Subject: virtual files?
Date: Wed, 20 Apr 2016 01:00:09 +0000 [thread overview]
Message-ID: <8760vdrt5y.fsf@student.uu.se> (raw)
Here is a program I just wrote.
Feel free to comment on any part.
However my specific question is, instead of using the
"result_file" stuff, is there support for
I suppose "virtual files" or basically a data structure
that can be used transparently as a file, or with but
small adjustments?
TIA.

wget -q $link -O $result_file
echo -n \$
grep \"answer\" $result_file | cut -d \$ -f 2 | cut -d \< -f 1
rm $result_file
}
