[Bug Report] Error: No such file or directory (os error 2) because of "broken symbolic link"

[c02y]

>> fd -HI -p 'gtk' '/home/user/' | wc -l
2976
>> dua a (fd -HI -p 'gtk' '/home/user/')
Error: No such file or directory (os error 2)

>> fd -HI -p 'desktop' '/home/user/' | wc -l
1437
>> dua a (fd -HI -p 'desktop' '/home/user/')
# works normally, thousands of lines below

>> fd -HI -p 'adwaita' '/' | wc -l
5900
>> dua (fd -HI -p 'adwaita' '/')
# works normally, thousands of lines below

This is not always happening as you can see, depending on the keywords I pass, so I analysed all the file types in the list and noticed some files are "broken symbolic link to..."

So

>> fd -HI -p 'gtk' '/home/user/' | wc -l
2976
>> dua a (fd -HI -p 'gtk' '/home/user/')
Error: No such file or directory (os error 2)

>> fd -HI -p  'gtk' '/home/user/' -X file | rg -v 'broken symbolic link' | awk '{sub(":", "", $1); print $1}' | wc -l
2966
>> dua (fd -HI -p  'gtk' '/home/user/' -X file | rg -v 'broken symbolic link' | awk '{sub(":", "", $1); print $1}')
# works normally, thousands of lines below

>> fd -HI -p  'gtk' '/home/user/' -X file | rg 'broken symbolic link' | awk '{sub(":", "", $1); print $1}'

Thanks for a lot for letting me know.

The problem seems to be that it will completely fail if one root path on the command-line cannot be read. So dua a broken b will print nothing but a relatively undescriptive error message. Instead it should print at least the results for a, then <error> then the results for b.

dua i a broken b also doesn't come up even though I would expect it to showing at least a and b.

[c02y]

yeah, I have two solutions in mind:

1. Ignore those files/dirs if they can not be read just like some read permission issue in files/dirs such as /proc
2. simply do not read it and print the path (I'm not sure if this can be done easily)

Maybe provide a flag so dua ignores it or prints it.

Thanks for sharing! I think I have found a solution that works well with how these errors are usually handled.
You can take a look at the latest release.
