Find and replace @n with a something else

Question

I'm trying to replace &00 with @n in a bunch of documents. Done a bit of digging, but truthfully I'm not great with perl. I tried added a few escape characters, and a few other things. How could I get the below command to work? It does not seem to like me replacing @n (for obvious reasons).

perl -pi -w -e 's/&00/@n/g;' *.wld

Thanks

The @n refers to an array, which is empty. When an empty array is interpolated, the result is the empty string. Therefore, your command would seem to delete all &00 occurrences.

Escaping the @ should help here:

perl -i -wpe's/&00/\@n/g' *.wld

(flags that don't take an argument can be stacked)

"flags that dont take an argument can be stacked"?

@TLP As in, perl -p -w -> perl -pw

Aha... yes, but "flags" in this case are called "switches".

@user2612011: find /all /needed /directories -type f -name \*.wld | xargs perl <...> find(1) searches for files, recursively. xargs(1) runs whatever command + arguments read from stdin.
