Hi all, a crazy ideia just crossed my mind ? Is there a command that allows me to "glue" to text files together line by line ? more or like the inverse operation of 'cut' ... a vertical "cat" :P # cat abc a b c # cat 123 1 2 3 # vert_cat abc 123 > a1b2c3 # cat a1b2c3.txt a1 b2 c3 # :) Is there such a 'vert_cat' :) thx Joao
