Ubuntu Linux delete a file and prompt before every removal

To get confirmation before attempting to remove each file pass the -i option to the rm command on Ubuntu Linux:
vivek@nixcraft:~$ rm -i fileNameHere
vivek@nixcraft:~$ rm -i dellLaptopSerials.txt

Force rm command on Ubuntu Linux to explain what is being done with file

Ubuntu Linux delete all files in folder or directory

Ubuntu Linux delete file begins with a dash or hyphen

If the name of a file or directory or folder starts with a dash (- or hyphen --), use the following syntax:
vivek@nixcraft:~$ rm -- -fileNameHere
vivek@nixcraft:~$ rm -- --fileNameHere
vivek@nixcraft:~$ rm -rf --DirectoryNameHere
vivek@nixcraft:~$ rm ./-file
vivek@nixcraft:~$ rm -rf ./--DirectoryNameHere

Do not run ‘rm -rf /‘ command as an administrator/root or normal Ubuntu Linux user

rm -rf (variously, rm -rf /, rm -rf *, and others) is frequently used in jokes and anecdotes about Ubuntu Linux disasters. The rm -rf / variant of the command, if run by an administrator, would cause the contents of every writable mounted filesystem on the computer to be deleted. Do not try these commands on Ubuntu Linux:
vivek@nixcraft:~$ rm -rf /
vivek@nixcraft:~$ rm -rf *
