So, I decided to update a nice old system that does temperature graphing for us. The first issue was the lack of various pms that the perl scripts required. Once that was tackled, I found that the local device graph function was working. But, my netcat grabs were not . So, yes, I could echo and printf my life away and get my values, but in a script, this: my $values = `echo "GET /temp HTTP/1.0\n\n" |nc my.temp.sys 80 `; Did not work. Not at all. So, I thought and thought and did a little digging, and sure enough there’s a registered bug with nc when one wants to pipe data to it. To get those values, here’s what the line’s to look like: my $values = `echo "GET /temp HTTP/1.0\n\n" |nc my.temp.sys 80 -q -1`; So, if you’re using newish ubuntus, 10+, now you know.
