Additionally, you can avoid using "cat" to make the script more

multiple files.

I sometimes like to use cat purely for stylistic reasons :

cat file.txt |\
   sed -e s?"foo"?"bar"?g |\
   sed -e s?"dirty"?"clean?" |\
   > file2.txt

It lets me line up my sed expressions.

But yes, that is wasting a process for easier visualization. Worth it to me.
