Overview

shellquote quotes strings for shell scripts.

Sometimes you get strings from the internet and need to quote them for security, other times you'll need to quote your own strings because doing it by hand is just too much work.

Another option is http://github.com/kballard/go-shellquote. The quoting algorithms are completely different and the results vary as well, but both produce working results in my brief testing. See https://github.com/frioux/go-scraps/tree/master/cmd/quotetest for a tool that shows the results of quoting with each package.

Example

Code:

fmt.Println("#!/bin/sh")
fmt.Println("")
quoted, err := shellquote.Quote(os.Args[1:])
if err != nil {
    fmt.Fprintf(os.Stderr, "Couldn't quote input: %s\n", err)
    os.Exit(1)
}
// error won't happen if the first input didn't error
doublequoted, _ := shellquote.Quote([]string{quoted})
fmt.Println("ssh superserver", doublequoted)
