Subject: suggestion to avoid erroneous lines in findmnt/lslocks/...
Date: Sat, 04 Aug 2012 16:42:10 +0100 [thread overview]
Message-ID: <501D42D2.6050904@draigBrady.com> (raw)
There was a recent change in df in coreutils to sanitize output of paths:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=3ed70fd
The essential issue fixed there is that control chars in a path will be
converted to '?' (this works in all locales), and doing so will mean
'\n' for example is not output. You could even consider this a potential
security improvement so that arbitrary users couldn't influence the
output of these commands for all users.
I suggest using the simple inplace replacement function from above.
cheers,
Pádraig.
