Hi,
Within a function, I'd like to print some input to the terminal and at the same time
store it in a fifo fostore some input in a fifo, but am getting mixed results. In this
example, I thought "hello" would be output twice:
$>cmd_print () { mkfifo zout ; (tee zout &); cat zout ; rm zout; }
$>printf 'hello\n' | cmd_print
This outputs "hello" twice:
$>cmd_print () { mkfifo zout ; (cat - | tee zout &); cat zout ; rm zout; }
$>printf 'hello\n' | cmd_print
hello
hello
but this doesn't output anything:
$>cmd_print () { mkfifo zout ; (cat - | tee zout &) ; rm zout; }
$>cmd_print <<EOF
$> date
$> EOF
My real goal is to feed data to a function and then source it:
$> cmd_print () { mkfifo zout ; (cat - > zout ) & ; source zout ; rm zout; }
$> cmd_print <<EOF
$> date
$> EOF
$>
Could anyone please provide a few pointers on how to accomplish this, and
perhaps explain the results from the above examples?
