sed command not working in mac

Question

Following sed command is not working on my lion mac.

find . -type f -exec sed -i \'s/user_dashboard/user/g\' {} \\;

I am getting this error

Answer 1

-i probably has a different meaning (not "in-place") in your version of sed. Try using gsed if available or replacing -i with -e and using a temporary file (and a mv afterwards) to emulate it.

Answer 2

The OSX version of sed is not the same as those found in most Linux systems.

It extends the -i option to give you the opportunity save a file with a different extension, but requires input for that extension.

If you just want to overwrite the file in place, you need to use sed -i "" ...sedCmd.... fileName to rename your file in-place.

Per @JamesMcMahon 's comment, see here for the full doc for OSX/BSD sed.

I hope this helps.

Answer 3

replacing text inside a text file on the fly with sed on mac is possible.

the command is just a little different.

with: -i , you specify an extension where sed will save the original file prior to the sed operation.

run the command as:

$ sed -i _bakup -E 's/THESTRING/THEGRANDSTRING' /tmp/jestinkt.txt
