Perl solution:

perl -lane 'splice @F,0,2; print join " ",@F' file

These command-line options are used:

• -n loop around every line of the input file, do not automatically print every line

• -l removes newlines before processing, and adds them back in afterwards

• -a autosplit mode – split input lines into the @F array. Defaults to splitting on whitespace

• -e execute the perl code

splice @F,0,2 cleanly removes columns 0 and 1 from the @F array

join " ",@F joins the elements of the @F array, using a space in-between each element

If your input file is comma-delimited, rather than space-delimited, use -F, -lane

Python solution:

python -c "import sys;[sys.stdout.write(' '.join(line.split()[2:]) + '\n') for line in sys.stdin]" < file
