How can I use Groovy to execute a shell command that has backticks?

I’m unable to use Groovy to execute a shell command that has backticks. A simplified example:

println "echo `date`".execute().text

I searched around and tried to figure out how to escape them somehow, but without luck.

Solution

  • What happens if you try:

    println ["bash", "-c", "echo `date`"].execute().text

    My guess would be that with 

    "echo `date`".execute()

    java's Runtime#exec(String) would be used underneath, if you were calling execute() on a String. In which case, this simply tokenizes the string and executes the program echo with the argument

    `date`

    or

    $(date)

    but that's shell (bash) syntax, and must be executed via bash.
