Class Method Details

.getegid ⇒ Fixnum (mod_func)

Alias for GID.eid. Returns the effective group ID for this process. Not available on all platforms.

Process.egid   #=> 500

.issetugid ⇒ Boolean (mod_func)

Returns true if the process was created as a result of an execve(2) system call which had either of the setuid or setgid bits set (and extra privileges were given as a result) or if it has changed any of its real, effective or saved user or group IDs since it began execution.

.setegid(group) ⇒ nil (mod_func)

Set the effective group ID of the calling process to group. Not available on all platforms.

.seteuid(user) ⇒ nil (mod_func)

Set the effective user ID of the calling process to user. Not available on all platforms.

.setgid(group) ⇒ nil (mod_func)

Set the group ID of the current process to group. Not available on all platforms.

.setregid(rid, eid) ⇒ nil (mod_func)

Sets the (group) real and/or effective group IDs of the current process to rid and eid, respectively. A value of -1 for either means to leave that ID unchanged. Not available on all platforms.

.setresgid(rid, eid, sid) ⇒ nil (mod_func)

Sets the (group) real, effective, and saved user IDs of the current process to rid, eid, and sid respectively. A value of -1 for any value means to leave that ID unchanged. Not available on all platforms.

.setresuid(rid, eid, sid) ⇒ nil (mod_func)

Sets the (user) real, effective, and saved user IDs of the current process to rid, eid, and sid respectively. A value of -1 for any value means to leave that ID unchanged. Not available on all platforms.

.setreuid(rid, eid) ⇒ nil (mod_func)

Sets the (user) real and/or effective user IDs of the current process to rid and eid, respectively. A value of -1 for either means to leave that ID unchanged. Not available on all platforms.

.setrgid(group) ⇒ nil (mod_func)

Set the real group ID of the calling process to group. Not available on all platforms.

.setruid(user) ⇒ nil (mod_func)

Set the real user ID of the calling process to user. Not available on all platforms.

.setuid(user) ⇒ nil (mod_func)

Set the user ID of the current process to user. Not available on all platforms.
