Suppose I have a binary called
If I want to redirect the output of
foo to some other process
bar, I could write
./foo | bar.
On the other hand, if I wanted to
time foo, and redirect the output of
time I could write,
time (./foo) | bar.
My question is, how can I stick the output of
time to the end of the output of
foo and pipe it through the same pipe?
The following solution is not what I am looking for, because it starts two separate instances of the process
bar, while I want a single shared pipe, to a single instance of
time (./foo | bar) | bar
For anyone who is curious, the reason for not wanting to start two instances of
bar is because
bar can be a network client and I want the timing information to be sent to the server as part of the same
http POST message as the process output.
