After a while without posts on the a bashism a week series, it is coming back!
Next week, at the usual time and day of the week, the series of blog posts about bashisms will be back for at least one more month. Subscribe via Atom and don't miss any post and check all the previous posts.
The a bashism a week series cover some of the differences between bash and the behavior of other shells, and the requirements by the POSIX standard regarding shell scripting. Or put simply: they are a guide to common bashisms, allowing you to identify them and avoid their use for a more compatible and portable code.
