Options Options specifying input and action: --file=filename Checks individual files for security features compiled into the executable --dir=directory Recursively checks all executable files in the directory for security features compiled into the executables --listfile=listfile Check all files specified in a newline-separeted text file for security features compiled into the executable --proc=pid Checks the security features of a running process by name --proc-all Checks the security features of all running processes --proc-libs Checks the security features of the all libraries of a running process ID --kernel[=config] Checks the security features of the running kernel or a specified kernel config --fortify-file=filename Checks for the use of fortifiable and fortified library functions in a file --fortify-proc=pid Checks for the use of fortifiable and fortified library functions in a running process Options modifying behavior: --debug Enable debug-level output. --extended Check for additional security features (e.g. Clang CFI, SafeStack) --libcfile=path Specify the libc file path or a search path --output=(cli|csv|xml|json), or --format=(cli|csv|xml|json) Output the results in different formats for ingestion to other applications. --trace Enable bash tracing (set -x). Miscellaneous options: --debug_report Generate a system report and exit. -h or --help Displays the help text and exit --update or --upgrade Checks source for a signed update and updates the application if available and exit --version Shows the current version of the running software and exit DIAGNOSTICS The following diagnostics may be issued on stderr: Permission Denied.
