9.1 Help for command-line options

To obtain a brief reminder of various command-line options, GCC provides a help option which displays a summary of the top-level GCC command-line options:

$ gcc --help

To display a complete list of options for gcc and its associated programs, such as the GNU Linker and GNU Assembler, use the help option above with the verbose (-v) option:

$ gcc -v --help

The complete list of options produced by this command is extremely long--you may wish to page through it using the more command, or redirect the output to a file for reference:

$ gcc -v --help 2>&1 | more
