Trying to use Linux bash script to write to a file but unable to write the below line because of the extra " and ' symbols in the line. Is there a better way to write a file with linux bash script or a way that will work?
echo "add_header Content-Security-Policy "default-src 'self' https://*.jsdelivr.n$ >> $file
I'm a noob to bash scripting and appreciate the help.
There are several ways to do this. A heredoc is a good choice:
cat >> $file << \EOF
add_header Content-Security-Policy "default-src 'self' https://*.jsdelivr.n$
EOF
This simply takes everything until the EOF verbatim as input to cat, and writes it to the file. (It's not clear to me if you want a double quote before add_header; if so, prepend it.) Another reasonable alternative is to escape double quotes in a double quoted string:
echo "add_header Content-Security-Policy \"default-src 'self' https://*.jsdelivr.n$" >> $file
