.Sh NAME
.Nm setcaps
.Nd set capability restrictions on calling process
.Sh SYNOPSIS
.Nm
.Op Fl lpqh
.Op cap[:es] ...
.Sh DESCRIPTION
The
.Nm
utility sets capability restrictions on the parent process, which is
typically the shell that ran this program.  By default the SELF and EXEC
flags are both set.
.Pp
When specifying capabilities to set, a colon extension may be used to
override the default restrictions.
.Pp
.Sh OPTIONS
The options are as follows:
.Bl -tag -width indent
.It Fl l
List current capabilities.
.It Fl p
Print a list of all available capabilities.
.It Fl q
Do not complain if a specified capability is not available.
.It Fl h
Print help and exit.
.El
.Sh FLAGS
.Bl -tag -width indent
.It Li :s
Sets the SELF flag. The capability restriction is applied to the
calling process.  However, SELF restrictions are not transfered
upon exec unless the EXEC flag is also specified.
.It Li :e
Sets the EXEC flag.  The capability restriction is applied to any
programs exec'd by the calling process.  EXEC becomes SELF when a
program is exec'd.  The EXEC flag remains set.
Note that fork alone does not activate EXEC flagged restrictions.
.It Li :se
Both flags may be specified (this is the default) for each capability
listed without specified flags).
.El
.Sh EXIT STATUS
.Nm
will exit 1 on error, and 0 on success.
.Sh EXAMPLES
.Li setcaps restricted_root
