Rhel7 double quotes not escaping space


Hi,

I am running java code to execute linux command using:

if(System.getProperty("os.name").toLowerCase().startsWith("windows")){
cmd = "cmd /C %SMBASE%/util/formlib.exe -xf "+"""+file.getLocation().toString()+""";
} else if(System.getProperty("os.name").toLowerCase().startsWith("linux")){
cmd = _SMBASE+"/util/formlib -xf "+"""+file.getLocation().toString()+""";
}
String outputLocation = root+"/"+path+"/bin";
IProject project = file.getProject();
Process p = Runtime.getRuntime().exec(cmd,null,new File(outputLocation));

when file.getLocation is like /legacy/prod/sample.lib there is no problem with exec.
But when there is path like /legacy/my folder.sample.lib
I am getting error like:
No such folder error: /legacy/my

Why double quotes not not escaping spaces in path?

how is related to linux? You wanted to run a command on windows and it was not formatted properly.
I would try to check the content of the variable cmd and also find how to protect spaces using Runtime.getRuntime().exec

This is the code deal with linux

if(System.getProperty("os.name").toLowerCase().startsWith("linux")){
cmd = _SMBASE+"/util/formlib -xf "+"""+file.getLocation().toString()+""";
//cmd = /legacy/util/formlib -x /disk/home/rkasiraju/my folder/sample.lib

}

This editor taking "backslash"" as """
Could you please provide the sample?
