SETCAP(8) (2020-01-07) SETCAP(8) NAME setcap - set file capabilities SYNOPSIS setcap [-q] [-n <rootuid>] [-v] {capabilities|-|-r} filename [ ... capabilitiesN fileN ] DESCRIPTION In the absence of the -v (verify) option setcap sets the capabilities of each specified filename to the capabilities specified. The optional -n <rootuid> argument can be used to set the file capability for use only in a user namespace with this root user ID owner. The -v option is used to ver- ify that the specified capabilities are currently associated with the file. If -v and -n are supplied, the -n <rootuid> argument is also verified. The capabilities are specified in the form described in cap_from_text(3). The special capability string, '-', can be used to indicate that capabilities are read from the standard input. In such cases, the capability set is terminated with a blank line. The special capability string, '-r', is used to remove a capability set from a file. Note, setting an empty capabil- ity set is not the same as removing it. An empty set can be used to guarantee a file is not executed with privilege in spite of the fact that the prevailing ambient+inheritable sets would otherwise bestow capabilities on executed bina- ries. The -q flag is used to make the program less verbose in its output. EXIT CODE The setcap program will exit with a 0 exit code if success- ful. On failure, the exit code is 1.
