Re-Use A Bash Command With Different Parameters

Suppose you have typed and executed this command in your Linux shell:

Now you want to run the same command, but with 2.34 instead of 1.23
A nice way to do it is this:

Meaning, run the last command (!! is also called ‘bang bang’, and it’s substituted by the last command you executed), and replace every instance of 1.23 by 2.34

via Unix Bash Scripting.
Have fun
