== execlineb ==

[https://skarnet.org/software/execline/execlineb.html execlineb] is the interpreter for execline scripts. It reads a file, produces a command-line, and executes into that command line. <code>execlineb</code> manages the environment of the command that it executes and ~~optionaly~~ substitutes the arguments a script receives into the command-line. <code>execlineb</code> also handles the quoting of strings using <code>""</code> and blocks using <code>{}</code>. Blocks are described later in this article.

then the expression

args: lib.escapeShellArgs (quoteExecline [ "pipeline" "-w" [ (lib.getExe pkgs.cowsay) ] ] ++ args)

args: lib.escapeShellArgs (quoteExecline [ "pipeline" "-w" [ (lib.getExe pkgs.cowsay) "-r" ] ] ++ args)

</syntaxHighlight>

would produce the command-line executed by <code>execlineb</code> in the previous "wrap-cowsay" example when given the same arguments.
