Shell Programming and Scripting

Thanks, Methyl.

It was good to explore about uname & shell. I just knew about uname -a.

Coming to back on the trace -
All the files under same directory - on the same mound point. None of the file has funny characters like *,&,etc..

Your analysis are correct - for the size & numbers.. So let's continue with that -

I want to compress them all. -exec will certainly not work..

Code:

find ./ -type f -mtime +1176 | gzip -c > temp.gz

Above stuff is not sufficient for millions of files... It creates temp.gz but I am not sure -- WHETHER THIS WILL WORK WITH THOUSANDS OF FILES OR NOT?

Even below code is not what serves the problem -

Code:

find ./ -type f -mtime +1176 -print | xargs -n1 -i tar -cvf {}

Creating a temp file - which contains name of all the files & then accessing it to compress the files - look a long way around to me. Cant we do it in single line command?

Very similar question is posted in my different thread -
https://www.unix.com/unix-dummies-que...es-one-go.html

It's good if you can migrate - sorry for the confusions - Actually the tasks are different but associated here, so ..

(You may reply on the new thread or here as well , i am just concerned about solution !! )

Thanks,
Kedar

Code:

find . -type f -mtime +1176 | 
  xargs tar cf - | gzip > all_"$(date +%F)".tgz

On a GNU system:

Code:

find -type f -mtime +1176 -print0 | 
  xargs -0 tar c | bzip2 > all_"$(date +%F)".tbz2

Thanks, Radoulov.

Will try this & let you know - if i am stuck up any where..

1) Will this delete existing files or that I will have to do manually?
(It would be good if this command can delete as well - otherwise i will have to fire this costly operation - find - once again to delete them. Although not a big problem..)

2) I am not able to untar this directly. what's the way to check if this tar is safe (okay) ?

Below command returns me errors..

Code:

tar -tvf older_then_2008_2.tgz
tar: directory checksum error

I need to make sure - the files are still good - before i delete uncompressed files...

Thanks!

No, it will only archive the files. You should use another command to remove them:

Code:

find . -type f -mtime +1176 -exec rm +

If your find implementation does not support the + operator,
use xargs:

Code:

find . -type f -mtime +1176 | 
  xargs rm

You should use something like this:

Code:

gzip -dc older_then_2008_2.tgz | tar -tvf -

We really need to know what Operating System you are running and which is your preferred Shell.
Many unixes will not deal with single files above 2Gb - especially in tar. There may be other limitations in your OS which will require breaking the task down into manageable units.

hi,

the error is related to the largefile size , your mv command is failing when the file size more then 2 gb.

please be advised that your mv commad coming from large file aware directory..
type which mv ------> to get the current location of mv. if /bin
you can try /usr/local/bin/mv (exclusive path in find command)

instead of mv you have to specify the exclusive path.

i had this problem and corrected it this way.
you can check the man page of solaris for ---largefile
your file size is 5+gb.
hope it help
