FreeBSD cleanup all iocage

Finally I converted my internal sever to Bastille as jail manager. (I was using iocage). (https://bastillebsd.org)
To completely remove all stuff from iocage, you can run the following command:

iocage clean -a

Then delete the package

pkg delete py38-iocage

Iocage thank you for managing my jails for many year!
(I'm still using you on several other servers)

View content of all files including filename

In this example I get the ruby-version of my projects.

tail -n +1 */.ruby-version

Which results in the following output

==> project1/.ruby-version <==
2.5.1

==> project2/.ruby-version <==
3.0.0

==> project3/.ruby-version <==
2.7.2

Nice syntax each_with_index for hash

Just found out this Ruby syntax, for iterating over a hash (with an index).

hash.each_with_index { |(key,value), index| ... }

Cleanup OS X crap on network drive

find . \( -name ".DS_Store" -or -name ".Trashes" -or -name "._*" -or -name ".TemporaryItems" \) -print

Check if the print is correct. When the file can be deleted. replace '-print' with '-delete'

Prevent ._ file creation (samba config)

[share-name]

  veto files = /._*/.DS_Store/
  delete veto files = yes
