The ctstat -userinfo function has been modified to output additional information. As of V11.5, the output of ctstat -userinfo is as follows:
status lastrequest trntime mem fils time uid/tid/nodename commprotocol
Because the column labeled uid/tid/nodename is not fixed in size, the space between nodename and commprotocol is a tab character. Even if the output is not properly aligned, the parsing will be easy by looking for a '\t' (tab).
