However, in the Ubuntu environment, the command only occurs once when we press the top arrow to use the prior command. It is identical when using git bash. Repeat these steps: Type "ls: in git bash. 2. Type "ls" once more. 3. To return to the previous command, use the top arrow. As you can see, the number of times we type the can command 'ls' does not matter; it only needs to occur once. This depends on how your shell is configured. Look into HISTCONTROL and ignoredups. You might want something like export HISTCONTROL=ignoredups in ~/.bashrc. Martin
