Undefined parameter values are tricky: if the first positional parameter was not defined in the template call, then {{{1}}} will evaluate to the literal string "{{{1}}}" (i.e., the 7-character string containing three sets of curly braces around the number 1), which is a true value.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
Jawk is a project to implement AWK in Java, hosted on SourceForge. [20] Extensions to the language are added to provide access to Java features within AWK scripts (i.e., Java threads, sockets, collections, etc.). xgawk is a fork of gawk [21] that extends gawk with dynamically loadable libraries. The XMLgawk extension was integrated into the ...

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.
Currently the article claims mawk is a very fast AWK implementation, but I have a counter example: match execution time grows exponentially on certain regular expressions, when you increase input length For some reason mawk is the default awk interpreter in most Ubuntu Linux variants, but the version of mawk, that is inherited from Debian Linux ...
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.
