On my local system, it appears that the configuration for awk has somehow been changed.
Running the following command:
echo "Hi there" | awk '{print $2}'
On my machine this prints:
Hi there
And on my development server it prints:
there
I am sure that at some point my local machine would behave the same as my server - i.e. it should print only the second word.
How do I reset the awk field separator back to its default (which according to this page is a sequence of spaces)?

Yeah, no... there's... there's no way it could possibly have the former output. Unless it's not awk. – Ignacio Vazquez-Abrams – 2011-05-12T16:06:56.313
Apologies. I was actually running this on my local system: echo "Hi there" | awk "{print $2}" Hadn't realised that double quotes and single quotes were used differently. – Alex Spurling – 2011-05-12T16:14:07.337
Indeed. Double quotes allow variable substitution, which would cause
$2to collapse to nothing, printing the whole line. – Ignacio Vazquez-Abrams – 2011-05-12T16:15:08.5231You might have done this:
echo Hi there | awk '{print $2}'– ceving – 2011-05-12T16:16:34.060/ Ignacio: I hope one of you will post an answer regarding double quotes - then Alex can mark it as accepted. – RedGrittyBrick – 2011-05-12T19:31:05.703
