Hi

10801 10802

11406 11415 11422 11426
11513 11514 11515 11516 11517 11518 11519 11520 11521 11522 11523 11524 11525 11530
11604 11608 11611
11717 11718 11719 11722 11725 11726 11727 11728 11729 11730 11731 11732 11736

Or, without external commands, if your shell has the "printf" builtin
(for example if you use shell, other than sh):

printf "%s\n" $(<file)
