The syntax is pretty simple; just run the stat command followed by the file's name whose last modification date you want to know, as shown in the example below. As you can see, the output shows more information than previous commands.
I can reproduce your problem if there are no files in the directory that were modified in the last hour. In that case, find . -mmin -60
returns nothing. The command find . -mmin -60 |xargs ls -l
, however, returns every file in the directory which is consistent with what happens when ls -l
is run without an argument.
To make sure that ls -l
is only run when a file is found, try:
find . -mmin -60 -type f -exec ls -l {} +
The problem is that
find . -mmin -60
outputs:
.
./file1
./file2
Note the line with one dot?
That makes ls
list the whole directory exactly the same as when ls -l .
is executed.
One solution is to list only files (not directories):
find . -mmin -60 -type f | xargs ls -l
But it is better to use directly the option -exec of find:
find . -mmin -60 -type f -exec ls -l {} \;
Or just:
find . -mmin -60 -type f -ls
Which, by the way is safe even including directories:
find . -mmin -60 -ls
To search for files in /target_directory and all its sub-directories, that have been modified in the last 60 minutes:
$ find /target_directory -type f -mmin -60
To find the most recently modified files, sorted in the reverse order of update time (i.e., the most recently updated files first):
$ find /etc -type f -printf '%TY-%Tm-%Td %TT %p\n' | sort -r
Manual of find:
Numeric arguments can be specified as
+n for greater than n,
-n for less than n,
n for exactly n.
-amin n
File was last accessed n minutes ago.
-anewer file
File was last accessed more recently than file was modified. If file is a symbolic link and the -H option or the -L option is in effect, the access time of the file it points to is always
used.
-atime n
File was last accessed n*24 hours ago. When find figures out how many 24-hour periods ago the file was last accessed, any fractional part is ignored, so to match -atime +1, a file has to
have been accessed at least two days ago.
-cmin n
File's status was last changed n minutes ago.
-cnewer file
File's status was last changed more recently than file was modified. If file is a symbolic link and the -H option or the -L option is in effect, the status-change time of the file it points
to is always used.
-ctime n
File's status was last changed n*24 hours ago. See the comments for -atime to understand how rounding affects the interpretation of file status change times.
Example:
find /dir -cmin -60 # creation time
find /dir -mmin -60 # modification time
find /dir -amin -60 # access time
I am working through the same need and I believe your timeframe is incorrect.
Try these:
You should be using 24 hours as your base. The number after -mtime should be relative to 24 hours. Thus -.5 is the equivalent of 12 hours, because 12 hours is half of 24 hours.
