New submission from Martin Mokrejs <[EMAIL PROTECTED]>: Although I do appreciate that you try to improve python it is not clear to me from http://docs.python.org/lib/module-subprocess.html:
1. Why the old functions have been deprecated 2. I can pipe together two processes. But how can I use pipe to feed the first process of the two? The example at http://docs.python.org/lib/node535.html is not sufficient. Show how to bind together cat(1) and tr(1). Cat should read from STDIN and pass the same to STDOUT, being read by tr(1). 3. Nowhere is explained what this magic really does: output = p2.communicate()[0] I figured out the result is e.g. a string of '\n' separated lines. What is not clear whether at this very moment the processes get started and whether one can still write on input to them. It seems not, the p1.stdin has to be already populated with data. Thanks. ---------- assignee: georg.brandl components: Documentation messages: 68943 nosy: georg.brandl, mmokrejs severity: normal status: open title: Improve subprocess module usage type: resource usage versions: Python 2.5 _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3235> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
