I copied a .rar file from a Windows to a Linux machine using WINSCP tool.
After copying the file, I tried to extract the .rar file, but I wasn't successful.
I tried using unrar and file.rar.
I got this error:
Unknown command on to putty console.
Please tell me how to extract the RAR file in the same directory.

unrarisn't installed on the Linux machine. Can you install it? – birryree Oct 11 '11 at 18:05
