Loadable builtins are quite mature at bash version 5.2.37(1)-release (x86_64-redhat-linux-gnu). But Fedora ships without the /usr/lib/bash/ directory where bash's make install puts the binaries. Although the sources reside in the examples/loadables/ directory, the distributed ones are supported. Debian & Ubuntu provide the loadable builtins in a package called "bash-builtins". Slackware comes with loadable builtins installed as part of bash. I suggest Fedora takes one of the above approaches. Historical Note: Loadable builtins first appeared in bash 2.0. Binaries (what Fedora still lacks) appeared in bash 4.4. Reproducible: Always Steps to Reproduce: 1. $ enable -f finfo finfo 2. 3. Actual Results: -bash: enable: cannot open shared object finfo: finfo: cannot open shared object file: No such file or directory $ Expected Results: $ Additional Information: `help finfo` should now give you: finfo: finfo [-acdgiflmnopsuACGMPU] file [file...] Display information about file attributes. (and lots more)
It turns out that bash creates the binary loadable builtins during `make install`.
This message is a reminder that Fedora Linux 42 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13.
