lsof-org at GitHub
The lsof-org team at GitHub takes over the maintainership of lsof originally developed and maintained by Vic Abell. This repository is for maintaining the final source tree of lsof inherited from Vic. "legacy" branch keeps the original source tree. We will not introduce any changes to the "legacy" branch. This branch is just for reference.
"master" branch is used for maintenance. Bug fixes and enhancements go to "master" branch.
lsof had supported many OSes. A term "dialect" represents code for supporting OSes. Because of limited resources, we will maintain the part of them. The current status of maintenance is as follows:
- freebsd
- partially maintained, but testing on Cirrus CI is temporary disabled
- linux
- fully maintained, and tested on Travis CI
- darwin
- not maintained, but partially tested on Travis CI
If you are interested in maintaining a dialect, let us know via the issue tracker of GitHub (https://github.com/lsof-org/lsof/issues). If we cannot find a volunteer for a dialect, we will remove the dialect.
Many texts in the source tree still refers purdue.edu as the home of lsof development. It should be https://github.com/lsof-org/lsof, the new home. The updating is in progress.
We ran another repository, lsof-org/"lsof-linux" derived from lsof-4.91 that was also released by Vic. The repository is no more used; all the changes made in the repository are now in lsof-org/"lsof" repository.
