GNU Parallel with sed wrong arguement as file

Question

I want to change all occurrences of <ga/ to <. With xargs, this works fine:

ls | xargs sed -i 's/<ga\//</g'

GNU Parallel says that it's a direct replacement for xargs, but doing

ls | parallel sed -i 's/<ga\//</g'

results in

/bin/bash: ga//: No such file or directory

for each file in the directory. I'm sure that I'm just forgetting a {} or \; somewhere, but the answer still alludes me.

Answer 1

ls | parallel -q sed -i 's/<ga\//</g'
