Additionally, you can avoid using "cat" to make the script more efficient. You'll start fewer processes, and complete more quickly. cat is almost never needed unless you actually need to con"cat"enate 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.
