getconf -- get configuration values
getconf system_var getconf path_var pathname getconf -a [pathname]
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 lead- ing underscores in the names specified in the system_var and path_var arguments.
The getconf utility exits 0 on success, and >0 if an error occurs.
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 .
