The command "colrm ${1 1}" is used to remove a specific column or range of columns from a text file or input stream.

Here's a breakdown of the command components:

• "colrm" is the actual command being executed, which stands for "column remove".
• "${1 1}" is a parameter passed to the command. Here, the variable "$1" refers to the first argument passed to the command when executing the script, and "1" indicates the start and end column to be removed.

For example, if you run the command "colrm ${1 1}" on a text file or input stream, it will remove the first column from each line of the given input. The resulting output will contain the input without the first column.
