From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: With the default naming scheme of /dev/mapper/VolGroup00-XXX, filesystem names are too long for normal df output. For example, on my beta machine I currently have: Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-RootVol00 12901520 5648944 6597216 47% / /dev/sda1 101086 31750 64117 34% /boot none 517016 0 517016 0% /dev/shm /dev/mapper/VolGroup00-HomeVol02 2031952 70888 1857848 4% /home /dev/mapper/VolGroup00-LocalVol04 7063480 4203728 2500944 63% /usr/local /dev/mapper/VolGroup00-VarVol03 2031952 758128 1170608 40% /var This messes up automated tools that expect df output to be one-line-per-filesystem, such as the BigBrother monitor or LogWatch (on by default in RHEL4b2) which shows the nearly useless output: ------------------ Disk Space -------------------- /dev/mapper/VolGroup00-RootVol00 /dev/sda1 99M 32M 63M 34% /boot /dev/mapper/VolGroup00-HomeVol02 /dev/mapper/VolGroup00-LocalVol04 /dev/mapper/VolGroup00-VarVol03 df should use more intelligent columns to fit it on 80 char if possible, or perhaps truncate filesystem names unless a --verbose flag is set. Version-Release number of selected component (if applicable): coreutils-5.2.1-31 How reproducible: Always Steps to Reproduce: 1. Install RHEL3b2 with default filesystem names 2. Run df 3. See output Actual Results: df output split Expected Results: df output one-filesystem-per-line Additional info:
Use df -P for POSIX format.
'df -P' will resolve this issue for you.
