Question

I am trying to find {AUTH-KEYS-SALTS} in the file wp-config.php and replace it with the contents of the bash variable keysalts.

keysalts=`curl -sS https://api.wordpress.org/secret-key/1.1/salt/`
sed -i "s/{AUTH-KEYS-SALTS}/$keysalts/g" wp-config.php

The following almost works, except that keysalts has a bunch of special characters such as $`;'” and sed is getting confused. Basically, how do I escape everything and just replace {AUTH-KEYS-SALTS} with $keysalts?

Thanks.

Other way could be using perl:

perl -i -pe '
  BEGIN { 
    $keysalts = qx(curl -sS https://api.wordpress.org/secret-key/1.1/salt) 
  } 
  s/{AUTH-KEYS-SALTS}/$keysalts/g
' wp-config.php
