AutoUID and AutoGID

The ADD and REPLACE commands auto‑assignment of UID/GID numbers means that:

• Users can define a default range
• Users can restrict the search for an open number by entering a specific range
• If no number is assigned and no range is given, AutoUID/GID restricts the search by checking through the defined default range
• If no range is given and there is no default range, AutoUID/GID starts at 1 and searches until an available UID/GID is found
• Zeros are excluded in the range search

Examples: Auto‑assignment of UID and GID

TSS ADD|REP(acid|Group Acid) UID|GID(?) RANGE(<low>,<high>)
or
TSS ADD|REP(acid|Group Acid) UID|GID(?)
or
TSS ADD|REP(acid|Group Acid) UID|GID(?) RANGE(300,400)
