Linux Command: alias

Alias
Alias the command.
Eg:
Alias LL = 'LS-al'

The use of alias on the terminal is only available this time. The definition of Alias is usually placed in. bashrc under the user's home directory, using vi ~ /. Bashrc check whether there are several default defined alias? For example:
# Some More ls aliases
Alias LL = 'LS-al'
# Alias LA = 'LS-'

If you need to restart the service every time, add a line in it and save the alias you want to define and restart it.
Also, if you want to add the alias LL = 'LS-al' line to the end of/etc/bashrc, bashrc is the environment variable configuration file/etc/bashrc and ~ /. The difference between bashrc and bashrc is that it is set for all systems and for single users.
