wget script with http get parameters

Question

I have a bash script with the following content:

#!/bin/bash
cap=$1
assist=$2
host=$3

wget "http://$host:8080/MyApp/getNumberFromCap?cap=$cap&assist=$assist" -O - -o /dev/null

but when I run this script it does not make any call to the URL indicated. It seems like it's not resolving the variables put in it, in fact, if I replace the variables with a static content it works like a charm.

Where am I doing wrong?

Just escape the ampersand --> \&. Also, try doing echo "http://..." and see what is really printed. Then, replace with wget. — fedorqui

Works for me.. Are you sure the variables are filled with the correct values? — Jindra Helcl

Escaping the & solved the issue:

wget "http://$host:8080/MyApp/getNumberFromCap?cap=$cap\&assist=$assist" -O - -o /dev/null
                                                       ^

That's it! Thanks! In my case, a $ needed to be escaped.

I had to escape the equal sign too:

wget http://${HOST_IP}/my-bin/myscript?MAILADRESSEN\\="${MAILADRESSEN}"\\&SUBJECT\\="${SUBJECT}"
