Del files older than today

Shell Programming and Scripting
1

Hi all,
I have the following line in my script I need to delete all files that were not created today.

find . -type f -name '*.trm' -mmmin +1440 -exec rm {} \;

or

find . -type f -name '*.trm' -mtime +2 -exec rm {} \;

The issue is that we are still seeing files older than today.

Thanks for any help

Found the solution

find . -type f -name '*.trm' -mtime 1 -exec rm {} \;

-mtime 1 means 24...48 hours old.
-mtime +0 means 24 hours or older.

Hello

What I need is to delete all files from yestarday in this case I need to delete all files from the 22th.

I I use

find . -type f -name '*.trm' -mtime +0

find . -type -f ls |grep 'Jun 22' |  wc -l

this is wrong: -type -f ls
what does the following give you?

find . -type f -name '*.trm' -ls |grep 'Jun 22' |  wc -l

Also -atime/-mtime are relative specs - relative to the time of the execution.
From man find:

       -mtime n
              File's  data was last modified n*24 hours ago.  See the comments
              for -atime to understand how rounding affects the interpretation
              of file modification times.

       -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.

also

       find $HOME -mtime 0

       Search for files in your home directory which have been modified in the
       last twenty-four hours.  This command works this way because  the  time
       since  each  file  was last modified is divided by 24 hours and any re‐
       mainder is discarded.  That means that to match -mtime 0, a  file  will
       have  to  have  a  modification in the past which is less than 24 hours
       ago.

So you're not really comparing apples to apples...
If you want to identify the differences... instead of ...| wc -l spool both commands to files and find the differences (a file exists in one listing and not the other and vice versa) to see how the listings differ - this can easily be done with awk.

-daystart -mtime 1 means from yesterday
-daystart -mtime +0 means from yesterday or older.
GNU find required.
