ctags [–aBFwx] [–f tagfile] sourcefile ...
ctags creates a file named tags in the current directory. It summarizes the locations
of various objects in the C source files named on the command line. All files with a
.c or .h suffix are treated as C source files.
For C source code, ctags summarizes function, macro and typedef definitions. See
Appendix H for a description of the format of the tags file.
The tags file is used by ex, more, and vi to support the tag command. The tag
command can be used to edit the file containing a name in the tags file.
For ex and vi, the command is:
: tag name
For more, the command is:
:tname
After these commands are run, the tags file is searched for name. If it is found, the
file associated in the tags file with that name is loaded and the line containing the
name is made the current line.
–a Appends output to the existing tags file rather than overwriting the file.
–B Produces a tags file that searches backward from the current position to
find the pattern matching the tag.
–F Searches for tag patterns in the forward direction. This is the default.
–f Generates a file named tagfile rather than the default tags file.
–w Suppresses warning messages.
–x Produces a report on the standard output. The report gives the definition
name, the line number of where it appears in the file, the name of the file in
which it appears, and the text of that line. ctags arranges this output in
columns and sorts it in order by tag name according to the current locale’s
collation sequence. This option does not produce a tags file.
ctags uses the following localization environment variables:
v LANG
v LC_ALL
v LC_COLLECT
v LC_CTYPE
