使用awk过滤文本文件中的行

Question

I have tab delimited text file (like this):

A  1 A1g DELL
A  1 B1s HP
A  7 Zfd Nog
A  5 Jgf KIT
A  1 Def JOP

Apart from the first row, I would like to keep only the rows where the second column's value is larger than 1.

A  1 A1g DELL
A  7 Zfd Nog
A  5 Jgf KIT

I tried awk '{if($2>1) print }' file.txt but it omits the first row. How can I skip the first row and check the condition ($2 >1) for other rows?

Thanks in advance.

Answer 1

In AWK:

$ awk 'NR==1||$2>1' test.in
A  1 A1g DELL
A  7 Zfd Nog
A  5 Jgf KIT
