Greetings.
I am interested in opinions that people might have on how to quote
special characters in filenames in files in /proc.
The particular filenames of interest are those in
/proc/fs/nfs/exports
This file lists the directories that have been exported, what hosts
they are exported to, and what export options apply.
The lines are made of space-sparated fields. The first field is the
directory name.
So what happens when you export a directory which has a space in it's
name? Currently this doesn't work too well.
My preference is to replace all control characters, spaces, DEL, and '%'
with a %hex string much like the special character quoting in
URLs.
Other alternatives that I don't like is to preceed special characters
with '\' or to use =hex instead of %hex, like MIME encoding does.
So:
is there any good reason why I should choose something other than %hex?
is there any convention already used in some other part of the
kernel.
In the longer term it would probably be better to use a directory
rather than a file, and present all file names as symlinks so quoting
isn't needed. However I don't see that as a short term solution and I
think a short term solution is needed.
Thankyou for your time.
