A simple and convenient bash script to search something (multiple texts) from C++ header source as mostly located at /usr/include/c++/<version> but for this the script aims at Gcc version 9.0.
Initially this script helps me on studying internal C++'s STL by quickly grep through the source as seen in various header files. Recommended to also have a copy of gcc in case of digging deeper or a certain function is implemented not in header sources.
Put cppgr script into your /usr/local/bin/ directory, or clone this repository then symlink the file there.
- Search for a single text =>
cppgr ostream_iterator - Search for multiple texts => 'cppgr iterator class`
Output would be something like this
