btw, 320:-1 means width is 320px and height would be set automatically

Functions: sudo

Delete a certificate from the macOS security keychain

Use `security list-keychains` to find possible keychains, and `security dump-keychain` to look for certificates.

`sudo security delete-certificate` without arguments shows options for removing: by common name or by SHA-1 hash.

This is especially useful if a certificate locks up Keychain Access.app, which happens for certificates with many SANs in macOS 10.12.

ShellCheck all the bash/sh script under a specific directory excluding version control

This is a commodity one-liner that uses ShellCheck to assure some quality on bash and sh scripts under a specific directory. It ignores the files in .git directory.

Just substitute "./.git/*" with "./.svn/*" for older and booring centralized version control.

Just substitute ShellCheck with "rm" if your scripts are crap and you want to get rid of them :)
