I want to send the output of a pipe and stdin to a pipe in bash. I.e: <pre class="prettyprint"><code>gen_input | cat - | parse_input_and_stdin </code></pre> would send the output of <code>gen_input</code> to <code>parse_input_and_stdin</code> and then leave stdin open for more interactive input.

Close. <pre class="prettyprint"><code>{ gen_input ; cat ; } | parse_input_and_stdin </code></pre>

How to concatenate stdin in to a pipe?

I want to send the output of a pipe and stdin to a pipe in bash.

I.e:

gen_input | cat - | parse_input_and_stdin

would send the output of gen_input to parse_input_and_stdin and then leave stdin open for more interactive input.
