Be very careful using bdf. It has a very annoying behavior where long source paths for filesystems will cause split lines and mess up any scripting. Almost all NFS or Samba/CIFS shared filesystems will exhibit this problem.
Use the attached bdfmegs script. bdfmegs will never split a line and can report in MB or GB. You'll find the -P and -q options very useful. For example:
bdfmegs -qP 95
will show all filesystems that are 95% full or more. The -q leaves off the header so scripting is easier. Just store bdfmegs on each server and then run the script on each server with ssh and capture the result. Here are the options:
Usage: bdfmegs [ -glPpqstvu ] [ dir(s) or file(s) ]
where:
-g = gigabytes rather than megabytes
-l = local only (not NFS)
-p ## = highlight pct -ge ##
-P ## = same as -p but show only pct -ge ##
-q = suppress the header line and no char enhancements
-s = summary of total, used and available
-t xxxx = specifc filesystem (hfs vxfs nfs cdfs cifs autofs DevFS)
-u = usage details (return code = 0, usage text to stdout)
-v = verbose (shows FSversion, largefiles flag)
(requires read permission for mountpoint)
File(s) or dirpath(s) may be specified to limit
the output of bdfmegs as in:
bdfmegs -vlg /usr/contrib/bin /var/tmp
If bdfmegs is run as bdfgigs (ie, a link), then -g is default.
