我在名为ff的文件夹中有一些文本文件，如下所示。我需要根据另一个文件 aa.txt 删除这些文件中的行。

aa.txt文件：
32bm B 143 145
2fok X 361 363
2moj B 361 367

例如，在 32bm.txt 中，我只需要有B（column3）的行和143到145（column2）的数字。
期望的输出：

答案 0 :(得分：2)
使用awk你会做这样的事情：
#!/usr/bin/awk -f
NR == FNR { # If we are in the first file
low[$1,$2]=$3 # store the low value in a map
hi[$1,$2]=$4 # store the high value in another map
next # skip the remaining commands
}
# We are not in the first file
($2 >= low[FILENAME,$3]) && ($2 <= hi[FILENAME,$3])
# The FILENAME variable holds the name of the current file
# If the number we read is within the range, do the
# default action (which is to print the current line
将脚本放在名为script.awk的文件中，并按以下方式运行：
$ ./script.awk aa.txt 32bm 2fok

或者如果您更喜欢一个班轮：
awk 'NR==FNR{low[$1,$2]=$3;hi[$1,$2]=$4;next}$2>=low[FILENAME,$3]&&$2<=hi[FILENAME,$3]' aa.txt 32bm 2fok
