When executing external commands (echo, cat, etc.) from input files with file redirection (>), the output was not properly redirected to the file but instead printed to stdout. crash> cat crashrc echo hi > 1 cat 1 crash> <crashrc crash> echo hi > 1 hi crash> cat 1 crash> When file redirection was used, the code fell through to system() which outputs to stdout instead of using the global fp that was correctly set by setup_redirect().
