This command uses the debugger to attach to a running process, and reassign a filehandle to a file. The two commands executed in gdb are p close(1) which closes STDOUT and p creat("/tmp/filename",0600) which creates a file and opens it for output. Since file handles are assigned sequentially, this command opens the file in place of STDOUT and once the process continues, new output to STDOUT will instead be written to our capture file. Show Sample Output
8yes 'Y'|gdb -ex 'p close(1)' -ex 'p creat("/tmp/output.txt",0600)' -ex 'q' -p pid -

I doubt this works with other than bash, but then again, I havent tried. The 'yes' utility is very simple, it outputs a hell of a lot of 'y's to standard input. The '!!' command means 'the last command'. So this one-lines inputs a lot of y's into the last command, aggressively agreeing to everything. For instance, when doing apt-get.
1yes | !! -
