+===== Find folders with the most files =====
 If you run into a situation in which you have high inode usage as seen by 'df -i', the following syntax will show folders with the most files:
 <code bash>
-nice find / -mount -printf '%h\n' | sort | uniq -c | sort -k 1 -n
+nice find / -mount -printf '%h\n' | sort | uniq -c | sort -n -k 1

   * find / = start in the "/" directory (change this to the root of a mount point you wish to investigate as identified by 'df -i')
   * mount = Do not descend directories on other file systems.

+  * printf '%h\n' = Print the leading directories of a file's name (%h), then a newline (\n). (man find, then search for 'printf\ format' to see all available formats)
   * sort = Default sort by starting of line alphabetical
   * uniq -c = Filter matching adjacent lines, prefix lines with the count of occurrences
-  * sort -k 1 -n = Sort via the "key" starting at 1 (field 1, the number) numerically
+  * sort -n -k 1 = Sort numerically (-n) via the "key" (-k) at field 1 (field 1 is the count from 'uniq -c').
 This will give output with the first column displaying file count and the second column displaying the folder it is in.
