s/pattern/pattern/g on the commandline ?

[meino.cramer@xxxxxx]

Hi,

suppose I have very long and ugly commandline like this one:

    cat file\ from\ \#windows \ part1 \a.txt file\ from\ \#windows \ part2 \a.txt file\ from\ \#windows \ part3 \a.txt file\ from\ \#windows \ part4 \a.txt > allAbout_a.txt


and after summiting this ugly line I want redo the same but with a
slightly differen input like this:


    cat file\ from\ \#windows \ part1 \b.txt file\ from\ \#windows \ part2 \b.txt file\ from\ \#windows \ part3 \b.txt file\ from\ \#windows \ part4 \b.txt > allAbout_b.txt


which is - by the way - simply done with vim, with which I am editing
this posting currently.

My question is:
Is there any way to submit commands like 's/<searched>/<replacement>/g' for being applied the whole commandline in one go?

Thank you very much in advance for any help!
have a nice weekend!
Best regards,
mcc
