I tried to make a DOS emulator.
I am having problem in executing the 'cd <directory_name>' command.
There is some problem in 'cutcmd2'. It is supposed to be 'cd' but it always empty.
I made two files in ~/Documents ---> file1, file2.
But when I execute this script...another file with the name 'file1?' is created which I guess is the problem...!!!
Please help...!!!!!ASAP
Problem in running DOS emulator ...!!!!!
