/usr/bin/getconf -a
/usr/xpg4/bin/getconf [-v specification] system_var
/usr/xpg4/bin/getconf [-v specification] path_var pathname
/usr/xpg4/bin/getconf -a
/usr/xpg6/bin/getconf [-v specification] system_var
/usr/xpg6/bin/getconf [-v specification] path_var pathname
/usr/xpg6/bin/getconf -a
/usr/xpg7/bin/getconf [-v specification] system_var
/usr/xpg7/bin/getconf [-v specification] path_var pathname
/usr/xpg7/bin/getconf -a
DESCRIPTION
In the first synopsis form, the getconf utility writes to the standard
output the value of the variable specified by system_var, in accordance
with specification if the -v option is used.
In the second synopsis form, getconf writes to the standard output the
value of the variable specified by path_var for the path specified by
pathname, in accordance with specification if the -v option is used.
In the third synopsis form, config writes to the standard output the
names of the current system configuration variables.
The value of each configuration variable is determined as if it were
obtained by calling the function from which it is defined to be avail‐
able. The value reflects conditions in the current operating environ‐
ment.
OPTIONS
The following options are supported:
-a
Writes all names and its values of the current system configuration
variables to the standard output.
-v specification
Gives the specification which governs the selection of values for
configuration variables.
OPERANDS
The following operands are supported:
path_var
A name of a configuration variable whose value is available from
the pathconf(2) function.
pathname
A path name for which the variable specified by path_var is to be
determined.
system_var
A name of a configuration variable whose value is available from
system interface confstr(3C), sysconf(3C) or are defined in system
header files limits.h(3HEAD) or unistd.h(3HEAD).
The symbol PATH also is recognized, yielding the same value as the con‐
fstr() name value CS_PATH.
EXAMPLES
Example 1 Writing the Value of a Variable
This example illustrates the value of {NGROUPS_MAX}:
example% getconf NGROUPS_MAX
Example 2 Writing the Value of a Variable for a Specific Directory
This example illustrates the value of NAME_MAX for a specific direc‐
tory:
example% getconf NAME_MAX /usr
Example 3 Dealing with Unspecified Results
This example shows how to deal more carefully with results that might
be unspecified:
if value=$(getconf PATH_MAX /usr); then
if [ "$value" = "undefined" ]; then
echo PATH_MAX in /usr is infinite.
else
echo PATH_MAX in /usr is $value.
fi
else
echo Error in getconf.
fi
For example:
sysconf(_SC_POSIX_C_BIND);
and
system("getconf POSIX2_C_BIND");
in a C program could give different answers. The sysconf call supplies
a value that corresponds to the conditions when the program was either
compiled or executed, depending on the implementation. The system call
to getconf always supplies a value corresponding to conditions when the
program is executed.
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of getconf: LANG, LC_ALL, LC_CTYPE, LC_MES‐
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 The specified variable is valid and information about its current
state was written successfully.
>0 An error occurred.
