How to display a file from one line number to another in Linux

If you need to read a file and print from a range of line numbers (including the last one), you can use the command as shown below.

cat <filename> | awk 'NR >=linenumber1 && NR <=linenumber2'

To read and display a file along with the line numbers, you can use the following format:.

cat -n <filename>

Example:

cat -n sample.txt

display line number
For example:

To print lines starting from line 2 to line 7, then you can use the following command.

cat sample.txt | awk 'NR >=2 && NR <=7'

Sample Output:

use cat and awk to print range of line numbers in linux
If for any reason you need to display the line numbers along with the output, then you can pass the -n argument to cat before piping it to awk as shown below.

cat -n sample.txt | awk 'NR >=2 && NR <=7'

Sample Output:

print with line numbers

[Note: There are multiple methods to do the same procedure. This method is intended for beginners who are just getting started in Linux.]
