This article mainly introduces "how to use the linux command to output a specific line of the file". In the daily operation, I believe that many people have doubts about how to use the linux command to output the specific line of the file. The editor consulted all kinds of data and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "how to use the linux command to output the specific line of the file". Next, please follow the editor to study!

You usually use the sed command to print a specific line, such as

#-n: print in a specific format

# 100p: refers to printing the 100th line

$sed-n 100p Readme.md

But sed's ability to print is much more than that. In addition to printing specific lines, you can also print a range of lines, such as

# Line 100-120 in the print file

$sed-n 100120p Readme.md

# Line 100-120 in the print file

$sed-n 100cm 20p Readme.md

There is also a way to combine head/tail commands to output the 100th behavior example

# output the first 100 lines, then output the last line through pipe

$head-100Readme.md | tail-1

For more information about the use of sed, please refer to my article: detailed explanation of sed command and examples.
