We're losing the art of bash ``` find -type f -iname '*.go' | xargs -r -n1 sed -i 's,foo,foobar,g' ```

Why use `xargs` instead of `-exec`? And if you do need `xargs` (for example, for parallel processing with `-P`), it is recommended to use `-print0` with `find` and `-0` with `xargs` to avoid issues due to filenames.

xargs passes many inputs to one script invocation, so even with a single thread there is often a dramatic speedup.

(and agree re -print0/-0, it's absolutely essential)

`find` can do that as well with `{} +` (at least, the `GNU` implementation and it'll automatically add more invocations if there are just way too many files).

In any case, OP was using `-n1` which means one file per invocation.
