How to get the basic linux ps functionality in mac? In linux the basic ps command only shows very basic information about the processes running in the same terminal. 

For example:

[root@localhost ~]# sleep 100 &amp;
[1] 4071
[root@localhost ~]# ps
  PID TTY          TIME CMD
 4025 pts/2    00:00:00 bash
 4071 pts/2    00:00:00 sleep
 4078 pts/2    00:00:00 ps
[root@localhost ~]# 


What is the way to achieve the same simple output in mac? 

The ps without any options in mac, prints a lot more information than processes running in the same terminal.  



Apparently there is no ps port from linux to mac for a good reason 



About the ps that I have :
Running El Capitan 10.11.6

$ which -a ps
/bin/ps 



$ ps --version
ps: illegal option -- -
usage: ps [-AaCcEefhjlMmrSTvwXx] [-O fmt | -o fmt] [-G gid[,gid...]]
          [-g grp[,grp...]] [-u [uid,uid...]]
          [-p pid[,pid...]] [-t tty[,tty...]] [-U user[,user...]]
       ps [-L]


Some example output

$ /bin/ps | wc -l
          69

$ ps | grep iTerm

I gather the concern is that the MacOS version of ps follows BSD conventions and displays all your processes associated with any controlling terminal. Linux ps follows System V/POSIX conventions and shows your processes on the current controlling terminal.

To replicate the POSIX behavior, just run ps -T.
