Sep 09, 2016 Installing ‘tree’ for the Mac Command Line. If you want a little more control over ‘tree’ like the ability to specify a directory, or you just want the exact ‘tree’ equivalent that comes from the unix world, you can use homebrew or macports to install tree directly in macOS and Mac OS X. ## # A tibble: 21 x 11 ## pid ppid name username status user system rss vms created pshandle ## ## 1 6 zsh gaborcsa running 0.00595 0.00875 8.19e3 2.52e9 2018-07-23 21:06:28 psh ## 2 5 zsh gaborcsa running 0.243 0.111 1.64e4 2.52e9 2018-07-23 21:06:28 psh ## 3 7 zsh. How can I get a tree view like the one below on OSX? Vartec@someserver:$ ps xf PID TTY STAT TIME COMMAND 11519? S 0:00 sshd: vartec@pts/0 11520 pts/0 Ss 0:00 -bash 11528 pts/0 R+ 0:00 ps xf To clarify, I'm mostly interested in the tree structure, not the extended information.
This is supported in pstree(1) by using an option to show the tree only for a particular PID and providing the current process's PID ($$ in Bash), The option is named differently between GPL-licensed version by Werner Almesberger distributed with Debian and the BSD version by Fred Hucht distributed with MacOS. Sep 23, 2004 pstree is a small, command line (i.e., all-text mode) program that displays the processes (i.e., executing instances of programs) on the system in the form of a tree diagram. It differs from the much more commonly used (and more complex) ps program in a number of respects, including that the latter shows the processes in a list rather than a. So far I don't believe OSX has a built in that does this. But here's an answer I posted on stackexchange as well; a small perl script that determines the process hierarchy and prints it in an indented form using the output of OSX's built-in ps(1). Tested on OSX 10.6 and 10.9. May 19, 2014 Was happening all the time on macOS 10.12.5, SourceTree 2.5.2. Had to go to Keychain Access, remove all (SourceTree) entries (if you search for SourceTree, you'll find ' Access Key for '). Thay dated a few months back. After that, open SourceTree Preferences Accounts Edit (for each account), and enter the passwords again.
On Unix-like operating systems, the pstree command displays processes in tree format.
This document describes the GNU/Linux version of pstree.
Description
The pstree command shows running processes as a tree. The tree is rooted at either pid or init if pid is omitted. If a username is specified, all process trees rooted at processes owned by that user are shown.
Identical branches are merged by putting them in square brackets and prefixing them with the repetition count, for example:
becomes
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.,
If pstree is called as pstree.x11 then it will prompt the user at the end of the line to press return and will not return until that has happened. Doing this command is useful for when pstree is run in an xterminal.
Certain kernel or mount parameters, such as the hidepid option for procfs, will hide information for some processes. In these situations pstree will attempt to build the tree without this information, showing process names as question marks.
Syntax
Options
| -a | Show command linearguments. If the command line of a process is swapped out, that process is shown in parentheses. -a implicitly disables compaction for processes but not threads. |
| -A | Use ASCIIcharacters to draw the tree. |
| -c | Disable compaction of identical subtrees. By default, subtrees are compacted whenever possible. |
| -G | Use VT100 line drawing characters. |
| -h | Highlight the current process and its ancestors. This switch is a no-op if the terminal doesn't support highlighting or if neither the current process nor any of its ancestors are in the subtree being shown. |
| -H | Like -h, but highlight the specified process instead. Unlike with -h, pstree fails when using -H if highlighting is not available. |
| -g | Show PGIDs. Process Group IDs are shown as decimal numbers in parentheses after each process name. -p implicitly disables compaction. If both PIDs and PGIDs are displayed then PIDs are shown first. |
| -l | Display long lines. By default, lines are truncated to the display width or 132 if output is sent to a non-tty or if the display width is unknown. |
| -n | Sort processes with the same ancestor by PID instead of by name. (Numeric sort.) |
| -p | Show PIDs. PIDs are shown as decimal numbers in parentheses after each process name. -p implicitly disables compaction. |
| -s | Show parent processes of the specified process. |
| -u | Show uid transitions. Whenever the uid of a process differs from the uid of its parent, the new uid is shown in parentheses after the process name. |
| -U | Use UTF-8 (Unicode) line drawing characters. Under Linux 1.1-54 and above, UTF-8 mode is entered on the console with echo -e ' 33%8' and left with echo -e ' 33%@' |
| -V | Display version information. |
| -Z | (SELinux) Show security context for each process. This flag will only work if pstree is compilied with SELinux support. |
Examples
Display all processes as a tree, with the current process and its ancestors highlighted. Output will resemble the following:
Related commands
ps — Report the status of a process or processes.
top — Display a sortable, continually-updated list of processes.
Name
pstree - display a tree of processes

Options
-aShow command line arguments. If the command line of a process is swapped out, that process is shown in parentheses. -a implicitly disablescompaction.
-A
Use ASCII characters to draw the tree.
-c
Disable compaction of identical subtrees. By default, subtrees are compacted whenever possible.
-G
Use VT100 line drawing characters.
-h
Highlight the current process and its ancestors. This is a no-op if the terminal doesn't support highlighting or if neither the current process nor any ofits ancestors are in the subtree being shown.
