function::ns_egid - Linux
Overview
The function::ns_egid
command provides a namespace-aware wrapper around the getegid
system call, retrieving the effective group ID of the current process within the specified namespace.
Syntax
function::ns_egid [--ns=<namespace>]
Options/Flags
--ns=<namespace>
: Specify the namespace for which the effective group ID will be retrieved. Defaults to the current namespace.
Examples
- Get the effective group ID in the current namespace:
function::ns_egid
- Get the effective group ID in a specific namespace:
function::ns_egid --ns=my-namespace
Common Issues
- Error: Invalid namespace: Ensure that the specified namespace exists and is valid.
Integration
The function::ns_egid
command can be used in conjunction with other tools to manage and inspect process attributes in different namespaces. For example, it can be used with the nsenter
command to enter a specific namespace and retrieve the effective group ID of the current process within that namespace.
