The command "chcon" is used to change the SELinux security context of a file or a directory. SELinux (Security-Enhanced Linux) is a Linux kernel security module that provides additional access controls for files and processes.
The specific command "chcon -l ${range-level} ${filename}" has two parameters:
-
${range-level}: This represents the SELinux security context range level that you want to assign to the file. SELinux has security levels such as s0, s1, s2, etc., which define different levels of trustworthiness and access restrictions. The specific value for ${range-level} should be specified based on your system's SELinux policy.
-
${filename}: This represents the name of the file or directory for which you want to change the SELinux security context.
So, when you run the command "chcon -l ${range-level} ${filename}", it will change the SELinux security context of the specified ${filename} to the specified ${range-level}. This can be useful when you need to modify the access controls for a particular file or directory based on SELinux policies.
