How do I include special characters like @ and & in the cURL POST data? I'm trying to pass a name and password like:
curl -d name=john passwd=@31&3*J This would cause problems as @ is used for loading files and & for specifying more than one key/value. Is there some way I can escape these characters? \@ and \& don't seem to work.

cURL > 7.18.0 has an option --data-urlencode which solves this problem. Using this, I can simply send a POST request as
curl -d name=john --data-urlencode passwd=@31&3*J Summarizing the comments, in case of mixed "good" and "bad" data and exclamation marks inside we can use on Windows:
curl -d "grant_type=client_credentials&client_id=super-client&acr_values=tenant:TNT123" --data-urlencode "client_secret=XxYyZ21D8E&%fhB6kq^mXQDovSZ%Q*!ipINme" How about using the entity codes...
@ = %40
& = %26
So, you would have:
curl -d 'name=john&passwd=%4031%263*J'
Double quote (" ") the entire URL .It works.
curl "" Just found another solutions worked for me. You can use '\' sign before your one special.
passwd=\@31\&3*J Try this:
export CURLNAME="john:@31&3*J" curl -d -u "${CURLNAME}" If password has the special characters in it, just round the password with the single quote it will work.
curl -u username:'this|!Pa&*12' --request POST I did this
~]$ export A=g ~]$ export B=! ~]$ export C=nger curl
