COLRM(1)		    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	execu-
       tion of colrm as	described in environ(7).

EXIT STATUS
       The colrm utility exits 0 on success, and >0 if an error	occurs.

EXAMPLES
       Show columns below 3 (c)	and above 5 (e):

	     $ echo -e "abcdefgh\n12345678" | colrm 3 5
	     abfgh
	     12678

       Specifying a start column bigger	than the number	of columns in the file
       is allowed and shows all	the columns:

	     $ echo "abcdefgh" | colrm 100
	     abcdefgh

       Using 1 as start	column will show nothing:

	     $ echo "abcdefgh" | colrm 1

SEE ALSO
       awk(1), column(1), cut(1), paste(1)
