Multi-command pipelines has an invalid test

Platform Bug Reports

Hello,

there is a problem with the test “Running tests for Stage #XK3 (Pipelines - Multi-command pipelines)”

You create a file with 5 words and your head command gets them all. I had a bug in my code so multiple pipes were not processed correctly. Instead only the first command and the last command was piped together.

This test passed even with my bug.

You should check with head -n 3 for instance. This would have failed in my case.

[tester::#XK3] Running tests for Stage #XK3 (Pipelines - Multi-command pipelines)
[tester::#XK3] [setup] export PATH=/tmp/orange/mango/blueberry:$PATH
[tester::#XK3] [setup] echo -e “strawberry\ngrape\napple\nraspberry\nbanana” > “/tmp/pig/file-16”
[tester::#XK3] Running ./your_program.sh
[your-program] $ cat /tmp/pig/file-16 | head -n 5 | wc
[your-program] 5 5 40
[tester::#XK3] ✓ Received expected output

I recreated the file locally and tested with a real shell:
[22:37:46]-[gillouche@macbook]-[gillouche/.ssh] $ cat /tmp/file-16| head -n 5 | wc
5 5 40
[22:38:02]-[gillouche@macbook]-[gillouche/.ssh] $ cat /tmp/file-16| head -n 3 | wc
3 3 23

[22:40:30]-[gillouche@macbook]-[gillouche/.ssh] $ cat /tmp/file-16 | wc
5 5 40
