coldfusion - Execute shell commands with arguments with `java.lang.ProcessBuilder` -

i have following script executes shell command java's java.lang.processbuilder works ok if don't use arguments:

<cfif isdefined("form.cmd")>   <cfif server.os.name contains "mac" or server.os.name contains "linux" or server.os.name "unix">     <cfset cmd = "sh -c #form.cmd#">   <cfelseif server.os.name contains "windows">     <cfset cmd = "cmd.exe /c #form.cmd#">   <cfelse>     <cfset cmd = "sh -c #form.cmd#">   </cfif>    <cfscript>     str = htmleditformat(rereplace(cmd,"""","'","all"));     exec = str.split(" ");     pb = createobject("java","java.lang.processbuilder").init(exec);     pb.redirecterrorstream(true);     proc = pb.start();     proc.waitfor();     isr = createobject("java","java.io.inputstreamreader").init(proc.getinputstream());     br = createobject("java","java.io.bufferedreader").init(isr);     line = br.readline();     while (isdefined("line")) {      writeoutput(line & '<br>');      line = br.readline();     }     br.close();     isr.close();   </cfscript> </cfif> 

if #form.cmd# uname, output expect:

linux

but if #form.cmd# uname -a scripts executes uname leaving outside -a argument. thought use java array add arguments:

  <cfscript>     args = createobject("java", "java.util.arraylist").init();     args.add("sh");     args.add("-c");     args.add("uname");     args.add("-a");     pb = createobject("java","java.lang.processbuilder").init(args);     pb.redirecterrorstream(true);     proc = pb.start();     proc.waitfor();     isr = createobject("java","java.io.inputstreamreader").init(proc.getinputstream());     br = createobject("java","java.io.bufferedreader").init(isr);     line = br.readline();     while (isdefined("line")) {      writeoutput(line & '<br>');      line = br.readline();     }     br.close();     isr.close();   </cfscript> 

same problem. doing wrong?

"-a" being passed in argument sh, not uname. need put "uname -a" within same arg, ie:

args.add("sh"); args.add("-c"); args.add("uname -a"); 

if helps clarify, directly command line, want type:

sh -c "uname -a"
