file date check 1

[dwcasey]

I am wanting to check the date of all files in a directory and if they are not today's date, send an alert ( email, log, etc. )

If I run:

find . -type f -mtime +1

in my directory where the files are, I get files that are 1 day old. This will work, but I was just wondering if there was a more 'elegant' way to do this?

what os?

Did you want < 1 day old or "today" (localtime) date ?

I don't know if it's more elegant or not, but a common method for finding files created just today is to create a file at midnight, and use find's -newer option:

# untested

touch -t 200810150000 /tmp/neweroptionfile
find . -type f -newer /tmp/neweroptionfile -print

The above find command returns only files with a modification time after midnight on 10/15/2008. You can use the same method to find files modified within a given date range:

# untested
# find files modified in the first quarter of 2008

touch -t 200801010000 /tmp/newerstart
touch -t 200803312359 /tmp/newerend

find . \( -newer /tmp/newerstart -a \! -newer /tmp/newerend \) -print

Believe "touch -t" is only in Linux or equivalent.

If you don't have that, one could just parse an ls long listing for the date time stamp since a recent file does not have the year explictly, and all that don't conform must be from a previous 'day'.

touch -t is pretty widely available (Solaris, AIX, HP-UX, ...).

Checked around, Anni is right on. Guess I was thinking like old 4.3 BSD touch.

Cool.

olded - here's a star for teaching me touch -t! Thank you

Find has always worked well for something like this, unless you need to find something in a specific subdirectory and don't want it to transcend directories. Then it's usually been easier to grep stuff out of ls...
