 Hello Dave,
 
 When I try to input gdb command through pipe, I find crash doesn't work
 well, like below.
 
 # echo -ne "gdb help\n gdb help" | ./crash -s
 Undefined command: "".  Try "help".
 gdb: gdb request failed: help
 
 No source file named help.
 gdb: gdb request failed: b help
 
 So I make the patch to clean command, please refer to the patch.

Sure enough -- queued for crash-6.1.0.
Thanks,
