   3 # check_inodes.pl for FreeBSD
   4 # Designed on FreeBSD 4.6 (although this should not matter)
   5 # parses df output, splits, and then takes variables
   6 # df.pl -f mountpoint -w warningnumber -c critical number
   7 # USE NUMBERS AND NOT PERCENTS FOR wanring and critical values
   8 # -h is help
   9 # -v is version
  10 # Mountpoints:
  11 # like / or /usr or /var (whatever you mount drives NOT the device names)
