linux - Installing RVM with a specific bash command format using `-s` -

-

i'm trying install rvm via bash. according installation guide on rvm.io, command is:

\curl -ssl https://get.rvm.io | bash -s stable --auto-dotfiles

i'm, however, compelled download script , run separately. so, bash command attempt execute downloaded file (let's call rvm-installer).

how can execute rvm-installer using format below:

/bin/bash -c './rvm-installer 2>&1'

obviously, above command incorrect. i'm thinking should more this:

/bin/bash -s stable --auto-dotfiles './rvm-installer 2>&1'

i know above command sets positional parameters in correct order because of this:

$ printf "%s\n" "$@" stable --auto-dotfiles ./rvm-installer 2>&1

and this:

$ echo "$shlvl" 2

but i'm confident rvm-installer not running because replaced contents following, test once command above run, see no output:

#!/usr/bin/env bash  gimme syntax error echo "$1" echo "foo bar" exit 1

how can run rvm-installer using -s within bash command format need use? there way around using -s?

-s bash argument not rvm-installer argument.

the other arguments rvm-installer arguments.

so pass rvm-installer yourself.

./rvm-installer stable --auto-dotfiles

using the, entirely pointless, explicit call bash this

/bin/bash -c './rvm-installer stable --auto-dotfiles 2>&1'

though meaningfully well

/bin/bash rvm-installer stable --auto-dotfiles 2>&1

c# - Where does the .ToList() go in LINQ query result -

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
