Owncloud log formatting with vim

owncloud-log-formatting-explanation.md

This is meant as a help if you want to have better readable Owncloud log entries. First navigate to the directory of your owncloud.log and download the vimcommands.txt down below with

wget https://gist.githubusercontent.com/benediktg/39ef9fbe0be8ae671d345d1fa4c0c781/raw/vimcommands.txt

Then execute

vim -s vimcommands.txt -u NONE - < owncloud.log

for the whole file or

tail -n1 owncloud.log | vim -s vimcommands.txt -u NONE -

for just the last entry.

After that you should see a kind of properly indented JSON file. In a final step note that you have to quit vim with :q! ;-)
