请问这两个linux ,大哥 大姐
awk -F ,'{if ($1!/\./) print $1","$3}' 和 awk -F"," 'NR==FNR{a[$2]=$0;next}{sub($1,a[$1]请问这两个linux ,大哥 大姐
这两个是awk语句
awk -F , '{if ($1!~/\./) print $1","$3}'
以,(逗号为分隔符)如果第一列不匹配.(点)则打印第一列和第三列数据.
awk -F"," 'NR==FNR{a[$2]=$0;next}{sub($1,a[$1]
第二个不全 ,看开头.应该是第一个文件的内容存入顺组的第二列,第二个文件的第一列存入数组的第一列.不全,只能大概看懂这个意思.
