Any clue as to what's my blocker in an attempt to run an external process via groovy on windows 2003?
When I execute "wmic process get processid" on commandline with same path as groovy exec this works producing output. On winserver 2008, this works. On 2003 it doesn't even if I add "cmd /c ..." I also tried using "wmic quit" and I continue to get a non zero result code. So, I don't think groovy can exec wmic on this version of windows.
I'm baffled as to what is different between the two environments.
StringBuffer output = new StringBuffer()
StringBuffer err = new StringBuffer()
def process = "wmic process get processid".execute()
process.consumeProcessOutput(output,err)
process.waitForOrKill(7000)
println "Output:\n${output.size()}\nErr:\n${err.size()}\n${output}\n${err}"

I am trying to escape the "$" symbol when executing a echo $! command in java.
static def execSync(String command) throws Exception {
log.info("exec(" + command + ")")
String[] splited = command.split("\\s+")
def listCommand = Arrays.asList(splited)
ProcessBuilder processBuilder = new ProcessBuilder()
processBuilder.command(listCommand)
return processBuilder.start()
}
execSync("echo \$!") // returns $! when i'd like a pid
I have identified the problem to be in the command that is executed (ie: the code above) and not from my way of getting the stdout of the command (outputstream blabla). If your are absolutely sure it's not, i'll show more.
When i execute on my system (centOs 7) "echo $!" i obviously get a pid, for instance : 2626.
I would mostly like to know if there is a way to do a "echo $!" like on the system with a string in my function ? (regex or other stuff)
Otherwise,
ProcessBuilder.start returns a Process but doesn't seem to have a method to get the pid, only exitReturn, out/in/error stream... Since I execute the previous command with the method shown above, i though i could get the pid with a linux command.
So, is there a way to get the pid of the previous process ? (not realy what i seek but i can manage if there is no other way)
I'm stuck with java 8, when java 9 has a method "getPid"
If you .execute() or use the ProcessBuilder directly, you can not directly use shell features. It just allows to spawn processes with arguments. You have to start a shell and make it execute your shell "script" (command). E.g.
def listCommand = ["/bin/sh", "-c", command]
So I'm trying to run a shell script on an automated SoapUI project which is execute in continuous integration. I need to send a few parameters and an SQL query to the script so I'm trying to execute a command similar to this:
/path/to/file.sh param1 param2 "sql query"
If I log the command and execute it manually it works perfectly but when groovy runs it the "sql query" argument is split into multiple arguments for every space.
I've tried running the command with
String command = "/path/to/file.sh param1 param2 \"sql query\""
def proc = command.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(5000)
I'm not getting what I'm doing wrong.
Best regards
In Grooy also arrays (arrays are internal lists) have a execute method. It's usually much safer to execute commands over arrays.
def command = ['/path/to/file.sh', 'param1', 'param2', 'sql query']
def proc = command.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(5000)
while this line works fine on windows on my linux box it returns exit code 1.
"gnuplot -e \"set output '${imageFile.toString()}'; filename='${dataFile.toString()}'; ${args}\" \"${plotFile.toString()}\"".execute()
But if I execute just this from the terminal everything works.
gnuplot -e "set output '/tmp/hrp-current.jpg'; filename='/tmp/a731265b-3736-4bb9-acf4-b92c1a09b999.csv'; " "/tmp/hrp/build/groovy/../gnuplot/hrp-current.gnuplot"
What am I missing here? It somehow has to do with the fact that gnuplot writes to a file because `some_command > some.file" also fails on linux with exit code 1 while it would work fine on windows.
.execute() on a String just splits on whitespace. You also don't need to quote the params for execution (you need to that for the shell). So execute an list of params instead:
["gnuplot", "-e", "set output '${imageFile.toString()}'; filename='${dataFile.toString()}'; ${args}", plotFile.toString()].execute()
Indeed it is some file writing issue so I need gnuplot to pipe its outout to stdout and then consume it from my groovy script where I read the outputstream and then save it to a file:
def out = new ByteArrayOutputStream()
def err = new ByteArrayOutputStream()
process.waitForProcessOutput(out, err)
Using espeak command to generate an audio
espeak "Hello Mr. Toumi" --stdout > /tmp/audio123.wav
When i run this command using terminal , it works fine .
Prepare now in API for this command in Grails Service
#EspeakService.groovy
File speak(String message){
Process pr='espeak "'+message+'" --stdout > '+filePath(message);
pr.waitFor()
return new File(filePath(message));
}
When i run : espeakService.speak('Hello Mr. Toumi') , there is no file generated and also no error message displayed .
Any idea : Why does it not work programmatically ?
Java's external process execution mechanism is not a shell and doesn't support redirection using > like that. You should use a ProcessBuilder and do the redirection with that:
ProcessBuilder pb = new ProcessBuilder("espeak", message, "--stdout")
File out = new File(filePath(message))
pb.redirectOutput(out)
pb.redirectError(ProcessBuilder.Redirect.INHERIT)
pb.start().waitFor()
return out
redirections like > are done by shell. either use ['sh', '-c', 'espeak ...'].execute(). or just pick up the stdout from the process, which would save you from dealing with a file. e.g.
def p = "echo -n 666".execute()
p.waitFor()
assert p.in instanceof InputStream
assert p.in.text == "666"
I have a python script written using paramiko and pysphere.this script is in linnux box.i have some powershell scripts on windows machine which i have to run one after the other(after each script ends obviously),but the point here is through my pythonscript it is not running the powershell scripts on windows machine.Kindly help.
PS;i have to run python script fromlinux and powershell scriupts on windows.
Here is a snippet of code for running powershell scripts:
target_vm1 = connect_Esxi_Server(return_list[0])
print "Again connected to vm:" + return_list[0]
target_vm1.login_in_guest(vmUser,vmPass)
list_scripts = target_vm1.list_files(VM_SCRIPT_LOCATION)
for f in list_scripts:
size = f['size']
**if size <> 0:**
paths = f['path']
print paths
#for all_scripts in paths:
*****print "script running is :" , paths*****
path_l = os.path.join(VM_SCRIPT_LOCATION + '\\'+ paths)
*****print path_l*****
run_script =
subprocess.Popen([r'c:\\Windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe',". path_l"], shell=True)
result = run_script.wait()
print "result is:", result
I doubt whether subprocess will work.
Please note that the bold prints given above are giving the correct script to run.there are many powershell scriptsinside the fo;der,so looping throught it and running each one of them.
Any help would be appreciated,this thing is eating my heads off.....argghhhhhhhh..
Cheers,
NJ
I run powershell commands directly using paramiko:
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('10.10.0.2', username='vipul', password='password')
cmd = "powershell -InputFormat none -OutputFormat text echo Hello"
stdin, stdout, stderr = self.ssh.exec_command(cmd)
print stdout.readlines()
Here 10.10.0.2 is my windows machine. Using cygwin sshd server for ssh.
