I just found a cool trick thanks to a colleague of mine David Saliba, to cleverly use the Linux
ps tool to display a list of processes in a hierarchical order by using the
fax flags (and it's easy to remember!):
[root@db10 ~]# ps fax | less
12778 ? S 0:00 vncconfig -iconic
12779 ? S 2:19 xterm -geometry 80x24+10+10 -ls db10:1
12782 pts/2 Ss+ 0:00 \_ -bash
15101 pts/2 S 14:10 \_ xterm
15103 pts/3 Ss 0:00 | \_ bash
15121 pts/3 S+ 153:10 | \_ top
15123 pts/2 S 2:01 \_ xterm
15125 pts/4 Ss 0:00 \_ bash
15143 pts/4 S+ 1:12 \_ tail -f alert_dbp10.log
12780 ? S 0:00 twm
32399 ? S 1:31 xterm
32401 pts/5 Ss+ 0:00 \_ bash
Also, if you pipe the command to
less you can actually scroll sideways to see the whole command string if it does not fit completely in the screen.
[root@tst-str-dbp10 ~]# ps fax | less
