check if file is modified today

[guif]

hi!
i would like to create a bash script to know if some Log's are modified today.
Normaly i go to the prompt and put:

ls -lha /var/log/cpu.log
ls -lha /var/log/mem.log
ls -lha /var/log/disk.log

Is it possible to create a script to make a simple exit?
For example:

CPU = OK
MEM = OK
DISK = OK


thanks!

do this work ?

#!/bin/bash

DIR=/var/log/
FILE1=cpu.log
FILE2=mem.log
FILE3=disk.log

if [[ -z $(find $DIR -atime -1 -name $FILE1) ]];
then
	echo "$FILE1 is ok "
fi

if [[ -z $(find $DIR -atime -1 -name $FILE2) ]];
then
	echo "$FILE2 is ok "
fi

if [[ -z $(find $DIR -atime -1 -name $FILE3) ]];
then
	echo "$FILE3 is ok "
fi

[guif]

it returns:

cpu.log [ FAIL ]
mem.log [ OK ]

files:

-rwxrwxrwx 1 tomcat oper 4.5M Nov 19 13:00 /var/log/cpu.log.log
-rwxrwxrwx 1 tomcat oper 1.1M Nov 19 13:00 /var/log/mem.log.log

why??? In two cases the date is today....

That is because you want to use the modification time (mtime) instead of the access time (atime).

whats the different between mtime and atime?
If I put atime the result is: OK and FAIL
and if i put mtime the result is: FAIL and FAIL.

why???

Look it up on google.

If I put atime the result is: OK and FAIL
and if i put mtime the result is: FAIL and FAIL.

Are you using the above script? If so, this is what it does: it uses the "find" program to look for files in your directory that were accessed less than one day ago and have a particular name. It then checks whether find printed anything (i.e. found such a file) and prints "OK" if it did not.

I suggest the following alternative:

touch -d 2008-11-19 midnight
for file in /var/log/{cpu,mem,disk}.log
  do if [[ $file -nt midnight ]]
    then echo $file
  fi
done
