less-fork | less forked and optimized for use on POSIX SUSv3 systems

less-fork is a C library. less-fork has no bugs, it has no vulnerabilities and it has low support. However less-fork has a Non-SPDX License. You can download it from GitLab, GitHub.

This is a version of LESS, a file viewer, that has been modified heavily. It is based on Mark Nudelman's original program, Less v458. The original less is located at This version is modified to work better on POSIX systems, and uses APIs that older systems and non-POSIX platforms might lack. In many cases these newer APIs have improved safety or performance. It is also modified to substantially improve its compliance with the POSIX specifications when running as more. We believe that when called as more, less fully implements both Issue 6 and Issue 7 specified behaviors of the more utility. Finally, substantial effort has been invested to improve the readability and maintainability of the code, and to avoid reimplementing library functions found on standard systems. An incomplete list of changes is located in the file CHANGES.
