Display a tree of processes.

    -a     show command line arguments
    -A     use ASCII line drawing characters
    -c     don't compact identical subtrees
    -h     highlight current process and its ancestors
    -H PID highlight this process and its ancestors
    -G     use VT100 line drawing characters
    -l     don't truncate long lines
    -n     sort output by PID
    -p     show PIDs; implies -c
    -u     show uid transitions
    -U     use UTF-8 (Unicode) line drawing characters
    -V     display version information
    -Z     show SELinux security contexts
    PID    start at this PID; default is 1 (init)
    USER   show only trees rooted at processes of this user
