It doesn't fix it
Another shot:
Code:
awk '(NR==1&&/^"http:/||NR>1&&/^http:/)&&$0=RS$0RS' RS=\"
Code:
awk '$0~"^"(NR==1?"\"":x "http:")&&$0=RS$0RS' RS=\"
Quote:
Then why is using /^http:/ skipping http://zzz ?

up till now I thought awk was working on a line basis but it appears to be working on a record basis, it is just that the default record separator coincides with a newline
Of course, there is even more (even Perl does not have this one), in GNU AWK the RS could be a regexp (see also the powerful RT built-in variable),

WebCommon::urlEncode - URL encode a string SYNOPSIS
String urlEncode( String x ) ARGUMENTS
x The string to encode DESCRIPTION
URL encode a string. You should use this to encode reserved characters in URLs that you wish to be passed literally. // trying to pass "http://www.example.com" as a parameter url = "http://localhost/test.cgi?url="; url += urlEncode("http://www.example.com"); // url = http://localhost/test.cgi?url=http%3A%2F%2Fwww.example.com Note that in the example above, encoding the whole URL would be incorrect - that would create a relative URL beginning "http://".
