Question

Next, type cd ro at the command prompt and press Tab. What is displayed on the screen and why? How many subdirectories under the root begin with “ro”?

Answer 1

Typing cd ro and then pressing tab will automatically complete the name of any subdirectories whicch begin with ro. For eg. in the system being used here, the current directory contains three subdirectories which begin with ro, names as ro_example, ro_example-Copy and ro_example-Copy(2).

Note:This will depend on the names of the directories of the system being used.

So. before pressing tab, the command prompt looks like this:

After pressing tab once, ro_example appears as follows:

After pressing tab once again, ro_example - Copy appears as follows:

After pressing tab one more time, ro_example - Copy(2) appears as follows:

If we press tab again, ro_example appears again (all subdirectories starting with ro had been listed and the cycle re-starts):

An up-vote/thumbs-up would be greatly appreciated!
