UNIX for Dummies Questions & Answers

Hi,

Please give me more details on the following examples, about "mtime" option.
When I try this, I could not get the expected output, please help.

Code:

 
find . -mtime -1 -print
find . -mtime +1 -print
find . -mtime 1 -print

How do I get the files modified between two dates, say from 16-Jun-2012 to 25-Jun-2012.

Thank you.

-1 means less than 24 hours old
1 means precisely 86400 * 24 seconds (one day) old
+1 more than one day old

Code:

#16-Jun-2012 to 25-Jun-2012
touch -t 201206160000 dummy1
touch -t 201206252359 dummy2

find . -type f \( -newer dummy2  -a ! -newer dummy1 \)

Hi Jim,

Thanks a lot!

I understood the use of -1, +1, 1 for mtime parameter.

The below 'touch' command creates files on the two given dates as 16th and 25th Jun appropriately,

touch -t 201206160000 dummy1
touch -t 201206252359 dummy2

But, the below find command does not give any output, I know "type -f" searches for file types and not sure what does the values inside the brackets do, can you please provide more details.

find . -type f \( -newer dummy2 -a ! -newer dummy1 \)

It think that the filenames were reversed!
Try:

Code:

find . -type f \( -newer dummy1  -a ! -newer dummy2 \)

The escaped backets \( \) enclose the condition and protect the brackets from being interpreted by the Shell.
The -a means "and" .
The ! mens "not".


Ps. Some versions of touch have accuracy to the second. See man touch on your system.

mtime means modified time. so it's the last time the file was modified. maybe youw ant ctime which is the create time
