Re: Issue with the man page

[EricZolf]

Hello again,

I've installed fish and called the following:


$ python /usr/share/fish/tools/create_manpage_completions.py
/usr/share/man/man1/rdiff-backup.1.gz
$ ll ~/.local/share/fish/generated_completions/
total 12
-rw-rw-r--. 1 myuser myuser 9936 Oct 27 07:18 rdiff-backup.fish
$ cat ~/.local/share/fish/generated_completions/rdiff-backup.fish
# rdiff-backup
# Autogenerated from man page /usr/share/man/man1/rdiff-backup.1.gz
complete -c rdiff-backup -l allow-duplicate-timestamps --description
'This option is only to be used if you encounter the issue of metadata
mirrors…'
complete -c rdiff-backup -s b -l backup-mode --description 'Force backup
mode even if first argument appears to be an increment or mirror…'
complete -c rdiff-backup -l calculate-average --description 'Enter
calculate average mode.'
[... etc, 83 lines in total ...]


So it sounds to me like it works correctly. Fedora 32, rdiff-backup
2.0.5, fish 3.1.2
