If I use "*" to copy all files, then command doesn't work why? If I try
copy single file then everything is ok.
String cmd ="/bin/cp /home/k/java/single.txt /var/www/k/";
Because "*" is only special to the shell, and you are not invoking a shell. In
your case the executable /bin/cp would try to copy a file called "*", and there
isn't one.
How to copy all files ? :/a
Invoke a shell:
String[] cmd ={"/bin/sh", "-c", "/bin/cp /home/k/java/* /var/www/k/"};
