(收集)emacs下使用etags

find -name "*.[ch]" -exec etags -a {} \;

#!/bin/sh

trap "rm -f /tmp/$$" 0 1 2 3 15

rm -f ./TAGS

find `pwd`/ -type f -name "*.[chyl]" -print | \
xargs etags --append -o TAGS

find . -type d -print | \
while read DIR; do
  [ "$DIR" != "." ] && ln -f -s `pwd`/TAGS $DIR
done

#!/usr/bin/env python

#使用方法 比如要生成一个TAGS文件包括当前目录下的include和src目录以及子目录下所有的.c .h文件

#命令行： python ezetags -d./include:./src -e.h,.c
