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:

replace file123.txt? [y]es, [n]o, [A]ll, [N]one, [r]ename: A

How can I rewrite a loop to send at every cycle the same command?

Answer 1

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
