Help - compress file one day ago
Hi All,
I'm a new member of this Forum. I have need your help to handle this request.

"Compress a file name not of today but of yesterday only".

For example
Code:
0 mar 08:00 TEST_RPT_STATUS_M1I_CMI20120320.xls
20 mar 08:00 TEST_RPT_STATUS_M1I_CMI20120320.rep
21 mar 08:00 TEST_RPT_STATUS_M1I_CMI20120321.xls
21 mar 08:00 TEST_RPT_STATUS_M1I_CMI20120321.rep
22 mar 08:00 TEST_RPT_STATUS_M1I_CMI20120322.xls
22 mar 08:00 TEST_RPT_STATUS_M1I_CMI20120322.rep
23 mar 11:39 TEST_RPT_STATUS_AAAAAAAAAAAAAA.log
23 mar 11:39 TEST_RPT_STATUS_BBBBBBBBBBB.log

If I use this Unix/Linux command
Code:
find /home/user1/LOGS -mtime -1 -type f -iname "TEST_RPT*" -exec gzip -f '{}' ';'

only the files of today will be compressed. If I set -2 as mtime I find the files of today and of yesterday compressed.

I need to use compress ONLY the files of yesterday (Here 22 mar).

Any suggestion will be well appreciated.

Thanks in advance for your kind support.

Regards,

Giovanni

find
Hi,

Greetings!!! Welcome to the unix and linux forum!!!!

Code:
find /home/user1/LOGS -mtime +1 -type f -iname "TEST_RPT*" -exec gzip -f '{}' ';'

-1 in mtime says to the find command that, get the files are created with in one day.
+1 in mtime says to the find command that, get the files are created more than one day.

Please use code tags for data samples and codes.

Cheers,
RangaSmilie

Welcome.

The find command is a weird one since the switches like -mtime etc. usually will list a range of files (i.e. +1 files older than a day, etc.). One way to get only the files created the previous day, is to use a combination of boolean operators and the -daystart switch (see find man page):

Code:
find . \( -mtime -1 -and -not -daystart -mtime 0 \)

Hope this helps.

Hi Thanks for your quick reply.

The Unix command is the following
Code:
find /home/user1/LOGS  \( -mtime -1 -and -not -daystart -mtime 0 \) -type f -iname "TEST_RPT*" -exec gzip -f '{}' ';'

No error is returned by the script but no file is compressed.

Any suggestion will be well appreciated.

Thanks,

Regards,

Giovanni

if you use GNU find then try this Smilie
Code:
# find . -daystart -type f -mtime 1

so
Code:
# find /home/user1/LOGS -daystart -mtime 1 -type f -iname "TEST_RPT*" -exec gzip -f '{}' ';'

Hi,
Sorry again for the trouble but the message returned is the following
Code:
Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]

Any idea?

Thanks in advance.
