there is an -a switch in the /filter command which allows u to sort according to your alias which will return 1/0/-1
it works like that so it moves every time on two lines and compare between them with an ALIAS, the alias should return -1 if u want to replace their place and if u want it to stay like it was u return 0 or 1
note that in the alias, $1 is the 1st line and $2 is the 2nd line
