etags

The etags command is used to generate tags for C, C++, and Objective-C source files. Tags are markers that can be used to quickly navigate to specific locations in a source file.

For example, to generate tags for all of the C source files in the current directory, you would use the following command:

etags -R *.c

To generate tags for all of the C and C++ source files in the current directory, you would use the following command:

etags -R *.c *.cpp

To list the files that will be tagged, you would use the following command:

etags -l
