Resource monitor that shows usage and stats for processor, memory, disks, network and processes.


  • Easy to use, with a game inspired menu system.
  • Fast and "mostly" responsive UI with UP, DOWN keys process selection.
  • Function for showing detailed stats for selected process.
  • Ability to filter processes.
  • Easy switching between sorting options.
  • Send SIGTERM, SIGKILL, SIGINT to selected process.
  • UI menu for changing all config file options.
  • Auto scaling graph for network usage.
  • Shows message in menu if new version is available
  • Shows current read and write speeds for disks
  • Multiple data collection methods which can be switched if running on Linux


Bashtop now has theme support and a function to download missing local themes from repository.

See themes folder for available themes.

The builtin theme downloader places the default themes in $HOME/.config/bashtop/themes. User created themes should be placed in $HOME/.config/bashtop/user_themes to be safe from overwrites.

Let me know if you want to contribute with new themes.

Support and funding

Bug fixes and updates might be slow during normal workdays since I work full time as an industrial worker and don't have much time or energy left during the week. I'm looking into ways of funding this project that would allow me to take off time from my day job to work on this.

Any advice on how to get funding for open source projects is very welcome!


You can now sponsor this project through github, see my sponsors page for options.

Also added donation links for paypal and ko-fi.

Any support is greatly appreciated!


Mac Os X

Will not display correctly in the standard terminal! Recommended alternative iTerm2

Will also need to be run as superuser to display stats for processes not owned by user.

Linux, Mac Os X and FreeBSD

For correct display, a terminal with support for:

Also needs a UTF8 locale and a font that covers:

  • Unicode Block “Braille Patterns” U+2800 - U+28FF
  • Unicode Block “Geometric Shapes” U+25A0 - U+25FF
  • Unicode Block "Box Drawing" and "Block Elements" U+2500 - U+259F


Dropbear seems to not be able to set correct locale. So if accessing bashtop over ssh, OpenSSH is recommended.


Linux, OSX and FreeBSD

bash (v4.4 or later) Script functionality will most probably break with earlier versions. Bash version 5 is highly recommended to make use of $EPOCHREALTIME variable instead of a lot of external date command calls.

GNU coreutils

GNU sed

Linux using /proc for data collection

GNU grep

ps from procps-ng (v3.1.15 or later)

GNU awk

OSX and FreeBSD or Linux using psutil for data collection

Python3 (v3.6 or later)

psutil python module (v5.7.0 or later)

Optionals for additional stats

(Optional OSX) osx-cpu-temp Needed to show CPU temperatures.

(Optional Linux) lm-sensors Needed to show CPU temperatures.

(Optional Linux) iostat (part of sysstat) Needed if you want disk read/write stats and are not using psutil data collection.

(Optional OSX/Linux/FreeBSD) curl (v7.16.2 or later) Needed if you want messages about updates and the ability to download themes.

All options changeable from within UI. Config files stored in "$HOME/.config/bashtop" folder

bashtop.cfg: (auto generated if not found)

#? Config file for bashtop v. 0.9.21

#* Color theme, looks for a .theme file in "$HOME/.config/bashtop/themes" and "$HOME/.config/bashtop/user_themes"
#* Should be prefixed with either "themes/" or "user_themes/" depending on location, "Default" for builtin default theme

#* Update time in milliseconds, increases automatically if set below internal loops processing time, recommended 2000 ms or above for better sample times for graphs

#* Processes sorting, "pid" "program" "arguments" "threads" "user" "memory" "cpu lazy" "cpu responsive"
#* "cpu lazy" updates sorting over time, "cpu responsive" updates sorting directly
proc_sorting="cpu lazy"

#* Reverse sorting order, "true" or "false"

#* Show processes as a tree

#* Check cpu temperature, only works if "sensors", "vcgencmd" or "osx-cpu-temp" commands is available

#* Draw a clock at top of screen, formatting according to strftime, empty string to disable

#* Update main ui when menus are showing, set this to false if the menus is flickering too much for comfort

#* Custom cpu model name, empty string to disable

#* Enable error logging to "$HOME/.config/bashtop/error.log", "true" or "false"

#* Show color gradient in process list, "true" or "false"

#* If process cpu usage should be of the core it's running on or usage of the total available cpu power

#* Optional filter for shown disks, should be names of mountpoints, "root" replaces "/", separate multiple values with space

#* Enable check for new version from at start

#* Enable graphs with double the horizontal resolution, increases cpu usage

#* Enable the use of psutil python3 module for data collection, default on OSX
