COLRM(1)                  BSD General Commands Manual                 COLRM(1)

NAME

     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.

     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 decre-ment decrement
     ment the column count by one.

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in
     environ(7).
