clang: Compile source code without linking.
$ clang -c ${input_source-c}
try on your machine
The command clang -c ${input_source-c}
is a command to compile C source code using the Clang compiler.
Here is a breakdown of the command:
clang
is the command to invoke the Clang compiler.-c
is an option to tell Clang to generate object code instead of an executable. It stands for "compile only".${input_source-c}
is a form of variable substitution. It is used to retrieve the value of the variableinput_source
and substitute it in place, but with a fallback value of "c" if the variable is not set. The exact way this substitution works depends on the shell or script in which this command is used.
In essence, this command is used to compile a C source file into object code using the Clang compiler. The input source file is specified by the value of the input_source
variable if it is set, otherwise, the filename will be "c".

never run a command you are not sure if it is safe.
