zig:tldr:ff112

The command zig cc ${filename-c} is likely intended to be used within a build system or a build script.

Here's a breakdown of each part of the command:

• zig cc: This is invoking the Zig compiler (zig cc) to compile the given source code file.
• ${filename-c}: This is a variable substitution or command substitution, depending on the context. The exact meaning depends on the build system or script that interprets the command. The ${filename-c} is replaced with the value of the filename variable or command, with a -c flag appended to it. The -c flag indicates that the compiler should only perform compilation and produce an object file (.o file) without linking it into a final executable.

In simpler terms, this command is likely used to invoke the Zig compiler to compile a source code file (specified by the ${filename} variable) and generate an object file.
