 |
|
Hi!
I have a question for the shell-programming guru's out there. Assume i have the following script:
| Code: |
read test; echo $test
|
Now i want another script to send the input to the script above. In my opinion this should work:
| Code: |
echo "bla" > /proc/<PID of shell above>/fd/0
|
The result of this is, that bla is written to the stdin of the first command (i see it on the commandline so i know that it's the correct file-descriptor) but the linefeed is somehow not recognized and thus the script never terminates.
Now my question is: Is it possible to do this or do i have to come up with something else?
