Is there any way to write a redirection "Redirect the fd whose number is in $FOO to file /foo/bar?" OK, you can write 'bash -c "..."' and assemble a command string however you want. But is there a direct way to write it? The "{var}>..." mechanism *assigns* to $var, rather than taking its existing value.
If you want an extra round of word expansion, use eval. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRU chet@case.edu http://tiswww.cwru.edu/~chet/
