find context of the command process

Hi folks, It is hard to list a context of a process. For example: ps -ZC ls or ps -ZC tar only "ps -ZC sleep" returns context of the sleep process. # ps -ZC sleep LABEL PID TTY TIME CMD system_u:system_r:initrc_t:s0 11744 ? 00:00:00 sleep system_u:system_r:initrc_t:s0 13006 ? 00:00:00 sleep system_u:system_r:initrc_t:s0 14087 ? 00:00:00 sleep Any suggestions? --henry
