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 example prints every line (implicit) and quits after the fifth. Equivalently, awk may be used to print the first five lines in a file: awk 'NR < 6' filename. However, neither sed nor awk were available in early versions of BSD, which were based on Version 6 Unix, and included head. [1]
The AWK Programming Language [1] is a well-known 1988 book written by Alfred V. Aho, Brian W. Kernighan, and Peter J. Weinberger and published by Addison-Wesley, often referred to as the gray book. [2] The book describes the AWK programming language and is the de facto standard for the language, written by its inventors. W.

PC-based C cross-compilers for some of the TI and HP machines used with tools that convert between C and Perl, Rexx, AWK, and shell scripts to Perl, Modern Pascal, VBScript to and from Perl make it possible to write a program in a glue language for eventual implementation (as a compiled program) on the calculator.

xargs (short for "extended arguments") [1] is a command on Unix and most Unix-like operating systems used to build and execute commands from standard input.It converts input from standard input into arguments to a command.
Many languages have a syntax specifically intended for strings with multiple lines. In some of these languages, this syntax is a here document or "heredoc": A token representing the string is put in the middle of a line of code, but the code continues after the starting token and the string's content doesn't appear until the next line. In other ...
all text after the first space is treated as a single argument, that is, python3 -c will be passed as one argument to /usr/bin/env, rather than two arguments. Such systems include Linux [18] [19] and Cygwin. Another approach is the use of a wrapper.
