# checkgid(8)

validate group identifiers

## NAME

**checkgid** – validate group identifiers

## SYNOPSIS

**checkgid** *group* *...*

## DESCRIPTION

Given one or more group identifers on the command line (e.g., "httpd" or "#-1"), figure out whether they'll be valid for the server to use at run-time.

If a groupname isn't found, or we can't setgid() to it, return -1.  If all groups are valid, return 0.

This may need to be run as the superuser for the setgid() to succeed; running it as any other user may result in a false negative.
