How to group bash command into one function?

Here is what I am trying to achieve. I want to run a sequence of commands on that file, so for example

ls * | xargs (cat - | calculateforfile)

I want to run (cat | calculateforthisfile) on each of the file separately. So basically, how to group a list of commands as if it is one single function?

If you're looking for xargs solution for this (for example find command)

find . -name "*.txt" | xargs -I % cat %

This will cat all the files found under current directory that end in .txt The -I option is the key there

No need to use xargs. Just use a loop. You also don't need to use cat. Just redirect its input with the file.

for A in *; do
    calculateforfile < "$A"
done

As a single line:

for A in *; do calculateforfile < "$A"; done
