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 speci-
     fied, 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)
