how to execute gunzip -c > outputfile command from java

[elay Raja]

I want to decompress the .gz file and put the decompressed file in another location by keeping original file(.gz) without any modification.

Line 1. Runtime run=Runtime.getRuntime();
Line 2. Process process=run.exec("/bin/gunzip -c /root/yy/fileName.gz >
/root/xx/fileName");
Line 3. process.waitFor();
Line 4. int val=process.exitValue();

The above command works fine in Linux terminal.But when i try to execute from runtime,it does not work. Is there any problem in code?It does not reach the Line 4.If i paste the above command in terminal,it works fine.
Please help me to resolve this issue.

You may need to handle the output streams as described here in this article.
