Amend a line of input in multi-line mode. `amend-line N`, where the N in `amend-line N` represents line to replace.
Can also specify a range of lines using `amend-line N..M` syntax. Passing '!' as replacement content deletes the line(s) instead. Aliases: %N Can also specify a range of lines using `amend-line N..M` syntax. Passing '!' as replacement content deletes the line(s) instead. Aliases: %N
e.g amend-line 1 puts 'hello world! # replace line 1' e.g amend-line 1 puts 'hello world! # replace line 1'
e.g amend-line 1..4 ! # delete lines 1..4 e.g amend-line 1..4 ! # delete lines 1..4
e.g amend-line 3 >puts 'goodbye' # insert before line 3 e.g amend-line 3 >puts 'goodbye' # insert before line 3
e.g amend-line puts 'hello again' # no line number modifies immediately preceding line e.g amend-line puts 'hello again' # no line number modifies immediately preceding line
