New line in git hook

I have a git hook which calls a php file. The php file will produce an output (after running some Unit Tests). Te hook file is a sh file. The output from php file is echoed to the terminal, but \n is stripped, and everything is on a single line. Any ideas what I have to do to have new lines?

Thanks

The solution is to use printf '%s\n' "$output"

The key elements are %s which interprets the output as string, and the double quotes "" which interpret the entire string as a single input. If you don't add the double quotes then every space is replaced by \n, so you would end up with a single word per line. Obviously, the actual string to display is stored in $output.

You can try and, in your sh script,

  • assign the output of the php script to a variable avar;

  • echo that variable with:

    echo -e "${avar}"

That should keep the newlines, as mentioned in "echo multiple lines into a file".

The same link mentions printf as well.

printf '%s\n' "${avar}"
