Final answer:
The student's question is about creating a script that reads the last 10 entries of a log file without crashing if there are fewer entries. The student must write a program, preferably in Python, that employs exception handling to manage errors and ensures it can handle log files with less than 10 entries.
Step-by-step explanation:
The student is asking for a script that will read a log file and print the last 10 entries of the file. A robust programming solution is required to ensure that the script does not crash even if the log file contains fewer than 10 entries. Below is a python example that accomplishes this task:
# This Python program reads the last 10 lines of a log file
def tail(f, n):
with open(f, 'r') as file:
lines = file.readlines()
return lines[-n:]
def main():
log_file_path = 'path/to/your/logfile.log'
try:
last_10_lines = tail(log_file_path, 10)
for line in last_10_lines:
print(line.strip())
except FileNotFoundError:
print('Log file not found.')
except Exception as e:
print(f'An error occurred: {e}')
if __name__ == '__main__':
main()
It is necessary to replace 'path/to/your/logfile.log' with the actual path to the log file to be read. This script uses exception handling to manage scenarios when the log file does not exist or other potential errors that can occur while opening or reading the file.
