This is pstree V 2.33. It is a small program that shows the ps
listing as a tree (as the name implies...). It has several options
to make selection criteria and to change the output style.
It should compile under most unixes, tested are AIX, Linux, HP-UX,
A/UX, SunOS, Solaris, (Free|Open|Net)BSD, MacOSX/Darwin, and others.
Under AIX & Linux, pstree directly reads the process table using
getproc()/getuser() or the /proc file system. Under all other
Un*xes pstree reads the output of /bin/ps.
If process group information is available, process group leaders
are marked with a '=' instead of '-'.
Take an ANSI C compiler, eg. gcc, and just enter
$ [g]cc -O -o pstree pstree.c
There is no Makefile. Have fun, Fred
See pstree.c
