Runtime and newgrp

[C. Allen Sher]

Has anyone ran the Unix "newgrp" command from a java Runtime object? I
can't seem to get it to work the way it should.

Issuing *NIX and Linux command-line [i.e. shell] commands can be tricky,
particularly if multiple arguments and file redirection is involved.

Try:

String shell = "/bin/sh",
shellOpts = "/c",
cmd = "/bin/newchrp",
cmdArgs = "groupname > resultfile";

String[] command = { shell, shellOpts, cmd, cmdArgs };
Runtime.getRunt ime().exec(comm and);

or maybe the less fancy:

String[] command =
{"/bin/sh", "-c", "/bin/newgrp groupname > resultfile"};

Runtime.getRunt ime().exec(comm and);

I hope this helps.
