groupadd / groupmod / groupdel — Group Account Management
Category
User & Group Management
License
BSD-3-Clause (shadow-utils)
Source
https://github.com/shadow-maint/shadow (included in all Linux distributions)
Purpose
Create, modify, and delete groups. Companion to useradd — together they provide full user and group lifecycle management.
Use Cases
- Create dedicated groups for Mitiga agent operations (e.g.,
mitiga_agents) - Remove unauthorized or orphaned groups
- Modify group properties (name, GID)
- Audit group membership as part of access control reviews
Examples
# Create a dedicated group for Mitiga agents
groupadd mitiga_agents
# Create a system group (low GID, no login)
groupadd --system mitiga_svc
# Rename a group
groupmod -n new_name old_name
# Delete an unauthorized group (after verifying no active members)
groupdel unauthorized_group
# List all groups (via getent)
getent group
# List members of a specific group
getent group mitiga_agents
Safety Notes
- All group operations require explicit system manager approval. These commands are never executed autonomously.
- Always verify current group state with
getent groupbefore modifications. - Deleting a group that owns files creates orphaned ownership — audit with
find / -gid <gid> -lsbefore deletion. - Record the previous state in logs before any changes.
- Modifying system groups (root, wheel, sudo, adm) is extremely high-risk and requires documented justification.
