Question

Bash script with cat and $1

Hello, I am writing a script which, among other things, generates Nginx configuration. Unfortunately, I ran into a problem. In Nginx config, I need to type $1. I use the following method for this:

cat > /etc/nginx/sites-available/website <<EOL
...
rewrite ^/api/?(.*)$ /web/api.php?url=$1 last;
...
EOL

This makes the output file look like this:

...
rewrite ^/api/?(.*)$ /web/api.php?url= last;
...

How do I make cat not interpret $1 as a parameter?

Hello,

What you could do is just use a backtick to escape the dollar sign:

cat > /etc/nginx/sites-available/website <<EOL
...
rewrite ^/api/?(.*)$ /web/api.php?url=\$1 last;
...
EOL

Hope that this helps Regards, Bobby
