pstree

pstree output in FreeBSD

pstree is a Unix command that shows the running processes as a tree. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid.

Examples

pstree pid

user@host ~$ pstree 1066

         └─{rs:main Q:Reg}
