and want remove last character if pipe (|).

kure|hiroshima kure|hiroshima kure|hiroshima no matching aachen darmstadt mulheim aachen 

thanks in advance

you can use sed this:

$ sed 's/|$//' file kure|hiroshima kure|hiroshima kure|hiroshima no matching aachen darmstadt mulheim aachen 

it looks | $ (which means "end of line") , deletes it.

note can use sed -i in case want in-place edit.
