Bash script scenarios to read lines from named pipe when using 'read' command in a loop
I've been struggling with this for a few days now and could really use some help. I need help solving I'm trying to figure out I'm trying to read lines from a named pipe (FIFO) in a Bash script, but it seems that the `read` command is not capturing the input as expected. I'm using Bash version 5.1. When I execute the following script, it hangs indefinitely at the `read` command: ```bash #!/bin/bash FIFO=/tmp/myfifo mkfifo $FIFO # Background process that writes to the FIFO ( echo 'line 1' && sleep 1 && echo 'line 2' ) > $FIFO & # Reading from the FIFO while read line; do echo "Read: $line" done < $FIFO ``` I expect the output to display `Read: line 1` followed by `Read: line 2`, but instead, the script hangs after printing the first line. I've tried running it without the `&`, thinking it might be a background process scenario, but that did not help. The FIFO is correctly created, and I can see the outputs when I echo them directly to the terminal, so I suspect it might be related to how the `read` command handles the pipe. Any idea why this happens and how I can fix it? Cheers for any assistance! I've been using Bash for about a year now. Thanks for your help in advance! For context: I'm using Bash on Linux. Any help would be greatly appreciated!
