It can be invoked with: ./print.awk <filename> The -f tells awk that the argument that follows is the file to read the AWK program from, which is the same flag that is used in sed. Since they are often used for one-liners, both these programs default to executing a program given as a command-line argument, rather than a separate file.
The search_expr could contain a range as in F:/hello/,/world/ to find all lines that start with the string "hello" and contain the string "world" too. TEX provided standard line-based file editing commands: P: print current line; F: move forward through the current file line by line; B: move backward through the current file line by line
A few fields can contain comments (i.e. in User-Agent, Server, Via fields), which can be ignored by software. [8] Many field values may contain a quality (q) key-value pair separated by equals sign, specifying a weight to use in content negotiation. [9]

sending the information about the content-transfer encoding and the Unicode transform used so that the message can be correctly displayed by the recipient (see Mojibake). If the sender's or recipient's email address contains non-ASCII characters, sending of a message requires also encoding of these to a format that can be understood by mail ...
For some C compilers, an extra format specifier results in consuming a value even though there isn't one. This can allow the format string attack. Generally, for C, arguments are passed on the stack. If too few arguments are passed, then printf can read past the end of the stack frame, thus allowing an attacker to read the stack.
The interpretation of the control key with non-ASCII ("foreign") keys also varies between systems. Control characters are often rendered into a printable form known as caret notation by printing a caret (^) and then the ASCII character that has a value of the control character plus 64. Control characters generated using letter keys are thus ...
