function::task_egid - Linux

Overview

task_egid retrieves the effective group ID of a task. The effective group ID is the group ID that the task will use if it performs operations that are controlled by file system permissions, such as creating files.

Syntax

task_egid [<pid>]

If no PID is specified, the effective group ID of the current task is retrieved.

Options/Flags

None.

Examples

To retrieve the effective group ID of the current task:

$ task_egid
100

To retrieve the effective group ID of a specific task:

$ task_egid 1234
100

Common Issues

If the specified task does not exist, task_egid will return an error.

Integration

task_egid can be used in conjunction with other commands to perform advanced tasks. For example, it can be used with the ps command to identify tasks that are running with a specific effective group ID.

$ ps -e | task_egid
PID  User     Group      EGID Command
