Shell Programming and Scripting

Hi All,

Could you please help me in searching files in a better way satisfying the below conditions

I want to search files in a path whose access time is more than 5min and less than 60 min and whose Byte size is greater than zero

For this, i am using the below command, but it is consuming lot of time. Can someone of you please suggest me a better option .

Code:

find /home/sparks -type f \( -mmin +5 -a -cmin -60 \) -size +0 -ls | egrep -v '|subscriptions|sent|outbox'

Thanks in advance !!!

I don't think that there is any "better" option than to use find. Still, your find-command could well be optimized by throwing out the pipe.

Instead of:

Code:

find /home/sparks -type f  \
                         ! \( -name "subscriptions*" -o -name "sent" -o -name "outbox*" \)
                         \( -mmin +5 -a -cmin -60 \) -size +0 -ls

You might have to fine-tune the file-globs a bit, depending on how exact your file mask in egrep was phrased. Either way you will perhaps save execution time because you don't have to process all the data only once instead of twice.

I hope this helps.

What OS ? What FileSystem?
How many subdirectories? files?

Is it really access time you are interested in or modified time?
cmin change of file status.
mmin modification time.
You are comparing apples and PCs.
amin is access time
Many systems have volumes with atime updates disabled!

If you are really looking for an non empty file
-not -empty may be better.
But if you are looking for a file that has some content specifying a more specific size range may reduce the number of other tests performed.

I don't know if find optimize the tests? By that I mean:
Does it matter what order the options are specified in?
Anyone out there know??
