Linux Command alias is a powerful tool that allows users to create shortcuts for commonly used commands. It is a great way to save time and effort when typing commands in the terminal. With alias, users can create custom commands that can be used to quickly execute a series of commands or to quickly access a specific directory. Alias can also be used to create shortcuts for long and complex commands. This tutorial will provide an overview of how to use alias and how to create custom commands.
Alias is a Linux command that allows users to create shortcuts for longer commands.
alias ls=’ls -l’
This command creates an alias for the ls command, so that when the user types ls, the command ls -l is executed instead.
Linux Command Alias
An alias is a command that can be used to substitute a string of characters for another string of characters. Aliases are commonly used to make frequently used commands shorter and easier to type. Aliases can also be used to make a command more descriptive, making it easier to remember.
In Linux, aliases are created using the alias command. The syntax for creating an alias is as follows:
For example, if you wanted to create an alias for the ls command, you could use the following command:
alias ll="ls -l"
This would create an alias called ll that would run the ls -l command when it is used. To use the alias, simply type ll instead of ls -l.
Aliases can also be used to create shortcuts for longer commands. For example, if you wanted to create an alias for the command to list all files in a directory, you could use the following command:
alias lf="ls -l | grep -v ^d"
This would create an alias called lf that would run the ls -l | grep -v ^d command when it is used. To use the alias, simply type lf instead of the full command.
Aliases can be very useful for making frequently used commands easier to type and remember. They can also be used to create shortcuts for longer commands. To view a list of all aliases that have been created, use the alias command without any arguments.
