Hide Output of NMCLI Network Command in Terminal
In Linux, the nmcli command is used to manage network connections. When executing this command, the output is displayed directly in the terminal. However, sometimes you might want to hide this output, for example, when running scripts or automating tasks.
To hide the output of the nmcli command in the terminal, you can redirect the output to /dev/null. This is a special file that discards all data written to it. By redirecting the output to this file, you effectively hide it from the user.
Redirecting Output to /dev/null
To redirect the output of the nmcli command to /dev/null, you can use the following syntax:
sudo nano >/dev/null 2>&1Here, sudo is used to run the command with root privileges, nano is the command you want to execute, and >/dev/null 2>&1 redirects the output to /dev/null.
Example: Hiding IPv6 Address Configuration Output
For example, if you want to hide the output of the IPv6 address configuration process, you can use the following command:
sudo nmcli device status | grep ip6 >/dev/null 2>&1Here, nmcli device status is used to display the network device status, and given ip6 filters the output to show only the IPv6 addresses. The output is then redirected to /dev/null using >/dev/null 2>&1.
- The output of the
nmclicommand can be hidden in the terminal by redirecting it to/dev/nullusing the syntaxsudo nmcli >/dev/null 2>&1. - Redirecting the output to
/dev/nulldiscards all data written to it, effectively hiding it from the user. - This output redirection technique can be useful when running scripts or automating tasks where the output of the
nmclicommand is not needed.
