python

Very frequently there is a need to monitor a presence of a file in some directory, this maybe needed for:

• Automated deployment jobs - every time a new bundle is uploaded, deploy it
• Synch processes - there are multiple clustered servers, and they need to have same files on them
• Error file - if file is ever present, then there is an error - send an email

write a program that will take a command line argument of full path and prints True if the file/directory at the provided location is present and False if it doesn't Change program such that it runs indefinitely, monitoring a file/directory at a certain location and if the file disappears, then the program should print "Alert"
