I'm just saying that for good code structure, especially in printf situaitons where a template bit matches a data argument, doing one at a time give you a virtual array of lines where the template is right by the data and any comment, one field a line, give or take the occasional adjacent series of constants.
At a higher level, put all or minority record types in separate subroutines, so the flow is simple to follow: writeHeader, while ... writeData, writeTrailer.

ESCAPESHELLARG(3) 1 ESCAPESHELLARG(3)
escapeshellarg - Escape a string to be used as a shell argument
SYNOPSIS
string escapeshellarg (string $arg)
DESCRIPTION
escapeshellarg(3) adds single quotes around a string and quotes/escapes any existing single quotes allowing you to pass a string directly
to a shell function and having it be treated as a single safe argument. This function should be used to escape individual arguments to
shell functions coming from user input. The shell functions include exec(3), system(3) and the backtick operator.
On Windows, escapeshellarg(3) instead removes percent signs, replaces double quotes with spaces and adds double quotes around the string.
