The ps command is used to display information about the active processes running on a computer. There are various options you can use to display different sets of information about each process. You should read the man page for this command to get familiar with them.
Following the options of the command is an optional name of a file containing a list of bad process names to search for as the command given to start a process, if the file name is not present do not place any restrictions on which processes are displayed.
Make sure your program is properly commented. Include a sample output that shows the normal full output of a ps command, then the filtered output based on using your script
3) Body check - a specified file will contain a list of words that are commonly found in the bodies of spam email. These words may also occur in regular email, so finding just any word is not enough to label an email as spam. It is necessary to find several occurrences, so you can set a threshold and if the total number of occurrences is greater than that threshold the email is considered spam. Instances of a bad word as a substring of another word do not count as on occurrence. It is also common that spammers type words in all captial letters. If a bad word is found in the email body, and it is in all capital letters, it should count as two occurrences.
Your script should take a set of command line arguments to specify which of the above tests should be performed on a particular email message. If the -F option is given, a sender check should be performed. If the -S option is given, a subject check should be performed. If the -B value option is given, then a body check should be performed, and the corresponding value is the threshold for determining if the number of occurrences is great enough. At least one of these options must be specified or it is an error. The names of the supporting files that contain lists of words for the various checks can be hard-coded into your program.
