DESCRIPTION

OPTIONS

-d, --defines

Create tag entries for C preprocessor definitions, too. This is the default behavior for -Betags.

-D, --no-defines

Do not create tag entries for C preprocessor definitions. This is the default behavior for -Bctags.

-C, --c++

Treat files with `.c' and `.h' extensions as C++ code, not C code. Files with `.C', `.H', `.cxx', `.hxx', or `.cc' extensions are always assumed to be C++ code.

-t, --typedefs

Record typedefs in C code as tags.

-T, --typedefs-and-c++

Generate tag entries for typedefs, struct, enum, and union tags, and C++ member functions.

-S, --ignore-indentation

Don't rely on indentation as much as we normally do. Currently, this means not to assume that a closing brace in the first column is the final brace of a function or structure definition.

-w, --no-warn

Suppress warning messages about duplicate entries. The etags program does not check for duplicate entries, so this option has no effect on it.

-B, --backward-search

Tag files written in the format expected by vi contain regular expression search instructions; the -B option writes them using the delimiter `?', to search backwards through files. Only ctags accepts this option.

-F, --forward-search

Tag files written in the format expected by vi contain regular expression search instructions; the -F option writes them using the delimiter `/', to search forwards through files. Only ctags accepts this option; it is the default behavior.

-v, --vgrind

Instead of generating a tag file, write index (in vgrind format) to standard output. Only ctags accepts this option.

-x, --cxref

Instead of generating a tag file, write a cross reference (in cxref format) to standard output. Only ctags accepts this option.

-H, --help

Print usage information.

-V, --version

Print the current version of the program.

-i file, --include=file

Include a note in tag file indicating that, when searching for a tag, one should also consult the tags file file after checking the current file. Only etags accepts this option.

-o outfile, --output=outfile

Explicit name of file for tag table; overrides default `TAGS' or `tags'. (But ignored with -v or -x.)

-a, --append

Append to existing tag file. (For vi-format tag files, see also --update.)

-u, --update

Update tag entries for files specified on command line, leaving tag entries for other files in place. Currently, this is implemented by deleting the existing entries for the given files and then rewriting the new entries at the end of the tags file. It is often faster to simply rebuild the entire tag file than to use this. (Implies vi-format tag file.)
