Re: perl one liner print columns 2.. last

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
