How to include an '&' character in a bash curl statement
Putting the entire URL inside double quotes should take care of your problem.
curl "http://www.example.com?m=method&args=1"
Are you using the & as a delimiter for a GET URL? Or is in a piece of data?
If it is in data you must encode it to an HTML character, if not, surround with quotes.
The encoding for & should become %26 in the URL.
curl "http://www.example.com?m=this%26that
Putting single quotes around the & symbol seems to work. That is, using a URL like http://www.example.com/page.asp?arg1=${i}'&'arg2=${j} with curl returns the requested webpage.
