獲取匹配特定模式的前n行（使用Linux命令）

Question

我有一個巨大的文件，我想找到一個術語模型。我想將包含單詞模型的前5行傳送到另一個文件。我該如何使用Linux命令來做到這一點？

Answer 1

man grep提到

-m NUM, --max-count=NUM 
      Stop reading a file after NUM matching lines. If the input is 
      standard input from a regular file, and NUM matching lines are 
      output, grep ensures that the standard input is positioned to 
      just after the last matching line before exiting, regardless of 
      the presence of trailing context lines. This enables a calling 
      process to resume a search. 

因此可以使用

grep model old_file_name.txt -m 5 > new_file_name.txt 

無需管道。 grep支持你自己需要的幾乎所有東西。

Answer 2

grep「model」filename |頭-n 5> newfile中

Answer 3

grep model [file] | head -n 5 > [newfile] 

Answer 4

cat file | grep model | head -n 5 > outfile.txt
