You can use the vim sort command (:help sort) instead of gnu sort.
Moreover it's portable.

Thank.
But there will be a problem if I use the above script to update the tags file.
I tried to use sort command, but it still doesn't work.
If I have the code file as follow:
---------tmp1.h-----------
class tmp1
{
public:
void print1(){}
};
---------test.cpp----------
#include "tmp1.h"
class world{
public:
void worldprint(){}
};
int main()
{
tmp1 t1;
t1.
}
If I use the following function,
function! SaveUpdateTags()
write
call system('grep -v "'.expand('%').'" tags > tags2')
let tags = system('ctags --c++-kinds=+p --fields=+iaS --extra=+q -f -
'.expand('%').' | sort >> tags2')
call system('sort tags2>tags')
call system('mv -f tags2 tags')
return ''
endfunc
The tags file will be like this:
main test.cpp /^int main()$/;" f signature:()
print1 tmp1.h /^ void print1(){}$/;" f class:tmp1
access:public signature:()
tmp1::print1 tmp1.h /^ void print1(){}$/;" f class:tmp1
access:public signature:()
tmp1 tmp1.h /^class tmp1$/;" c
worldprint test.cpp /^ void worldprint(){}$/;" f class:world
access:public signature:()
world test.cpp /^class world{$/;" c file:
world::worldprint test.cpp /^ void worldprint(){}$/;" f
class:world access:public signature:()
How do I sort will make
worldprint test.cpp /^ void worldprint(){}$/;" f class:world
access:public signature:()
below
world test.cpp /^class world{$/;" c file:
