Calling Echo inside a function pre-pends echo string to return value in Powershell
Category : Programming Languages

Hey guys, I'm a Powershell noob and seem to keep getting caught on little weird behaviors like this. Here is some test code:


function EchoReturnTest(){
echo "afdsfadsf"
return "blah"
}
$variable = EchoReturnTest
echo ("var: " + $variable)

Running this script generates this as output: "var: afdsfadsf blah"

Is it better to echo javascript in raw format with php, or echo a script include that has been minified and gzipped?

In PHP, why wasn't echo implemented as a function? (not echo vs. printf)
Category : PHP

I already knew that echo is a language construct.

UPDATE: By the way, was printf implemen

creating an echo timestamp / cannot use pipe in echo string
Category : Network & Servers

I would like to use timestamps for logging outputs in a scriptfile.


On the console


date +%Y%m%d_%H%M%S_%N
