Access, Modify, Change Time of Linux File

All these 3 time can be viewed by "stat " command.

Access time is influenced by read operation, such as command cat, more, less, head, tail, grep, sed, etc. This time is queried by "find . -atime -1", and can be set by "touch -a" command;

Change time is the time when inode is changed, which influenced by command mv, chmod, chown, etc;

Modification time is the time the content of the file changed, and be listed by "ls -l" command. It's influenced by command vi, etc, and can be set by "touch -m" command;

"touch -t" set access and modification time to the specified time;
