Dec 2, 2023 at 12:11 comment added Lena Schimmel Warning: using dd like this will slow down the whole process by several orders of magnitude. bs=1 sets the block size to a single byte which prevents efficient file IO. Switching the parameters, e.g. bs=3 skip=1 helps a little bit, but using tail is much more efficient anyway. I did not test sed for speed.

Add fix from comments (finally) and add extra information about that.

Oct 25, 2012 at 13:55 comment added Alvin SIU Thanks for your help. Both the sed and the tail commands work in AIX 6.1. For the dd command, it should be dd if=A_FILE bs=1 skip=3 in AIX 6.1
