Linux command-line aliases are great for helping you work more efficiently. Better still, some are included by default in your installed Linux distro.

This is an example of a command-line alias in Fedora 27:

The command `alias` shows the list of existing aliases. Setting an alias is as simple as typing:

`alias new_name="command"`

Here are 15 command-line aliases that will save you time:

1. To install any utility/application:

`alias install="sudo yum install -y"`

Here, `sudo` and `-y` are optional as per user’s preferences:

3. To upgrade the system:

`alias upgrade="sudo yum upgrade -y"`
