcut name for the commands/paths which is too longer to remember.
SYNTAX:The Syntax is
alias [options] [ AliasName [ =String ] ]
-a Removes all alias definitions from the current shell execution environment.
-p Prints the list of aliases in the form alias name=value on standard output.
EXAMPLE:To create a shortcut temporarily:
alias lhost=’cd /var/www/html’
This command will set lhost to cd /var/www/html/.
Now if you type lhost it will take you to the specified folder/directory.
To create a shortcut Permanently:
You can put your aliases into the /home/user/.bashrc file. It is good to add them at the end of the file.
alias home=’cd /var/www/html/hscripts/linux-commands’
Now if you type home it will take you to the specified folder/directory.
To create a shortcut for a command:
This command will set c to clear.
Now if you type c it will clear the screen.
