colrm
—
remove columns from a file
colrm
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.
The colrm
command appeared in
1BSD. It was completely rewritten for
4.4BSD.
