Coud I pass a StringIO object as a "file" argument to a Linux command line?
<p>Some commands on Linux receive a file as an argument. (cat, grep, sed, awk,...)
How can i pass a StringIO object as a "file" argument? (because i don't want to write it to file on disk, then explicitly pass to these commands)
Or i need other kind of "in-memory file" object?</p>

<p>Thanks you!</p>
