Question 2

tail

• c
• f
• F
• n
• q
• s

Answer 2

• c, –bytes=[+]NUM, Output the last NUM bytes; or use -c +NUM to output starting with byte NUM of each file.
• f, –follow[={name|descriptor}], Output appended data as the file grows; an absent option means ‘descriptor’
• F, Same as –follow=name –retry
• n, –lines=[+-]NUM, Output the last NUM lines, instead of last 10; use -n +NUM to output starting with line NUM.
• q, –quiet, –silent, Never output headers giving file names.
• s, –sleep-interval=N, With -f, sleep for approximately N seconds between iterations.
