从Grails启动命令行程序？

Question

I have a Grails application, which has a cron job that should start a command line process.

I know that with Gradle I can easily start a command line process, but I do not know how I can do that with Grails.

How can I start a command line process from my Grails/Groovy/Java application?

Answer 1

只是groovy http://groovy-lang.org/groovy-dev-kit.html#process-management ：

["touch", "/var/tmp/kilroy_was_here"].execute()

Answer 2

If you need more than one command in sequence you have to use:

def result = [ 'ksh', '-c', 'ls -ltr;cd ..;ls -ltr;exit' ].execute() 
println result.text 

def cmds = [ 'ls -ltr', 
               'cd ..', 
                         'ls -ltr', 
                         'exit' ] 
def result = [ 'ksh', '-c', cmds.join(";") ].execute() 
println result.text
