awk - AWK: How to remove a column deliminated by mixed delimeters?

Question

I have a table with 100,000 rows. The format is like this:

abc '\t' gi| a b c  d e

column abc is separated by tab while other columns are separated by space.I want to remove the column 'gi|' and keep all other columns. I tried use tab or | as my delimiter but it didn't work well. Any thoughts?

Answer 1

你可以使用awk的sub功能。

awk '{sub(/.*/,"",$2)}1' file

或者

只需为第 2 列变量分配一个空值。

awk '{$2=""}1' file

Answer 2

为什么不简单地忽略这些字段？

sed 's/\t[^\t ]* /\t/' file

将删除第一个制表符后的文本到空格。
