NAME

-d, --delay seconds: Update interrupt output every seconds intervals.
-s, --sort column: Specify sort criteria by column name. See --help output to get column names. The sort criteria may be changes in interactive mode.
-V, --version: Display version information and exit.
-h, --help: Display help text and exit.

INTERACTIVE MODE KEY COMMANDS

i: sort by short irq name or number field
t: sort by total count of interrupts (the default)
d: sort by delta count of interrupts
n: sort by long descriptive name field
