Skip unreadable files in awk scripts

Have you ever needed to give awk multiple files to process, but wanted it to skip files that it can’t open? Use this snippet!

BEGINFILE {
    # skip files that cannot be opened
    if ( ERRNO != "" ) {
        nextfile
    }
}

This trick is mentioned in the documentation for the BEGINFILE pattern, but not spelled out as code. You’re welcome. 😀

Unsafe Chrome Sometimes Necessary

In my work – every now and then – I found myself in need of a browser with reduced security checks (mainly to gloss over cross domain XMLHttpRequests and SSL certificate violations) for testing purposes. I didn’t want to take the risk and use my main browser session with these settings, so I made me a script (also available as a Gist). 🙂

Tip:
If you use oh my ZSH you can save this file in 

~/.oh-my-zsh/custom/plugins/chrome-unsafe/chrome-unsafe.plugin.zsh

and add “chrome-unsafe” to your list of used plugins in 

~/.zshrc
