Linux in a Nutshell, 6th Edition

Name

colrm

Synopsis

colrm [start [stop]]

Remove specified columns from a file, where a column is a single character in a line. Read from standard input and write to standard output. Columns are numbered starting with 1. Begin deleting columns at (including) the start column, and stop at (including) the stop column; if stop is not given, delete all columns to the end. Entering a tab increments the column count to the next multiple of either the start or stop column; entering a backspace decrements it by 1.

Example

colrm 3 5 < test1 > test2
