# revoke(1)

revoke a character device

## NAME

**revoke** – revoke a character device

## SYNOPSIS

**revoke** *file ...*

## DESCRIPTION

The **revoke** program revokes the character devices using [revoke(2)](/revoke/2.md). When used on a TTY, calls like [read(2)](/read/2.md), [write(2)](/write/2.md) and [ioctl(2)](/ioctl/2.md), will be aborted immediately, effectively causing login sessions to be terminated.

## SEE ALSO

[revoke(2)](/revoke/2.md)

## HISTORY

The **revoke** program first appeared in FreeBSD 8.0.
