remove columns from a file
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 specified, 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.
LC_CTYPE environment variables affect the execution of
colrm as described in environ(7).
colrm utility exits 0 on success,
and >0 if an error occurs.
