man ls只告诉我以下的信息:
-c Uses the time of last modification of the i-node for either sorting (when used with the -t flag) or for displaying (when used with the -l flag). This flag must be used with either the -t or -l flag, or both. 即“最近一次i节点修改时间”
-l (Lower case L) Displays the mode, number of links, owner, group, size (in bytes), and time of last modification for each file. If the file is a special file, the size field contains the major and minor device numbers. If the time of last modification is greater than six months ago, the time field is shown in the format month date year where as files modified within six months the time field is shown as month date time format. 即“最近一次修改时间”
-u Uses the time of the last access, instead of the time of the last modification, for either sorting (when used with the -t flag) or for displaying (when used with the -l flag). This flag has no effect if it is not used with either the -t or -l flag, or both. 即“最近一次访问时间” |
