HI all,

I need your help if someone can can help

In an directory I have

-rw-r--r-- 1 ggggg ggggg 196846 2007-04-04 19:46 rrrrr_20070404214503_44538.txt
-rw-r--r-- 1 ggggg ggggg 192037 2007-04-04 20:02 rrrrr_20070404220002_44539.txt
-rw-r--r-- 1 ggggg ggggg 182503 2007-04-04 20:16 rrrrr_20070404221503_44540.txt
-rw-r--r-- 1 ggggg ggggg 162382 2007-04-04 20:32 rrrrr_20070404223003_44541.txt
-rw-r--r-- 1 ggggg ggggg 168154 2007-04-04 20:46 rrrrr_20070404224502_44542.txt
-rw-r--r-- 1 ggggg ggggg 161118 2007-04-04 21:02 rrrrr_20070404230002_44543.txt
-rw-r--r-- 1 ggggg ggggg 151536 2007-04-04 21:16 rrrrr_20070404231502_44544.txt

using this
ls -l | awk '{if ( $8~/^ggggg/ ) print $6 "\t" $7 "\t" $8 }'
I can filter date, time and filename. Every 14 min from one machine, and every 16 min from other machine I got new file, as above, but time stamp is different, part 21:02, 21:16 and so on. I need to find out some solution how transfer most recent file from this directory to another machine using ftp. FTP implementation is not problem,and when I write script I will put it in cron table to run every 20 min and fetch last file transfered to that directory. But I can not realise my how select last recent file, in directory, because time parameter is changing every time the file is transfered to this directory. If anybody has some hint to direct, it would be very helpful.
I can use awk and shell scripting tools.

best wishes and regards

ls can sort by time. This will give you the most recent file:

Maybe a stupid question, but is there any information in the name of the files?

this part is the same
rrrrr_....20070404214503...._...44538.....txt

the part between ..... is some kind of time stamping but, I think it is easier to use time in format 21:15


any idea is welcome

If I understand you correctly, you can NOT use the time stamp of the file which is given by 'ls' because that time stamp changes whenever the file is transferred to that directory.

But the name of the file, and especially the part ...20070404214503... gives information about the time stamp. Is that correct?

A suggestion. If you have access to the directory that transfers the file to "this" directory, then examine `touch`. It has a "-r ref_file" option. So something like

may work for you.

This should be folowed by find.

Please post the result.

End

Unfortunately, i have not access to these machines which transfer files to this machine ( this directory ) I can only manipulate with files in " my " directory.

Thanks

You could extract the time stamp from the file name, if as you say, the time information is contained in the file name.

If your file name is: "rrrrr_20070404214503_44538.txt" then something like this should work:

It translates the file name into the time in seconds.
