Unix shell handles variables abysmally.  You need to help it a lot to
do the right thing.  *Always* quote variables, else if they're empty
they tend to blow up on you.

  ---------------------------------------------
#!/bin/bash
#
# usage:    gbg.sh "http://url.with/an&ampersand";
#
url="$1"; shift
echo "$url" # >>tmp.txt

exit 0

# Output:

(0) infidel /home/keeling_ sh/gbg.sh "http://url.with/an&ampersand";
http://url.with/an&ampersand
  ---------------------------------------------

HTH.  :-)  Oh, you could do ${1} and ${url} instead, but even they
need to be quoted.
