# dircomp
|
|
## Name
|
|
dircomp - A directory comparison tool
|
|
|
|
## Synopsis
|
|
`dircomp directory1 directory2 [-rvfdh]`
|
|
|
|
## Description
|
|
dircomp is a program for evaluating whether two directories are equivalent.
|
|
|
|
Two directories are considered to be equivalent if and only if these conditions apply:
|
|
* They have the same number of files and folders;
|
|
* For each file in a directory, there is the same file in the other. Two files are considered to be the same
|
|
if they have the same name, including extension, and same content;
|
|
* For each folder in a directory, there is a folder with the same name in the other.
|
|
|
|
If the recursive option is applied, then another condition must hold true:
|
|
* For each folder in a directory, there is an equivalent folder in the other, with the same name.
|
|
|
|
The options are as follows:
|
|
```
|
|
-r Recursive
|
|
-v Verbose
|
|
-f Fast. Halt as soon as the directories are found to be not equal
|
|
-d Comparison by digest
|
|
-h Print this help and quit
|
|
```
|

|
You can have a look at the code and at its [mathematical proof](https://github.com/xfarrow/dircomp/wiki/Mathematical-correctness-of-dircomp) to validate its correctness.
