多了不再赘述,看以下解释
st_atime
Time when file data was last accessed. Changed by thefollowing functions: creat(), mknod(), pipe(),
utime(2), and read(2).
st_mtime
Time when data was last modified. Changed by the fol-
lowing functions: creat(), mknod(), pipe(), utime(),
and write(2).
st_ctime
Time when file status was last changed. Changed by the
following functions: chmod(), chown(), creat(),
link(2), mknod(), pipe(), unlink(2), utime(), and
write().
ctime不是create。是change的意思。
注意:
ls 中的时间。是mtime
ls -lc filename 列出文件的 ctime
ls -lu filename 列出文件的 atime
ls -l filename 列出文件的 mtime
