How can I view the content of a file (on a Unix server) when I log into Unix from the Windows command prompt in FTP mode? I tried vi,cat and ed but none of them works.I can view the files using ls -l, but can't view the content. If there is any special command please let me know.
You can not run VI and cat over a FTP client. You want to log into the unix box with SSH and then use VI and/or cat.
FTP is for file transfers only.
SSH allows for command line functions. Editing and viewing of files on the server.
