Thanks. Here's the complete code snippet
#!/usr/bin/env groovy
String cmd = $/
IFS=" " read -ra LINE <<< `ls -al | grep Music`
echo ${LINE[4]}
/$
StringBuilder outstr = new StringBuilder()
StringBuilder errstr = new StringBuilder()
Process proc = cmd.execute()
proc.waitForProcessOutput(outstr, errstr)
println $output
When I run it, I get
Caught: groovy.lang.MissingPropertyException: No such property: LINE for
class: file
groovy.lang.MissingPropertyException: No such property: LINE for class: file
at file.run(file.groovy:5)
