Help with zipping files
Hi,
I have come across a requirement in which I need to zip files. This is fine but the requriement has one conditions like below:
One .z file can not have more than 10,000 files
Now in the directory I have several files liek below:
aaa_file_10_00001.txt
aaa_file_10_00002.txt
aaa_file_20_00001.txt
aaa_file_30_00001.txt
aaa_file_10_00003.txt
...........................
...........................
...........................
aaa_file_30_00750.txt
aaa_file_30_10005.txt
If i have to zip the above files, I will have 4 .z files. One for files like aaa_file_20_*.txt, one for files like aaa_file_30_*.txt and two for files like aaa_file_10_*.txt I am planning to move files of different type (diferentiated by 3rd field in the file name) to a temporary directory and zip them. But the problem is I can not zip more than 10,000 files together. How do I move files of type aaa_file_10_*.txt from 1-10000 (this is the value in 4th field of the file name )first, zip them and then move the reamining 10001-10005.
Using a loop is not a good option as per my understanding. Is there any other way of doing it which will not have impact on performance ?
Thanks
