What do you want matched? Without the quotemeta it would match "fileAtxt",
this is not normally the behavior you desire. Basically it all comes down
to this: always use quotemeta unless the variable is known to contain the
string form of a regex. Also, it is a good idea to note the end of the
quotemeta like this
s/\Q${search}\E/replace/
