How to enter text at command prompt from shell script without executing command?

Is there a way to have a shell script output text at the command prompt WITHOUT issuing the command?

CONTEXT: I SSH into a particular machine several times a day, and about 80% of the time, I type the same three commands as soon as I login. I would just put these commands in my .bashrc, but 20% of the time, I do NOT want to issue these commands. I'm wondering if there is some command I can put in .bashrc that will automatically put a string at my command line, so that when I login I see:

$ cd some/dir && ./some_script.sh

I could then just press enter 80% of the time or just clear the text the other 20% of the time.

(Inspired by Abdul Rehman's answer.)

Put this as the last line in your .bashrc file:

read -e -p "(Control-C to cancel) $ " -i "cd some/dir && ./some_script.sh" && eval "$REPLY"

• read -e lets you enter a string using Readline for editing.
• The -p provides a pseudo-prompt for this one-time command.
• The -i provides a default string which you can edit or hit Enter to accept.

If you hit Enter, read sets the value of REPLY and exits with status 0, causing the following eval to execute. (Usually, eval is not a good command to use; however, here you would be presented with an interactive shell anyway, so there's not much risk here.) If you type Control-C instead, read exits with status 1 and the following eval is not executed, leaving you at your command prompt.
