The command "cut --${characters}=${1} ${filename}" is used to extract specific characters or fields from a text file. Here's an explanation of each component:

• "cut": It is the command that is used to extract specified parts from files or standard input.
• "--${characters}=${1}": The "--${characters}=" portion specifies the type of units to be extracted, whether characters, bytes, or fields. The "${1}" represents the number or range of units to be extracted. These can be replaced with actual values or variables.
• "${filename}": It specifies the name of the file from which the extraction is to be made.

For example, if you run the command "cut --characters=1-5 filename.txt", it will extract the first five characters from the file "filename.txt" and display the result.
