(Linux)

Write a shell script to solve the following problem:

Write a shell script that will create a backup of the file specified as an argument. This backup file will be saved in ~/backups/ with ?date appended to the original file name. date shall be in the form yymmdd:HHmm. Your script should check to make sure the ~/backups/ directory exists before copying files, creating the directory if necessary. Ensure your script will properly accept a file argument with path information and strip any path information prior to copying the file.

For example, the file ~/test/lab37q1.sh would be backed up to ~/backups/lab37q1.sh?100407:1340

The basename command may be helpful here.

The date command can be used to display the date and time in various formats.
