In ps.c, the output length of the Context field is fixed to 32 characters. Consider increasing the width of this field? 736 len = printf("%5u %-32.32s %s ", 737 p->pid, 738 p->context ? p->context : "unknown", 739 p->state); If some process types are too long, the security attributes are truncated： PID CONTEXT STAT COMMAND 1370 system_u:system_r:os_busybox_t:s S /usr/sbin/rpc.mountd 1374 system_u:system_r:kernel_t:s0:c0 IW< [kworker/3:1H] 1411 system_u:system_r:os_busybox_t:s S {e3_daemon} /usr/local/UnifiedTest 1413 system_u:system_r:os_busybox_t:s S {e3_daemon} /usr/local/UnifiedTest 1419 system_u:system_r:os_busybox_t:s S sshd: /usr/sbin/sshd -D [listener] 1421 system_u:system_r:os_log_rsyslog S /usr/sbin/rsyslogd 1496 system_u:system_r:os_busybox_t:s S /bin/login -- 1497 system_u:system_r:os_busybox_t:s S -bash 1504 system_u:system_r:os_busybox_t:s R ps -Z 1505 system_u:system_r:os_busybox_t:s S tail -n 10 The complete information is as follows： PID CONTEXT STAT COMMAND 1370 system_u:system_r:os_busybox_t:s0:c0 S {rpc.mountd} /usr/ 1374 system_u:system_r:kernel_t:s0:c0 IW< [kworker/3:1H] 1411 system_u:system_r:os_busybox_t:s0:c0 S {e3_daemon} /usr/l 1413 system_u:system_r:os_busybox_t:s0:c0 S {e3_daemon} /usr/l 1419 system_u:system_r:os_busybox_t:s0:c0 S sshd: /usr/sbin/ss 1421 system_u:system_r:os_log_rsyslogd_t:s0:c0 S /usr/sbin/rsyslogd 1496 system_u:system_r:os_busybox_t:s0:c0 S /bin/login -- 1497 system_u:system_r:os_busybox_t:s0:c0 S -bash 1506 system_u:system_r:os_busybox_t:s0:c0 R ./ps -Z 1507 system_u:system_r:os_busybox_t:s0:c0 S tail -n 10
