How to specify a range of fields?

To specify a range of fields using the cut command, you can use the -f option followed by the range in the format start-end.

For example, if you want to extract fields 1 to 3 from a comma-separated file, you would use the following command:

cut -d ',' -f 1-3 filename.txt

In this command:

• -d ',' specifies that the delimiter is a comma.
• -f 1-3 indicates that you want to extract fields 1, 2, and 3.

You can also combine ranges and individual fields. For example, to extract fields 1, 2, 3, and 5, you would use:

cut -d ',' -f 1-3,5 filename.txt

This command will extract fields 1 through 3 and field 5 from each line of the file.
