user subcommand

Edit online

The user subcommand (alias u) displays data from the kernel user structure.

Format

user [-ad] [-cr] [-f] [-w] [-s] [-ru] [-t] [-ut] [-64] [-32] [-s32] threadslot/eaddr

Parameters

Item Description
-ad Prints user adpsace information only.
-cr Prints credential information only.
-f Prints file information only.
-ru Prints profiling, resource, or limit information only.
-s Prints signal information only.
-t Prints timers information only.
-ut Prints user-thread information only.
-64 Prints 64-bit user information only.
-mc Prints miscellaneous user information only.
-w Prints Workload Manager (WLM) information only.
-32 Prints 32-bit STAB only.
-s32 Prints 32-bit signal information for a 64-bit process.

Examples

The user command displays the user structure as uthread and ublock, for a thread identified by its slot number or thread slot address. When the slot or address is not specified, it displays the user structure for the current thread. The options listed for the user command limit the output to some sections of the user structure.

Note: For all kdb subcommands, only a few output might be useful for AIX® users, because most of the output columns requires knowledge about of the corresponding subsystem's internals (in this case, process management).
