| Introduction |
| ------------ |
| |
| This is `htop`, an interactive process viewer. |
| It requires `ncurses`. It is developed primarily on Linux, |
| but we also have code for running under FreeBSD and Mac OS X |
| (help and testing are wanted for these platforms!) |
| |
| This software has evolved considerably over the years, |
| and is reasonably complete, but there is always room for improvement. |
| |
| Comparison between `htop` and classic `top` |
| ------------------------------------------- |
| |
| * In `htop` you can scroll the list vertically and horizontally |
| to see all processes and full command lines. |
| * In `top` you are subject to a delay for each unassigned |
| key you press (especially annoying when multi-key escape |
| sequences are triggered by accident). |
| * `htop` starts faster (`top` seems to collect data for a while |
| before displaying anything). |
| * In `htop` you don't need to type the process number to |
| kill a process, in `top` you do. |
| * In `htop` you don't need to type the process number or |
| the priority value to renice a process, in `top` you do. |
| * In `htop` you can kill multiple processes at once. |
| * `top` is older, hence, more tested. |
| |
| Compilation instructions |
| ------------------------ |
| |
| This program is distributed as a standard autotools-based package. |
| See the [INSTALL](/INSTALL) file for detailed instructions. |
| |
| When compiling from a [release tarball](https://hisham.hm/htop/releases/), run: |
| |
| ./configure && make |
| |
| For compiling sources downloaded from the Git repository, run: |
| |
| ./autogen.sh && ./configure && make |
| |
| By default `make install` will install into `/usr/local`, for changing |
| the path use `./configure --prefix=/some/path`. |
| |
| See the manual page (`man htop`) or the on-line help ('F1' or 'h' |
| inside `htop`) for a list of supported key commands. |
| |
| If not all keys work check your curses configuration. |
