osx - How to install a .pkg from Java Runtime? -

-

i automating installation of .pkg file in mac os x using java , have command bash console:

echo 'control123' | sudo -s installer -pkg /users/george/downloads/mypackage.pkg -target /

i executing command java runtime:

runtime.getruntime().exec("echo 'control123' | sudo -s installer -pkg /users/george/downloads/mypackage.pkg -target /");

but package not installed, if execute command in bash console. works normally.

you shouldn't assume user has root privileges, , it's better idea launch installer user can authorize , update application there. if makes sense, it's possible launch .pkg way, sudo not required:

string userhome = system.getproperty( "user.home" ); string cmdstring = ("open " + userhome + "/downloads/mypackage.pkg");

i'm not sure why need echo 'control123', might need echo separately.

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...
