Ok. I explain it once more. Its not about reading the console output of
the command. Its that i want to put a empty file in my subdirectories
so that the name of the file is a message or url or something else.
And if you want an empty file you can do that with
"cat > IAmAnEmptyFileWithOnlyAName"
under linux on the CLI.
'touch filename' is easier when you know the file does not yet exist.
Alternatively, you can do 'cat > filename < /dev/null'
But the problem or advantage of is that you can put some lines in
the text file if you want. And if youre ready youm must
terminate the console/terminal with CTRL+D so that cat knows
that the input is finished.
CTL+D means EOF. In a program you express that by closing the file handle.
fp = open('xyz', 'w')
fp.close()
for creating an empty file, thus
fp = subprocess. .... #get file handle for writing data to the child
fp.close()
for stating that you have no data for the child process.
I have no lines i want to input in the file. So i must only send
and CTRL+D to cat again that it terminates.
Actually a very simple way i thought. But maybe not.
It is simple indeed :)
It is not Python specific, but defined by the underlying OS. That is why you
don't find this information in Python documentation.
