如何用awk删除一个文本中某行的第n列

02-CPU 1 | 04h | ok | 65.1 | 41 degrees C
03-CPU 2 | 05h | ok | 65.2 | 40 degrees C
04-P1 DIMM 1-6 | 06h | ns | 32.1 | Disabled
05-P1 DIMM 7-12 | 07h | ok | 32.2 | 39 degrees C
我需要删除四五（DIMM所在）行的第三列，然后显示
02-CPU 1 | 04h | ok | 65.1 | 41 degrees C
03-CPU 2 | 05h | ok | 65.2 | 40 degrees C
04-P1 DIMM | 06h | ns | 32.1 | Disabled
05-P1 DIMM | 07h | ok | 32.2 | 39 degrees C

Answer 1

awk '{if(NR==n) $n=新数据;print $0}'
上面命令中n为行数和列数
