-====== Find ====== 
  
-**General Information** 
- 
-The GNU find utility and some useful parsing methods. 
- 
-**Checklist** 
-  * Distro(s): Any

- 
-===== General Syntax ===== 
- 
-The general syntax of find is: 
- 
-<code bash> 
-find [options] [path] [expression] 
-</code> 
-The [options] allow for how to treat symbolic links, debugging, and optimization.\\ 
-The defaults are almost always used. (see 'man find' if curious) 
- 
-[path] is the directory in which you are starting the search. 
- 
-[expression]s are made up of options that manipulate the operation of find. 
-

- 
-===== Find Examples ===== 
- 
-Some of the useful find commands that have been "tested in production". 
- 
----- 
- 
-==== 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 -n -k 1 
-</code> 
- 
-Explanation: 
-  * nice = Use nice in a production environment to lower CPU scheduling priority by a default of 10, as find can be CPU intensive 
-  * 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 -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. 
- 
-Example Output (last 5 lines): 
-<code bash> 
-   1814 /usr/bin 
-   1983 /usr/share/doc 
-   2075 /usr/share/man/man3 
-   2122 /usr/share/linuxmint/mintinstall/installed 
-   2123 /usr/share/linuxmint/mintinstall/icons
