GETCONF(1) FreeBSD General Commands Manual GETCONF(1)
NAME
getconf - get configuration values
SYNOPSIS
getconf system_var
getconf path_var pathname
getconf -a [pathname]
DESCRIPTION
The getconf utility writes the current value of a configurable system
limit or option variable to the standard output.
The system_var argument specifies the system variable to be queried. The
names of the system variables are from sysconf(3) with the leading "_SC_"
removed.
The path_var argument specifies the pathname variable to be queried for
the specified pathname argument. The names of the pathname variables are
from pathconf(2) with the leading "_PC_" removed.
When invoked with the option -a, getconf writes a list of all applicable
variables and their values to the standard output, in the format "name =
value".
For compatibility with other operating systems, getconf will ignore
leading underscores in the names specified in the system_var and path_var
arguments.
EXIT STATUS
The getconf utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
To retrieve the number of configured processors, use:
$ getconf NPROCESSORS_CONF
To retrieve the maximum number of bytes (excluding the trailing NUL) for
a filename in the current directory, use:
$ getconf NAME_MAX .
