A collection of tips & tricks for using Linux...
Contents
Restart a service[edit | edit source]
sudo service FOOBAR restart
or
sudo systemctl restart FOOBAR.service
Where "FOOBAR" is the name of the service you want to restart...
Taking a screenshot in Mint Cinnamon[edit | edit source]
Here are the default shortcuts. You can customize them in Keyboard Settings, as shown in the image that started this post.
| Action | Shortcut |
|---|---|
| Take a screenshot | Print
|
| Take a screenshot of a window | Alt + Print
|
| Take a screenshot of an area | Shift + Print
|
| Copy screen to clipboard | Control + Print
|
| Copy window to clipboard | Control + Alt + Print
|
| Copy area to clipboard | Shift + Control + Print
|
| Toggle recording desktop | Shift + Control + Alt + R
|
Print may have its own special label on your keyboard. On mine the Print key is labeled PrtSc.
Testing Network Connectivity
A handy little script:
#!/bin/bash if nc -zw1 pfSense 443 then echo "We have DNS..." else echo "NOPE! No DNS..." sudo systemctl restart systemd-resolved exit fi
Uses netcat (nc) to simply check if the router (pfsense) is currently findable by name & responding to HTTPS (port 443).
Then either tells you if it's OK or asks for your password to restart the DNS resolver.
