df does not work on mountpoints that have a space in the name. Example: [root@genie home]# mount /dev/hdd "music cd 1"/ mount: block device /dev/hdd is write-protected, mounting read-only [root@genie home]# df Filesystem 1k-blocks Used Available Use% Mounted on /dev/hda2 4191269 3859883 331386 92% / df: /home/stuph/music\040cd\0401: No such file or directory [root@genie home]# I think this also affected Redhat 5.2.
Confirmed in test lab. Will work (sorta) if you directly quary the mount point and enclose it in quotes. Will get something like: Filesystem 1k-blocks Used Available Use% Mounted on df: /tmp/mount\040point: No such file or directory - 9717839 8773132 440459 95% /tmp/mount point
Fixed in fileutils-4.0-2 and later
