This is a shell command to find and replace over multiple files recursively in MacOS.
This is surprisingly difficult to figure out how to do. There are many options an nuances. This may work for your particular OS version, Terminal, Shell, and installed tools. Lol, what a disclaimer!
Anywho, the command that works for me at this moment is:
fd -0 package.json ** | xargs -0 sed -i "" "s/npm run/yarn/g"
Let’s break it down:
fdis an alternative to the unix
findcommand. It looks for files that match the name given.
package.jsonis the name of the file we’re looking for.
-0is an option to
fdthat preps it for
xargslater. It puts results on one line, separating them with NULL characters.
fdto checkout all the directories listed at this level. It’s recursive by default.
|is a pipe that connects and forwards commands.
xargsis a command that takes the output of the previous command and appends it to the next command

-0and makes the connected commands compatible.
sedis a string replace command. The options and args that follow feed into it

s/npm run/yarn/gThis is the string to find (indicated by
s/) and replace (ie, change “npm run” for “yarn”) globally (indicated by the
So there it is. Save that one to your cranium.
While searching for how to perform this command, I came across a great tool that will expose the
man pages for much of this in a combined web gui, called explainshell.com. Pretty cool!
What other solutions for search and replace have you used on MacOS?
