| # Introduction | |
| Today I will introduce you to Diffoscope, a command line software to | |
| compare two directories. I find it very useful when looking for | |
| changes between two extracted tarballs, I use it to compare changes | |
| between two version of a program to see what changed. | |
| Diffoscope project website | |
| # How to install | |
| On OpenBSD you can use "pkg_add diffoscope", on other systems you may | |
| have a package for it, but it could be installed via pip too. | |
| # Usage | |
| It is really easy to use, as parameter give the two directories you | |
| want to compare, diffoscope will then show the uid, gid, permissions, | |
| modification/creation/access time changes between the two directories. | |
| The output on a simple example looks like the following: | |
| ```diffoscope output | |
| --- t/ | |
| +++ a/ | |
| │ --- t/foo | |
| ├── +++ a/foo | |
| │ @@ -1 +1 @@ | |
| │ -hello | |
| │ +not hello | |
| │ ├── stat {} | |
| │ │ @@ -1 +1 @@ | |
| │ │ -1043 492483 -rw-r--r-- 1 solene wheel 1973218 6 "Mar 20 18:31:08 2021"… | |
| │ │ +1043 77762 -rw-r--r-- 1 solene wheel 314338 10 "Mar 20 18:31:08 2021" … | |
| ``` | |
| Diffoscope has many flags, if you want to only compare the directories | |
| content, you have to use "--exclude-directory-metadata yes". | |
| Using the same example as previously with --exclude-directory-metadata | |
| yes, it looks like: | |
| ```diffoscope output without directories metadata | |
| --- t/ | |
| +++ a/ | |
| │ --- t/foo | |
| ├── +++ a/foo | |
| │ @@ -1 +1 @@ | |
| │ -hello | |
| │ +not hello | |
| ``` |
