<\/p>\nHow to view Data from File Using Tail command with Different Options<\/strong><\/h2>\n
There are multiple ways to view data with the help tail command by using different options.<\/p>\n
Below are the options we can use with the tail command, and some of the options are explained with the help of examples.<\/p>\n
- \n
- -n(number of lines)<\/li>\n
- -c(number of bytes)<\/li>\n
- -q(verbose)<\/li>\n
- -f(follow)<\/strong><\/li>\n<\/ul>\n
How to use the tail command with \u2013n option <\/strong><\/h3>\n
The “-n” defines the number of lines to be printed on the screen starting from the end of the file. If the number is not supplied in the command, an error will be displayed. We can also write ‘-‘ with the number instead of the ‘n’ character with this command.<\/p>\n
The below-mentioned command will display the last 5 lines of the “linux1.txt” file<\/p>\n
\n\n
\n \n $ tail -n 5 linux1.txt<\/strong><\/pre>\n<\/th>\n<\/tr>\n<\/thead>\n<\/table>\n

<\/p>\nHow to use the tail command with \u2013c option <\/strong><\/h3>\n
The latest ‘”num” bytes from the provided file are printed. If the new line is counted as one character, it will be counted as a byte by the tail command if it is printed. It is required to type -c followed by any number, depending on the need. If there is a positive sign (“+”) before the number, it will be displayed by skipping the number of bytes from the beginning of the supplied file. If there is a negative sign (“-“) before the number, it displays the final number of bytes. If there is no “+” or “-” sign before the number, it will display the last number of bytes from the file supplied.<\/p>\n
The below-mentioned command will display the last 10 lines of the “linux1.txt” file. file.e<\/p>\n
\n\n
\n \n $ tail -c 10 linux1.tx<\/strong><\/pre>\n<\/th>\n<\/tr>\n<\/thead>\n<\/table>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2022\/02\/word-image-559.png\")
<\/p>\nThe below-mentioned command will display all data except the first 10 bytes of the “linux1.txt” file.<\/p>\n
\n\n
\n \n $ tail -c +10 linux1.txt<\/strong><\/pre>\n<\/th>\n<\/tr>\n<\/thead>\n<\/table>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2022\/02\/word-image-560.png\")
<\/p>\nHow to use the tail command with the \u2013q option <\/strong><\/h3>\n
If more than one file is specified, -q is used. As a consequence of this operation, the data from each file is not followed by the name of the file.<\/p>\n
The below-mentioned command will show the combined data of files “linux1.txt” and “linux2.txt” without specifying the file name, as it did in the output of “display data of multiple files” as shown above:<\/p>\n
\n\n
\n \n $ tail -q linux1.txt linux2.txt<\/strong><\/pre>\n<\/th>\n<\/tr>\n<\/thead>\n<\/table>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2022\/02\/word-image-561.png\")
<\/p>\nHow to use the tail command with the \u2013f option<\/strong><\/h3>\n
This option is mostly used by system administrators to keep track of the size of log files generated by various Unix programs as they run. This option displays the file’s last 10 lines and updates when new lines are added. When new lines are being written on the log, the console will refresh them. We must use the interrupt key or “Ctrl+Z” to abort this command because the prompt does not return even after work is completed. In general, error messages are written to log files by the apps. An error message is checked by it when it appears in the log file.<\/p>\n
The below-mentioned command will print the last 10 lines of linux1.txt, but the file will not be closed; it will prompt to write data or press Ctrl+Z to exit.<\/p>\n
\n\n
\n \n $ tail -f linux1.txt<\/strong><\/pre>\n<\/th>\n<\/tr>\n<\/thead>\n<\/table>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2022\/02\/word-image-562.png\")
<\/p>\nHow to use the tail command with the -v option<\/strong><\/h3>\n
When this option is used, data from the chosen file is always followed by the name of the file.<\/p>\n
The below-mentioned command will print the last 10 lines of linux1.txt followed by the filename “linux1.txt”:<\/p>\n
\n\n
\n \n $ tail -v linux1.txt<\/strong><\/pre>\n<\/th>\n<\/tr>\n<\/thead>\n<\/table>\n

There are many ways to display data from a file; in this article, we discussed how we can view data with the help of the tail command.
