Name

fs_usage

Synopsis

fs_usage [options] [processes]

Shows a continuous display of filesystem-related system calls and page faults. You must run fs_usage as root. By default, it ignores anything originating from fs_usage, Terminal, telnetd, sshd, rlogind, tcsh, csh, or sh, but shows all other system processes. To have fs_usage track only specific processes, specify those process names or IDs in processes.

Options

-e [processes]

Exclude from tracking those processes specified in processes. If no processes are given, exclude only the current fs_usage process.

-f mode

Filter output according to the mode, which must be network, filesys, or cachehit.

-w

Display in a more detailed, wider format. Lines longer than the window width will be wrapped.
