Public bug reported:
I notice this issue today (2010/08/19) with Ubuntu-10.04
which really puzzles me. Ubuntu-10.04 was working fine until now.
Shell redirection creates junk characters in file names.
Here is an example:
$ mkdir /tmp/test
$ cd /tmp/test
$ echo > abc
$ mv abc def
mv: cannot stat `abc': No such file or directory
# Clearly this is wrong, I the 'mv' command should have succeeded.
$ ls
abc
# notice there there is a blank in front of the file name?!?
$ ls -Q
" abc"
Piping command is also broken:
$ ls | cat
cat: command not found
I though it might be a bug in bash, so I tried with another shell (zsh)
and the problem is identical. So is this a kernel problem or a file system
issue?
Here is more info:
$ uname -a
Linux pel-laptop 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 06:07:29 UTC 2010
i686 GNU/Linux
$ mount
...
/dev/sda1 on / type ext4 (rw,errors=remount-ro)
$ locale
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
If I change the locale to C, I see this:
$ export LANG=C
$ ls
??abc
And with C locale, piping works so I can pipe into sed to see what
kind of junk char are in the file name:
$ ls | sed l
\302\240abc$
abc
However, redirecting is still broken with C locale:
$ echo > yyy
$ ls
??abc ??yyy
I have no idea why those characters \302\240 end up in the file name
when redirecting.
Right now, I pretty much can't do anything in the shell anymore so
bug is severe.
