gcc: Show common warnings, debug symbols in output, and optimize without affecting debugging.
$ gcc ${path-to-source-c} -Wall -g -Og -o ${path-to-output_executable}
try on your machine
This is a command written in the Unix shell or a shell script, specifically using the GCC compiler. It is used to compile a C source file into an executable binary file.
Let's break down the command:
gcc
: This is the command used to invoke the GCC compiler.${path-to-source-c}
: This is a placeholder that should be replaced with the actual path to the C source file (e.g.,main.c
). It specifies the source code file that we want to compile.-Wall
: This flag enables a compiler warning called "all" warnings, which means it will display all possible warnings during compilation. This helps in detecting potential issues or problematic code sections.-g
: This flag enables debugging information to be added to the compiled object file. This information is useful when debugging the program using a debugger, as it allows for better tracking of variables and execution flow.-Og
: This flag enables optimization level "g," which is meant for debugging purposes. It applies minimal optimization to the code, ensuring that debugging is easier since the resulting object code closely matches the original source code.-o
: This flag indicates that the following argument is the desired output file name.${path-to-output_executable}
: Similar to the previous placeholder, this specifies the desired name and path of the output executable file. It should be replaced with the actual path and desired name for the resulting binary file (e.g.,myprogram
).
Putting it all together, running this command will use the GCC compiler to compile the C source file specified by ${path-to-source-c}
with additional options for warnings, debugging information, and optimization. The resulting executable file will be saved with the name and path specified by ${path-to-output_executable}
.

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