in reply to perl one liner print columns 2.. last

Works for me. I would suggest that you show us (an extract) of your input file.

echo 1 2 3 4 5 6|perl -lane 'print $F[1]..$F[-1]' 23456

Are your columns separated by whitespace?

Update: Of course, this doesn't work, for the reasons given by LanX in his reply to this (too hasty) posting.

    Sorry thats wrong, your test data is misleading you :)

    you are calculating the numerical range between 2 and 6, which by accident was your input.

    now change the input in between:

    > echo - 2 - - - 6|perl -lane 'print $F[1]..$F[-1]' 23456

    but a slice works: =)

    > echo - 2 - - - 6|perl -lane 'print @F[1..$#F]' 2---6
