NAME

jexec — execute a command inside an existing jail

SYNOPSIS

jexec

[ -u username | -U username] jail command ...

DESCRIPTION

The jexec utility executes command inside the jail identified by its jid or name.

The following options are available:

-u username

The user name from host environment as whom the command should run.

-U username

The user name from jailed environment as whom the command should run.

SEE ALSO

jail_attach(2), jail(8), jls(8)

HISTORY

The jexec utility was added in FreeBSD 5.1.

BUGS

If the jail is not identified by jid there is a possible race in between the lookup of the jail and executing the command inside the jail. Giving a jid has a similar race as another process can stop the jail and start another one after the user looked up the jid.
