System Information
- Display if system 64 or 32 bit: isainfo options
- -v Prints detailed information about the other options
- -b Prints the number of bits in the address space of the native instruction set.
- -n Prints the name of the native instruction set used by portable applications supported by the current version of the OS.
- -k Prints the name of the instruction set or sets that are used by the OS kernel components such as device drivers and STREAMS modules.
- Show release info: cat /etc/release
- Show Physical Processor Type:
- psrinfo -p <- to display total number of physical processors
- prsinfo -v <- to display info on each virtual processor
- Show how many system events have taken place since last reboot vmstat -s
Information About Processes
preap [-F] <pid> <- Force a defunct process to be reaped by its parent pargs <pid> <- Print arguements associated with a process pargs -l <pid> <- Print arguements in single line pargs -e <pid> <- Print environment variables associated with a process # pgrep cron (Obtains the process ID for the cron process) 4780 # pwdx 4780 (Displays the current working directory for the cron process) 4780: /var/spool/cron/atjobs # ptree 4780 (Displays the process tree that contains the cron process) 4780 /usr/sbin/cron
and all the related [from proc(1) man page] :
pflags Print the /proc tracing flags, the pend- ing and held signals, and other /proc status information for each lwp in each process. pcred Print or set the credentials (effective, real, saved UIDs and GIDs) of each pro- cess. pldd List the dynamic libraries linked into each process, including shared objects explicitly attached using dlopen(3C). See also ldd(1). psig List the signal actions and handlers of each process. See signal.h(3HEAD). pstack Print a hex+symbolic stack trace for each lwp in each process. pfiles Report fstat(2) and fcntl(2) information for all open files in each process. In addition, a path to the file is reported if the information is available from /proc/pid/path. This is not necessarily the same name used to open the file. See proc(4) for more information. pwdx Print the current working directory of each process. pstop Stop each process (PR_REQUESTED stop). prun Set each process running (inverse of pstop). pwait Wait for all of the specified processes to terminate. ptime Time the command, like time(1), but using microstate accounting for reprodu- cible precision. Unlike time(1), chil- dren of the command are not timed.
