The command "setcap -r ${filename}" is used to remove capabilities from a file in Linux systems.
The "setcap" command allows you to set capabilities on an executable file or a script, which allows it to bypass certain security restrictions. These capabilities define specific privileges for the file, such as accessing certain devices or performing privileged operations without requiring root privileges.
In this specific command, "-r" is an option that stands for "remove" or "revoke". It is used to remove capabilities from a file specified by the variable ${filename}. The ${filename} should be replaced with the actual name of the file you want to remove capabilities from.
By running this command, the capabilities previously assigned to the specified file will be revoked, and the file will no longer have the additional privileges it had before.
