The not-so-useless “yes” bash command: how to confirm a command in every loop

Question

I wrote a loop to unzip all zip files in a directory.

for f in *zip
do
    unzip $f
done

However, I have to confirm the overwrite at every step

Answer 1

Try using

unzip -o

in your loop

Answer 2

for f in *zip
do
   echo "yes" | unzip $f
done

Answer 3

Wonderful, maybe one of the few cases where yes is still useful

Try with:

for f in *zip
do
    yes | unzip $f
done

Which will work printing "y" at every command.

Or alternatively, you can specify the string provided by yes, like:

for f in *zip
do
    yes A | unzip $f
done

Answer 4

unzip -o $f

per the docs
