meaning of $(<filename) in bash

vincix · 02-22-2018, 08:58 AM

In this link (https://stackoverflow.com/questions/...sing-last-line) I saw the following:

Code:

$ for line in $(<y); do echo $line; done

As far as I can tell, 'y' is the name of a file. What is the "<" supposed to mean?

thanks

Ok, I think I get it. It's simply inputting the content of the file name called "y"

I think that is a correct interpretation, however not one I've ever used.

In the future, would suggest you post questions about scripting or programming in the Programming forum. There's a much greater concentration of expertise in that forum versus in Newbie.

Ok, thanks for the tip. I tended to use the newbie forum because it seems to be a noobish question, but I get your point.
