ccache

C/C++ compiler cache. Note: packages usually provide symlinks for compilers in /usr/lib/ccache/bin. Prepend this directory to $PATH to automatically use ccache for them. More information: https://ccache.dev/manual/latest.html.

• Show current cache statistics:

ccache --show-stats

• Clear all cache:

ccache --clear

• Reset (zero) statistics (but not cache itself):

ccache --zero-stats

• Compile C code and cache compiled output (to use ccache on all gcc invocations, see the note above):

ccache gcc path/to/file.c
