cppcheck: Recursively check the current directory, showing progress on the screen and logging error messages to a file.
$ cppcheck . 2> cppcheck.log
try on your machine
This command is used to run the cppcheck tool on the current directory (. represents the current directory).
cppcheck is a static analysis tool for C/C++ code that helps detect potential bugs, code inefficiencies, and style issues in the codebase.
In this command, 2> is a redirection operator that redirects the standard error output of the cppcheck command. By using 2>, any error messages or warnings generated by cppcheck will be redirected to the file cppcheck.log instead of being displayed on the terminal.
So, the command cppcheck . 2> cppcheck.log will analyze the C/C++ code in the current directory using cppcheck, and any error messages or warnings will be saved in the file named cppcheck.log.
