getconf(1) OSS Shell and Utilities Reference Manual
NAME
getconf - Displays system configuration variable values
SYNOPSIS
getconf system_configuration
getconf path_configuration pathname
DESCRIPTION
The system_configuration argument specifies a system-wide configuration variable. The
path_configuration argument specifies a system path-configuration variable. The pathname
argument specifies a pathname for the path_configuration variable.
The system_configuration argument specifies system-configuration variables whose values are
valid throughout the system. There are two kinds of system-wide configuration values:
• System-wide configuration variables
• System standards configuration variables
The path_configuration argument specifies system path-configuration variables whose values
contain information about paths and the path structure in the system.
System-Wide Configuration Variables
System-wide configuration variables contain the minimum values met throughout all portions of
the system. The following list defines the system-wide configuration variables used with the
getconf command:
ARG_MAX
The maximum length, in bytes, of the arguments for one of the exec functions, includ-
ing environment data. atexit() per process.
BC_BASE_MAX
The maximum value allowed for the obase variable with the bc command.
BC_DIM_MAX
The maximum number of elements permitted in an array by the bc command.
BC_SCALE_MAX
The maximum value allowed for the scale variable with the bc command.
BC_STRING_MAX
The maximum length of string constants accepted by the bc command.
CHILD_MAX
The maximum number of simultaneous processes for each real user ID.
CLK_TCK
The number of clock ticks per second. The value of CLK_TCK may be variable, and
it should not be assumed that CLK_TCK is a compile-time constant.
COLL_WEIGHTS_MAX
The maximum number of weights that can be assigned to an entry in the
LC_COLLATE locale-dependent information in a locale-definition file.
CS_PATH
A value for the PATH environment variable that finds all standard utilities.
