yum install ctags

Package ctags-5.8-13.el7.x86_64 already installed and latest version

创建 /home/mzh/pptp-master/tags.sh

#!/usr/bin/sh

WORKDIR=/home/mzh/pptp-master

find ${WORKDIR} -name "*.[c|h]" | xargs ctags -f ${WORKDIR}/tags
find /usr/include -name "*.h" | xargs ctags -a ${WORKDIR}/tags

cd /home/mzh/pptp-master/

chmod a+x ./tags.sh

./tags.sh  # 生成tags文件

set ts=4
set sw=4
set tags=/home/mzh/pptp-master/tags

如果要切换项目, ; set tags=/home/mzh/pptp-master/tags 注释掉，再加一行用其他项目的tags

[mzh@vultr pptp-master]$ grep -rn "int main(" .
./pptp.c:190:int main(int argc, char **argv, char **envp)
./tags:139670:main    /home/mzh/pptp-master/pptp.c    /^int main(int argc, char **argv, char **envp)$/;"    f
