Question

Unix scripting - Date cmd - if ne to today then move?

Asked by: Westez

I'm asking for help in writing a script to move some log files.  I'm stuck on the date cmd.  I want to move any file that ends in .log and whose date is not equal to today.  The o/s is Redhat's linux.   I've read the man page on the date cmd, and I'm searching for examples on how this is done, but I haven't found it yet.  Would somebody help me out with a bit of code? Here's what I've got and this works for me, what I need help with is to figure out how to select the files whose date is not equal to today's date. Thanks

#! /bin/sh
cd /opt/log
mv 2009-05-10*.log /var/httplogs/
cd /var/
tar -cvf 2009-05-10.tar /var/httplogs/
gzip 2009-05-10.tar

USER="username"
PASS="userpassword"
FTPSERVER="servername.domain"
ftp -i -n $FTPSERVER << EOF
user $USER $PASS

prompt off
cd /tmp/
put 2009-05-10.tar.gz
bye

I'm in the Central Time zone.  A lot of the code I've been checking out mentions the timezone.

you should do it with the find command
i will send you the syntax

 

by: 0renPosted on 2009-05-13 at 21:50:29ID: 24381812

find ./ -ctime -10
will find files that was created in the last 10 days
find ./ -ctime +10
will find files that was created before the last 10 days
find ./ -name "*.log"
will find all *.log files
you can combine and ls them
find ./ -ctime -10 -name "*.log" -exec ls {} \;

 

by: 0renPosted on 2009-05-13 at 21:51:20ID: 24381817

you can also use atime - access time
                           mtime - modification time

and many others

just post what you need to do

 

by: 0renPosted on 2009-05-13 at 21:59:47ID: 24381839

will find files 10 created 10 days ago
find ./ -ctime 10

You can use grep to exclude todays files, eg:

#!/bin/bash
today=$(date +%Y-%m-%d)
 
cd /opt/log
ls *.log | grep -v $today | xargs -i mv {} /var/httplogs

Hey guys thanks a lot.  Tintin your solution works great.  

Oren - I like your approach because it allows me to leave a few days worth of logs on the server.  I want to apply this same type of script to a firewall once I'm done with the web server. And I want to leave 5 days worth of logs on the firewall.

Would you modify this line of code so it moves the files to /opt/log/?
find ./ -ctime -10 -name "*.log" -exec ls {} \;  

Tintin - Would you modify your code so it leaves a few days worth of log files on the server?

If I'm over stepping the rules of fair play here let me know and I'll close out this question and open a new one.

 

by: TintinPosted on 2009-05-14 at 15:13:16ID: 24390456

If you want  to keep a few days worth, then find is easier

find /opt/log -name "*.log" -mtime +5 | xargs -i {} /var/httplogs

 

by: TintinPosted on 2009-05-14 at 15:13:55ID: 24390462

Whoops, the above should be

find /opt/log -name "*.log" -mtime +5 | xargs -i mv {} /var/httplogs

Tintin - works great just like the first solution.  

Thanks to both of you for your for your suggestions and solutions.

Hi,

Apologies for hijacking the thread, but my problem is very similar to this and requires some tweaking.
Finding the files except for 2 for example works OK for me, but moving part needs changing. Because of the nature of the application I am executing this command from, I have effectively 3 concerned locations:
 - the home folder where I am going to execute the command from
 - the location of the folder I want to find the files in (different to above)
 - the location of the folder I want to move the files to (different to above)
 So, say I have the "test2.csv" and "test3.csv" /apps/home/source among many other files. I want to move all files except for the 2 above to /apps/home/target.
And my login location (from where I can only execute the find and move command) is /apps/dsbin/.

Does anybody have any idea how I can achieve this?

Thanks,

Benak
