NAME
getconf —
get configuration
values
SYNOPSIS
getconf |
path_var 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.
