How to use Pipeline to avoid entering password in sudo Command

This article is about how to use pipes to implement the sudo command without entering a password. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

As a result of learning php, linux also installed a xampp integration environment package. However, every time you start up, you have to enter the terminal, and then click/opt/lampp/in turn, and then sudo executes manager-linux-x64.run operation to open the graphical console of xampp, which is very inconvenient.

So I wrote a script with the intention of opening the console program with one click.

It started out like this:

The code is as follows:

#!/ bin/bash

#Execute xampp console

cd /opt/lampp/

sudo ./ manager-linux-x64.run

However, after execution, you will still be asked to enter the password, which is very inconvenient.

So thought of the pipeline, after modification, finally can not enter the password, a key sudo and open the program.

Format: echo 'your password'| sudo -S execute command

The code is as follows:

#!/ bin/bash

#Execute xampp console

cd /opt/lampp/

echo 'yourpassword'|sudo -S ./ manager-linux-x64.run
