Hi.

Extensive use in software. See Dollar sign - Wikipedia

Also in development situations, build utility make is often used, and some variables of interest there are:
Code:
Automatic Variables that make will set after a rule match:

   $@  Filename representing the target
   $%  Filename element of archive member specification
   $<  Filename of the first prerequisite
   $?  Names of all prerequisites newer than target, space separated
   $^  Names of all prerequisites, duplicates removed, spaced
   $+  Same as $^, but with duplicates removed, spaced
   $*  Stem of the target - typically file without suffix

   from: GNU make, 3rd, O'Reilly, pages 16-17

As is often the case, fact-based questions are often best answered by searching, Google and Wikipedia are your friends.

Best wishes ... cheers, drl

fcstrcopyfilename

FcStrCopyFilename(3)													      FcStrCopyFilename(3)

NAME

       FcStrCopyFilename - create a complete path from a filename

SYNOPSIS

       cc [ flag... ] file... -lfontconfig [ library... ]

       #include <fontconfig.h>

       FcChar8 * FcStrCopyFilename (const FcChar8 *s);

DESCRIPTION

       FcStrCopyFilename  constructs  an  absolute pathname from s. It converts any leading '~' characters in to the value of the HOME environment
       variable, and any relative paths are converted to absolute paths using the current working directory. Sequences of '/' characters are  con-
       verted  to a single '/', and names containing the current directory '.' or parent directory '..' are correctly reconstructed.  Returns NULL
       if '~' is the leading character and HOME is unset or disabled (see FcConfigEnableHome).

VERSION

       Fontconfig version 2.5.0
