I'd like to have a shell script redirect stdout of a child process in the following manner
- Redirect stdout to a file
- Display the output of the process in real time
I know I could do something like
#!/bin/sh
./child > file
cat file
But that would not display stdout in real time. For instance, if the child was
#!/bin/sh
echo 1
sleep 1
echo 2
The user would see "1" and "2" printed at the same time
