How to insert blank line using Linux Shell Script together with Python Script?

I'm currently redirecting a Python Script Output to a Log file (log) in Linux

Python Script Example (example.py):

print("output")

Shell script:

python3 example.py >> log

When I check log content (cat log) after running example.py a few times, I get:

output
output
output

So, I'd like to add a blank line before the next "output" entry. The wanted position is:

output

output

output

What should I do in the Shell Script differently in order to achieve so (not editting example.py)?

Thanks

Update:

example.py:

print("output1")
print("output2")

When running a first time python3 example.py | sed 's/$/\n/' >> log, I get:

output1

output2

When running it a second time:

output1

output2

output1

output2

I need to achieve:

output1
output2

output1
output2
Solution

  • You can add an echo after your script finishes executing to add a trailing newline:

    (python3 example.py; echo) >> log
