Suppose I file 'a1.txt' and 'a2.txt' in my current directory. When I type 'cat a' then TAB, it will show me 'a1.txt' and 'a2.txt'. If I type TAB repeatedly, it will always show me the same thing.
However, a better response might be 1. complete the command to 'cat a1.txt' at the 2nd TAB, 2. complete the command to 'cat a2.txt' at the 3rd TAB, 3. return to the original 'cat a' at the 4th TAB, 4. complete the command to 'cat a1.txt' again at the 5th TAB. I'm wondering if there is a way to configure bash this way.
