explain bash variable assignement output -

-

can explain me why 

vbb:~ me$ test="zut"; echo $test; echo $test > test2; echo "echo test " $test2

output : 

zut echo test vbb:~ me$

and not

zut echo test zut vbb:~ me$

because echo $test > test2 writes output file named test2.

this set of commands expect:

test="zut"; echo $test; test2=$test; echo "echo test " $test2

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
