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