The script is meant to be a small addition for the linux bash.

It makes the bash history more easily accessible than going through Cmd+R manually, by listing a number (default 20) of last commands. You can then just type the number of the command you would like to execute from the list.

It especially helps to get an overview of slightly different commands and makes it easier to select the right one.

Go to the cloned files and execute config.sh. When given no parameters, the script is given the system wide alias: rh (for: repeat history).

Otherwise you can specify the alias name as first argument to the config.sh script.

• ./config.sh [alias_name]

This appends the appropriate alias to your ~/.bashrc file.

You can alternately add it manually to your ~/.bashrc file (replace $PATH_TO_SCRIPT with the path to repeat_history.sh):

alias rh='history -a && . $PATH_TO_SCRIPT/repeat_history.sh'

rh [searchWord] [NumberOfMaxOptions]

This command is now system wide accessible by typing rh into the terminal.

The first argument to rh is the search word for the command, you want to execute. If no argument is given, the last 20 executed commands are shown.

The second argument to rh changes the number of options to show.

Some screenshots to see how it looks like.

Example of rh without selection:

• Remove duplicates from the list so it is not spammed with the same command.
• Add usage and help output.
