The wise coder will never pipe grep into awk
For unneeded processes cause neighbours to talk.
The wise coder will never type cat file | foo
Unless they want a UUoCA too.
The wise coder will never discard output from backticks
As that displays ignorance of better tactics.
The wise coder won't shell out to grep, awk or sed
Since no JAPH would be seen doing that, dead.
