Description

The getconf utility prints the value of the configuration variable specified by variable_name. If no pathname is given, getconf serves as a wrapper for the confstr and sysconf functions, supporting the symbolic constants defined in the limits.h and unistd.h headers, without their respective _CS_ or _SC_ prefixes.

If pathname is given, getconf prints the value of the configuration variable for the specified pathname. In this form, getconf serves as a wrapper for the pathconf function, supporting the symbolic constants defined in the unistd.h header, without the _PC_ prefix.

If you specify the -v option, the parameter denotes a specification for which the value of the configuration variable should be printed. Note that the only specifications supported by Cygwin are POSIX_V7_ILP32_OFFBIG and the legacy POSIX_V6_ILP32_OFFBIG and XBS5_ILP32_OFFBIG equivalents.

Use the -a option to print a list of all available configuration variables for the system, or given pathname, and their values.
