The command "cut -${c} ${1} ${filename}" is used in a UNIX-like operating system to extract specific fields or columns from a file.

Here's a breakdown of the components:

1. "cut" - This is the actual command being used.
2. "-${c}" - The "${c}" is a variable that defines the specific field or column that is to be extracted from the file. For example, if "${c}" is equal to "3", it means the third column will be extracted.
3. "${1}" - This is another variable that represents the first argument passed to the command. In this context, it usually refers to a specific delimiter or separator used to split fields or columns in the file. For example, if "${1}" is equal to "," (comma), it means fields or columns will be separated by commas.
4. "${filename}" - This is the variable representing the file from which the fields or columns need to be extracted. It can be the actual filename or a path to the file.

Overall, the command takes the input file ("${filename}"), splits it into fields or columns based on a specified delimiter ("${1}"), and then extracts a specific field or column ("-${c}").
