This week: I have a simple shell function, “fields”, that generates a numbered list of the fields in a data table. With those field numbers I can then use AWK and the cut command efficiently on the command line. As an alternative I use a “fieldlist” function that puts the numbered list on my desktop like a Post-it note.
