[ExM Users] app fails

[Ketan Maheshwari]

Hi,

The following T script with app def fails for me:

import files;
import io;
import string;

app (file o) cmd (string acmd, string arg) {
  "/bin/bash -c" acmd arg @stdout=o
}

main {
file output<sprintf("s.txt")> = cmd("echo", "hello");
}


CAUGHT ERROR:
external command failed: /bin/bash -c echo hello
    while executing
"error $msg"
    (procedure "turbine_error" line 6)
    invoked from within
"turbine_error "external command failed: $cmd $args""
    (procedure "turbine::exec_external" line 16)
    invoked from within
"turbine::exec_external "/bin/bash -c" [ dict create "stdout"
${v:__filename:o} ] ${v:acmd} ${v:arg}"
    (procedure "cmd-app-leaf0" line 17)
    invoked from within
"cmd-app-leaf0 0 {7.0} 1 {1} {4} {file 7 is_mapped 1}"

    (procedure "worker" line 28)
    invoked from within

    (procedure "enter_mode_unchecked" line 5)
    invoked from within
"enter_mode_unchecked $rules $startup_cmd"
    (procedure "enter_mode" line 10)
    invoked from within
"enter_mode $rules $startup_cmd "
CALLING adlb::abort
ADLB_Abort(1)
MPI_Abort(1)
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 1


I want to run an arbitrary command with arbitrary args via /bin/bash or
/bin/sh.

Any suggestions?

Thanks,
Ketan
