# form.awk is an awk script that requires access to 2 files: The # first file is called "form.letter." This file contains the # format for a form letter. The awk script uses another file, # "data.form," as its input file. This file contains the # information that will be substituted into the form letters in # the place of the numbers preceded by pound signs. Today's date # is substituted in the place of "@date" in "form.letter." BEGIN{ FS=":"; n=1 while(getline < "form.letter" > 0) form[n++] = $0 # Store lines from form.letter in an array "date" | getline d; split(d, today, " ") # Output of date is Fri Mar 2 14:35:50 PST 2004 thisday=today[2]". "today[3]", "today[6] } { for( i = 1; i < n; i++ ){ temp=form[i] for ( j = 1; j gsub("@date", thisday, temp) gsub("#" j, $j , temp ) } print temp } }
