OK, after hours of searching online I have broken down and I am asking for help here. I have an IBM server running Ubuntu 12.10. I remote in using putty. When I type commands at the command line using putty I can use 'tab' to autocomplete both file names and directories. But when I use screen, even if I source ~/.bashrc (I am using bash), I can only autocomplete directories not filenames. The <tab> autocomplete function does not even recognize the files that are there and will only give directory names when I <tab><tab>. Can't figure it out. Really bizarre. Any suggestions appreciated!
