Once I wrote a global search and replace ...

... and now I find that a simple bit of unix command line replaces hundreds of lines of MoonRock BASIC.

$ for x in *.chk; do cat $x | sed -e s/Database=/Filename=/ > tmp; mv tmp $x; done

Get every file ending in .chk, pipe it through sed to change the relevant string, capture the result into a temporary file and then copy it over the original.

    At least with the GNU sed you can skip the move step (using inplace editing).
    The original file content will be stored in .bak file:

    for x in *.chk
    do
    sed \
    -i.bak \
    -e 's+Database=+Filename=+g' $x
    done
