Here strings, three less-than-signs

something i just learned about: the here string, rather than echo pipe to command, it is quicker.

flatmac:~ peter$ a="london 43 smog cafes thames uk"

flatmac:~ peter$ read City Value Bad Good Positive Country <<< $a

flatmac:~ peter$ echo $City

london

flatmac:~ peter$ echo $Good

cafes

flatmac:~ peter$ echo $Country

uk

...or if the delimiter is different, this also works though I need to find out how the IFS assignment and read command work together.

flatmac:record peter$ a="london|43|smog|nice shops|river thames|uk"

flatmac:record peter$ IFS='|' read City Value Bad Good Positive Country <<< "$a"

flatmac:record peter$ echo $Positive

river thames

flatmac:record peter$ echo $City

london
