回复 4# cjaizss
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.0 (Santiago)
# ps -ef | grep -w vim
kkk 10071 9970 0 19:37 pts/0 00:00:00 vim tmp2
root 10073 9997 0 19:37 pts/1 00:00:00 grep -w vim
strace 的输出显示vi使用了unlink删除，但因为此文件还在被vi进程打开，所以kernel不会删除该文件，vi随后写入了修改的内容，这应该是为什么inode没有变化的原因。
多谢cjaizss！！！
