sed -i doesent work on MacOs (sed: 1) and work on linux

Question

I succeeded to use sed -i on Linux to modify a JSON value in a file.

$> sed -i '/brand/c\   \"brand\": \"'valueModified'\"' ./config/brand.config.json

But on MacOS I get:

sed: 1: "./config/brand.config.json": invalid command code .

I'm trying to use this command in a shell script on linux and macOS.

Thank you

Does `man sed` on the Mac mention the `-i` option at all? – choroba Mar 20 '18 at 10:22 — choroba, Mar 20 '18 at 10:22
On OSX use `sed -i.bak '...'` – anubhava Mar 20 '18 at 10:28 — anubhava, Mar 20 '18 at 10:28

POSIX sed implementations allow for the I line replacement where non-POSIX UNIX implementations do not. OSX, like BSD implentations can be accomplished like so :

cp -p ./config/brand.config.json ./config/brand.config.json.tmp;
sed '/brand/c\   \"brand\": \"'valueModified'\"' ./config/brand.config.json.tmp > ./config/brand.config.json
