Installation Notes

Permission issue

On macOS, normal user can't access all process information of other users. On Linux, normal user can't access some information (ex. Read/Write throughput) of other users.

If you want to show all information, SUID bit must be set to procs binary. You can use --suid option to set it.

$ procs --suid
sudo sh -c "chown root [procs binary path]; chmod u+s [procs binary path]"
[sudo] password for ...:

procs --suid does chown and chmod with sudo.

--suid is not supported on Windows.

less setting

On some environments, less can't show UTF-8 charactors with default setting. In this case, the following environment variable may resolve it.

export LESSCHARSET=utf-8

The detail of the issue is #21.


Show all processes

Type procs only. It shows the information of all processes.

$ procs


Search by non-numeric keyword

If you add any keyword as argument, it is matched to USER, Command, Docker by default.

$ procs zsh


Search by numeric keyword

If a numeric is used as the keyword, it is matched to PID, TCP, UDP by default. Numeric is treated as exact match, and non-numeric is treated as partial match by default.

$ procs --or 6000 60000 60001 16723


Note that procfs permissions only allow identifying listening ports for processes owned by the current user, so not all ports will show up unless run as root.

Logical operation of search keywords

If there are some keywords, logical operation between the keywords can be specified by commandline option.

  • --and : The processes to match with all keywords are shown.
  • --or : The processes to match with any keyword are shown.
  • --nand: The processes are shown unless these match with all keywords.
  • --nor : The processes are shown unless these match with any keyword.

The default operation can be specified in the configuration file. See [search] section.

Show Docker container name

If you have access permission to docker daemon ( unix:///var/run/docker.sock ), Docker column is added.

$ procs growi


Note that procs gets the container information through UNIX domain socket, so Docker Toolbox on macOS ( doesn't use UNIX domain socket ) is not supported. Docker Desktop for Mac is supported but not tested.


If output lines exceed terminal height, pager is used automatically. This behavior and pager command can be specified by configuration file.

Watch mode

If --watch <second> option is used, procs automatically updates output like top. The update interval can be specified by the option argument.

Tree view

If --tree option is used, processes are sorted by dependency order and dependency tree is shown at left side.

$ procs --tree


Sort column

Column sort order can be changed by --sorta or --sortd option. The last charactor of --sorta and --sortd means sort order: "a"scending and "d"escending.

The column for sort is selected by the option keyword. The keyword is matched with column kind that is shonw by --list option. If --sorta cputime, column is sorted by CpuTime with ascending order. If --sortd rss, column is sorted by VmRss with decending order. The keyword is matched partially and case is ignored.

The default sort is specified by [sort] section in the configuration file.

$ procs --sortd cpu


Insert column

--insert option inserts new column to the position of Slot column. The column for insert is selected by the option keyword. The keyword is the same as sort option. A Slot column can be used by a inserted column. If many insertion is required, many Slot should be added. Unused Slot is not shown.


You can change configuration by writing a configuration file, like below.

The location of the configuration file is OS-specific:

  • Linux: ~/.config/procs/config.toml
  • macOS: ~/Library/Preferences/com.github.dalance.procs/config.toml
  • Windows: ~/AppData/Roaming/dalance/procs/config.toml

For compatibility, if ~/.procs.toml exists, it will be preferred to the OS-specific locations.

The complete example of a configuration file can be generated by --config option.
