rename all *.js files containing React markup to *.jsx

renameReactJsToJsx.sh

# finds all *.js files that have either `</` or `/>` tags in them and renames them to *.jsx
find ./src -type f -name '*.js' -not -name '*.jsx' -not -name '*.ejs' -exec bash -c 'grep -l -E "</|/>" "$0"' {} \; -exec bash -c 'mv "$0" "${0%.js}.jsx"' {} \;

for files that don't have </ in them, you can run it with /> as well

Thanks!

Bravo!

@parties thanks for the snippet, worked great.

One suggestion, if using git, I changed mv to git mv.

find ./src -type f -name '*.js' -not -name '*.jsx' -not -name '*.ejs' -exec bash -c 'grep -l "</" $0' {} \; -exec bash -c 'git mv "$0" "${0%.js}.jsx"' {} \;

Nice

Updated to also check for self-closing tags (/>), thank you @sean-roberts!

@jsakas I decided not to change it to git mv because it will throw errors if the files aren't under source control, but it's an easy change to make either way. Thanks for calling it out!

Works really well. Good job!

@parties Thanks for the snippet

The command doesn't work if the file or any of its parent folders have names with spaces in them.
/src/pages/Folder With Spaces/Another Folder With Spaces/file.js

To fix this we need to add quotes around $0 for grep: grep -l -E "</|/>" $0 -> grep -l -E "</|/>" "$0"

find ./src -type f -name '*.js' -not -name '*.jsx' -not -name '*.ejs' -exec bash -c 'grep -l -E "</|/>" "$0"' {} \; -exec bash -c 'git mv "$0" "${0%.js}.jsx"' {} \;

Updated to handle spaces, thank you @Dev-Zhao!
