Can I use a flag like -l from ls with find or locate?

Not just for "ls -l" but for whatever action you'd want to perform to your locate or find results you can use xargs or in the case of find the -exec flag. Here are examples to achieve what you want to do:

In the case of locate you can use xargs:

locate something | xargs ls -l

Xargs can be used for find too, but find has the -exec flag that allow to optimize further actions with find results; for example

find . -iname something -exec ls -l '{}' \;

I am not sure what you want to do, but try

find . -ls 

You can use -printf and a suitable format string

 find ./ -printf "%M\t%n\t%u\t%g\t%s\t%t%f\n"

• %M Symbolic permissions
• %n hard links
• %u username or numeric user id
• %g group name or numeric group id
• %s file size in bytes
• %t last modification time
• %f filename
