How to remove the end of line character from the beginning of a line?

Question

bash

Good afternoon!
Original line:

[email protected]:# sed 's/\t/:/g' /tmp/list | cut -f6 -d: | sort -u | grep QQ
QQ 7 96559

When you try to add something to the end of a line, the first character in the line is replaced. How to fix?

[email protected]:# sed 's/\t/:/g' /tmp/list | cut -f6 -d: | sort -u | sed 's/$/1/'
1Q 7 96559

It is normally added to the beginning.

[email protected]:# sed 's/\t/:/g' /tmp/list | cut -f6 -d: | sort -u | sed 's/^/1/'
1QQ 7 96559
