Switch User Execute command method in Linux shell script __linux

Often when writing a shell script, you will encounter a different user to execute the relevant commands, the way to simply note:

1. Execute a single command: su-user-c "command"

For example, the following command is to create a test123 directory under the/data directory with the test user

[root@slave19/data]# su-test-c "mkdir/data/test123"

2. Execute batch order: Su-user-s/bin/bash shell_command_file.sh

Cases:

[root@slave19/data]# su-test-s/bin/sh/data/test.sh

[root@slave19/data]# Cat test.sh

#!/bin/sh

Mkdir/data/testggg

The script above is to create the TESTGGG directory under the/data directory with the test user
