Be aware the appropriate package is sometimes still called libncurses5 (on Debian/Ubuntu).

If building statically and `libsystemd` is not found by `configure`, support for the systemd meter is disabled entirely. - -`htop` checks for the availability of the actual runtime libraries as `htop` runs. - -#### BSD -On most BSD systems `kvm` is a requirement to read kernel information. - -More information on required and optional dependencies can be found in [configure.ac](configure.ac). - -## Usage -See the manual page (`man htop`) or the help menu (**F1** or **h** inside `htop`) for a list of supported key commands. - -## Support - -If you have trouble running `htop` please consult your operating system / Linux distribution documentation for getting support and filing bugs. - -## Bugs, development feedback - -We have a [development mailing list](https://htop.dev/mailinglist.html). Feel free to subscribe for release announcements or asking questions on the development of `htop`. - -You can also join our IRC channel [#htop on Libera.Chat](https://web.libera.chat/#htop) and talk to the developers there. - -If you have found an issue within the source of `htop`, please check whether this has already been reported in our [GitHub issue tracker](https://github.com/htop-dev/htop/issues). -If not, please file a new issue describing the problem you have found, the potential location in the source code you are referring to and a possible fix if available. - -## History - -`htop` was invented, developed and maintained by [Hisham Muhammad](https://hisham.hm/) from 2004 to 2019. His [legacy repository](https://github.com/hishamhm/htop/) has been archived to preserve the history. - -In 2020 a [team](https://github.com/orgs/htop-dev/people) took over the development amicably and continues to maintain `htop` collaboratively. - -## License - -GNU General Public License, version 2 (GPL-2.0) or, at your option, any later version. diff --git a/README b/README new file mode 120000 index 00000000..42061c01 --- /dev/null +++ b/README @@ -0,0 +1 @@ +README.md \ No newline at end of file -- cgit v1.2.3
