How to find the files that are created in the last hour in unix

How to find 开发者_JAVA百科the files that are created in the last hour in unix

---

If the dir to search is srch_dir then either

$ find srch_dir -cmin -60 # change time 

or

$ find srch_dir -mmin -60 # modification time 

or

$ find srch_dir -amin -60 # access time 

shows files whose metadata has been changed (ctime), the file contents itself have been modified (mtime), or accessed (atime) in the last hour, respectively.

ctime is non-unintuitive and warrants further explanation:

ctime: Unlike mtime, which is only related to the contents inside a file, changed timestamp indicates the last time some metadata of a file was changed. ctime refers to the last time when a file’s metadata. For example, if permission settings of a file were modified, ctime will indicate it.

UNIX filesystems (generally) don't store creation times. Instead, there are only access time, (data) modification time, and (inode) change time.

That being said, find has -atime -mtime -ctime predicates:

$ man 1 find
...
-ctime  n
        The primary shall evaluate as true if the time of last change of
        file status information subtracted from the initialization time,
        divided by 86400 (with any remainder discarded), is n.
...

Thus find -ctime 0 finds everything for which the inode has changed (e.g. includes file creation, but also counts link count and permissions and filesize change) less than an hour ago.

the basic code is

#create a temp. file
echo "hi " >  t.tmp
# set the file time to 2 hours ago
touch -t 200405121120  t.tmp 
# then check for files
find /admin//dump -type f  -newer t.tmp -print -exec ls -lt {} \; | pg

---

find ./ -cTime -1 -type f

OR

find ./ -cmin -60 -type f

---

sudo find / -Bmin 60

From the man page:

-Bmin n

True if the difference between the time of a file's inode creation and the time find was started, rounded up to the next full minute, is n minutes.

Obviously, you may want to set up a bit differently, but this primary seems the best solution for searching for any file created in the last N minutes.

To find files which are created in last one hour in current directory, you can use -amin

find . -amin -60 -type f

This will find files which are created with in last 1 hour.
