15 command-line aliases to save you time
|
||
======
|
||
|
||
|
||
|
||
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:

2. To update the system:
|
||
|
||
`alias update="sudo yum update -y"`
|
||
|
||
3. To upgrade the system:
|
||
|
||
`alias upgrade="sudo yum upgrade -y"`
|
||
|
||
4. To change to the root user:
|
||
|
||
`alias root="sudo su -"`
|
||
|
||
5. To change to "user," where "user" is set as your username:
|
||
|
||
`alias user="su user"`
|
||
|
||
6. To display the list of all available ports, their status, and IP:
|
||
|
||
`alias myip="ip -br -c a"`
|
||
|
||
7. To `ssh` to the server `myserver`:
|
||
|
||
`alias myserver="ssh user@my_server_ip”`
|
||
|
||
8. To list all processes in the system:
|
||
|
||
`alias process="ps -aux"`
|
||
|
||
9. To check the status of any system service:
|
||
|
||
`alias sstatus="sudo systemctl status"`
|
||
|
||
10. To restart any system service:
|
||
|
||
`alias srestart="sudo systemctl restart"`
|
||
|
