I think you want to modify the socket stream to translate \n (line feed) to CRLF (Carriage return & line feed). Doing info socat produces detailed information which includes this modifier: crnl Converts the default line termination character NL (‘\n’, 0x0a) to/from CRNL (“\r\n”, 0x0d0a) when writing/reading on this chan- nel (example).

As pastebin.com closed their public api, I was looking for alternatives. Sprunge is great. Usage: <command> | curl -F ‘sprunge=<-‘ http://sprunge.us or, as I use it: alias paste=”curl -F ‘sprunge=<-‘ http://sprunge.us” <command> | paste
On the first case you call the script with testFunct param2. Hence, it understands param2 as the first parameter. It is always recommendable to pass parameters within quotes to avoid this (and to be honest, for me it is cleaner this way).
