Topic: ✔ run(`cat file.txt >> out.txt`) ?

Leandro Martínez (Feb 16 2024 at 14:45):

How can I run the equivalent of a cat for appending a file to another, from within Julia? The run(pipeline(cat file.txt, stdout="out.txt")) option overwrites the output file.

shell> cat foo.txt
hi

julia> open("foo.txt", "a") do io
         run(pipeline(`ls -la`, stdout=io))
       end
Process(`ls -la`, ProcessExited(0))

shell> cat foo.txt
hi
