[julia-users] Spawning (or running) an external program with given environment variables.
In Bash I can do something like this $ echo $RANDOM_VAR $ RANDOM_VAR='heya' env RANDOM_VAR='heya' OTHER_ENV_VAR=whatever_it_was_before ... $ echo $RANDOM_VAR $ In Julia, however, julia run(`env`) OTHER_ENV_VAR=whatever_it_was_before ... julia run(`RANDOM_VAR='heya' env`) ERROR: could not spawn `RANDOM_VAR=heya env`: no such file or directory (ENOENT) in _jl_spawn at process.jl:217 in spawn at /usr/local/Cellar/julia/0.3.3/lib/julia/sys.dylib (repeats 2 times) in run at /usr/local/Cellar/julia/0.3.3/lib/julia/sys.dylib julia Is there a way to emulate this behaviour in Julia?

Also: julia ENV[FOO] = BAR BAR julia run(`env` | `grep FOO`) FOO=BAR On Wed, Dec 31, 2014 at 3:35 PM, Sean Marshallsay srm.1...@gmail.com wrote: Awesome, thank you!

Re: [julia-users] Spawning (or running) an external program with given environment variables.
Thanks Stefan but I ideally wanted something that would leave ENV intact (which setenv does). On an unrelated note, how on earth do you find the time to answer all these questions so quickly? However you do it, thanks for being so dedicated.
