Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.

$DATE isn't defined in that part of the code. If all are listed, that will not be necessarily wrong, if I understood it correct, since all green numbers of your example are less than 12.

Code:
$> ls -1
CCR20110720011001.CTRD
CCR20110720011501.CTRD
CCR20110720012001.CTRD
CCR20110720021001.CTRD
CCR20110720021501.CTRD
CCR20110720142001.CTRD
CCR20110720152501.CTRD
$> ls *CTRD| grep .*0[1-9]....\.CTRD
CCR20110720011001.CTRD
CCR20110720011501.CTRD
CCR20110720012001.CTRD
CCR20110720021001.CTRD
CCR20110720021501.CTRD

My bad, I just did only 1-10, not 1-12, so here you go:

Code:
ls *CTRD| grep -E ".*(0[1-9]|1[0-1])....\.CTRD"

thanks zaxxon for your quick answer.
i going to explain more to understand me well
we receive 12 file in the hour.
i want to list just the files from the 01 hour to 10 which the number of this files less than 12. i'm interested just by the first 10 hours.

Thanks

I am still not sure, sorry.

What I understood:
  • You get 12 files per hour.
  • You only want to list files that came from hour 01 to 10.

What I do not understand is:
Quote:
which the number of this files less than 12
So the 12 files per hour is fix and if there is 1 or more less than 12, in other words there is missing some of them, you want to see those, that have arrived, right?

Yu could try this:

Where i have a text file called hours.txt with:

Code:
CCR20110720011501.CTRD
CCR20110720012001.CTRD
CCR20110720012501.CTRD
CCR20110720021001.CTRD
CCR20110720021501.CTRD
CCR20110720022001.CTRD
CCR20110720032001.CTRD
CCR20110720032501.CTRD
CCR20110720032601.CTRD
CCR20110720032701.CTRD
CCR20110720032801.CTRD
CCR20110720032801.CTRD
CCR20110720102801.CTRD
CCR20110720113001.CTRD

This line:
Code:
sed 's/^[A-Z]..........\(0[1-9]\|1[0]\).*/\1/g' hours.txt |sed '/^C.*/d'| awk '{gsub(/CCR20110720/,"",$1); gsub(/.....CTRD/,"",$1); print}' hours.txt | sort |uniq -c |awk 'BEGIN { print "OCURRENCES  HOUR"; print "----  -----"} { if ($1 < 5 && $2 <= 10){ print $1 "\t"$2 }}'

Output is:
Code:
OCURRENCES  HOUR
----  -----
3       01
3       02
1       10

Am sure there's a shorter way Smilie
