I guess your problem can easily be solved with awk alone, but since I don't know awk...
A possible alternative solution can be this one: knowing which is the colums delimiter in your file (if it isn't a single char, there are workarounds), you can use cut to select them one by one. If a column is made by "-9"s and nothing else, then if you uniq it you'll get a single "-9". If so, you can remember the colum number (to later discard the column).
Something like:
Save it as myscript, and then give it exec permission with: chmod +x myscript.
Usage: ./myscript inputfile or ./myscript inputfile >newfile.

colrm
COLRM(1) BSD General Commands Manual COLRM(1)NAME
colrm -- remove columns from a file
SYNOPSIS
colrm [start [stop]]
DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read
from the standard input. Output is written to the standard output.
If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec-
ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not
zero.
Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).
EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO awk(1), column(1), cut(1), paste(1)HISTORY
The colrm command appeared in 3.0BSD.
