bash - How to use environment modules in a ssh command line? -

-

the environment modules package used dynamic modification of user's environment (debian package environment-modules).

i use module directly ssh command line. purpose able execute commands on different nodes bash script executed on front node. don't want explicitly update path , ld_library_path environment variables each different node configuration.

when directly connect node , call module node, working:

jyvet> ssh mynode jyvet@mynode> module load gcc-6.0 jyvet@mynode> gcc --version gcc (gcc) 6.0.1

but following approach fails:

jyvet> ssh mynode "module load gcc-6.0; gcc --version" command not found: module gcc-4.8 (debian 4.8.4-1) 4.8.4

module initialized /etc/profile.d/modules.sh called /etc/profile (which sets environment variables @ startup of shell).

the ssh command execution shell non-interactive shell , neither call /etc/profile, nor read config files.

here solution:

jyvet> ssh mynode "source /etc/profile; module load gcc-6.0; gcc --version" gcc (gcc) 6.0.1

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...
