# ncdu-compare
Compare ncdu export files and shows differences to find out what consumes most space.
## Installation
~~~
# from pypi
pip3 install ncdu-compare
# ... or from git
pip3 install git+https://github.com/yaroslaff/ncdu-compare.git
~~~
## Example usage
Create ncdu snapshots with command:
~~~bash
# now
$ ncdu /some/path/ -0o /tmp/snapshot-1
# after some time, e.g. daily
$ ncdu /some/path/ -0o /tmp/snapshot-2
~~~
Compare it
~~~bash
$ ncdu-compare /tmp/snapshot-1 /tmp/snapshot-2 | sort -n | tail -n 5
~~~
Example real output (first number is growth in bytes for `sort -n`, may be negative):

## Invalid unicode filenames
Sometimes ncdu can produce invalid JSON files (see https://dev.yorhel.nl/ncdu/jsonfmt). When loading ncdu files ncdu-compare uses (default) 'replace' mode to handle unicode errors. You can override it with `-e`/`--error` options, e.g. `--error ignore`. More at python doc to [open()](https://docs.python.org/3/library/functions.html#open).
