BTW I've long wanted to do sth like this:

Assume I have commands my_cat, my_grep, my_sort, my_send, and I want to use them in a pipe

with_prefix my_ | cat file | grep phrase | sort | send | end_with | cat

The last cat would be the system one.

I don't think it's possible with bash?

No, pipes don't work like that. The closest I can think of is something like `(PATH=~/bin; cat file | grep phrase | sort | send) | cat`, where the custom commands don't have a prefix.

You could have a file with functions binding, for example, `grep` to `my_grep`, then `source` that file in a subshell:

   ( source with_my_prefix.sh
   cat file | grep phrase | sort | send | end_with | cat
   )
