Shell Development asked two hundred also fail 1, I would like to achieve two of the shell script running through mutual transmission of values to variables (not achieved through written documents), how to write? 2, a certain order to redirect the output to a document, but the result of this order could export as much, which may result in decreased performance or the lack of disk space, and only really useful output in the last line, we would like to ask about how to handle the squatters? (Tail increases with the order form may well be insufficient memory ah) [ Closed window ]
