C: List aliases of current shell (not subshell!) -

-

i'm trying find aliases current shell possesses (in c program). i've tried system("alias"), popen("alias", "r") , execvp("alias", ...), latter of doesn't work @ (because alias shell-specific command) , first 2 of run command in subshell (which sh , not bash) -> there, aliases disabled because defined in ~/.bashrc. executing bash , reading output of alias isn't possible either because bash go alias definitions if in interactive mode.

if do run bash in interactive mode, huge delay time , prompt output want avoid.

basically, want, have similar behaviour time(1). looks current aliases without executing command! (it fork once, is, passed command)

crawling internet no avail.

question: how aliases in current shell? there portability issues? if yes, how avoid them?

regards.

you can't. time built-in , can access aliases stored internally shell instance running. if need work out shell execute, need run or similar.

time isn't doing clever or secret. it's prefix command make shell print out timing information.

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...
