Using lseek(2) with an offset past the end of the file and then writing something. To try it without writing C (or perl etc.) code, you can do something like dd if=/dev/zero of=f bs=1024k seek=100000 count=1 du -h f ls -lh f As you can see, you have a file that seems like being ~100GB, but actually consumes ~1MB. Not all filesystems support this - if you do the same e.g. on fat, zeros will be written to the file. -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
