Bash tail

title: Bash Tail

## Bash Tail
tail is a program to display the tail end of a text file. If no option is given, tail shows the last 10 lines of a given file.

Usage

tail [options] [file_names]

Commonly used options:

• -f – Display the last lines and then monitor the file. If new lines are added to the file, tail updates the display.
• -F – Same as -f but if the file/log is rolled it will continue with the new file/log.
• -c NUM – display the last NUM bytes of the file.
• -n NUM – display the last NUM lines, instead of the last 10 Examples View the last several lines from file log.txt

 tail log.txt

 tail -n 15 log.txt

Show only the last line from file log.txt

tail -n1 log.txt
