how to use in bash variables and quotes
I have some troubles with variables and quotes...

I want:

if $URL is empty (no user input) go to http://www.localhost/index.php/ else add this string (search) "?s=+$URL"

EXAMPLE:
No user input
string= http://www.localhost/index.php/

User input = "unix"
string= http://www.localhost/index.php/s=+unix

No luck with:


Code:
#!/bin/bash

read URL
#if [ $? = 1 ];
#then exit
#fi
LINK=$("http://www.localhost/index.php/")
SEARCH=$("?s=+$URL")
if [ $var == "" ]
then
LINK1=$(lynx -dump $LINK)
else
LINK1=$(lynx -dump $LINK$SEARCH)
fi
# exec command:
exec $LINK1


Output:


line 8: ?s=+unix: command not found
line 9: [: ==: unary operator expected
line 16: Lynx: command not found
