String cmd = /$
What you want to shell out and execute here
Remember, java shells out as sh, not bash or your shell of choice
/$
// output and error can be any class that implements Appendable
StringBuilder output = new StringBuilder()
StringBuilder error = new StringBuilder ()
Process proc = cmd.execute()
proc.waitForProcessOutput(output, error)
println proc.exitValue()

Subject: Running a shell script with return value?
Inside groovy, I want to write a shell script that parses the output of some
shell command and get some string value back. How can I get the value of the
shell command?
For example say I want to get the file size of some_file, I'll do
x = sh returnStatus: true, script: '''
IFS=" " read -ra LINE <<< `ls -al | grep some_file`
echo ${LINE[4]}
'''
How can I store the value of ${LINE[4]} in a groovy variable to use later?
Thanks,
Chris
