我有2个制表符分隔的文件格式与此类似:
档案1
A 100 90 PASS
B 89 80 PASS
C 79 70 PASS
D 69 60 FAIL
F 59 0 FAIL
文件2
Randy 80
Denis 44
Earl 97
我想从文件2中的第2列获取值,并将它们与文件1的第2列和第3列之间给出的范围进行比较。然后我想创建一个组合此数据的新文件,从第1列和第2列打印文件2和文件1中的第1列和第4列:
文件3
Randy 80 B PASS
Denis 44 F FAIL
Earl 97 A PASS
我想用awk或perl实现这个。
答案 0 :(得分:3)
你可以使用这个awk:
awk 'BEGIN{FS=OFS="\t"}
FNR==NR {
a[$0] = $2
next
}
{
for (i in a)
if ($2>=a[i] && $3<=a[i])
print i, $1, $4
}' file2 file1

答案 1 :(得分:2)
在perl中,我可能会做这样的事情:
#!/usr/bin/env perl
use strict;
use warnings 'all';
use Data::Dumper;
open ( my $grades_in, '<', "file1.txt" ) or die $!;
my @grade_lookup = map { [split] } <$grades_in>;
print Dumper \@grade_lookup;
close ( $grades_in );
open ( my $people, '<', "file2.txt" ) or die $!;
while (<$people>) {
chomp;
my ( $person, $score ) = split;
my ( $grade ) = grep { $_ -> [1] >= $score
and $_ -> [2] <= $score } @grade_lookup;
print join " ", $person, $score, $grade -> [0], $grade -> [3], "\n";
}
close ( $people );

答案 2 :(得分:2)
在Perl中
use strict;
use warnings 'all';
use autodie;
use List::Util 'first';
my @grades = do {
open my $fh, '<', 'file1.txt';
map [ split ], <$fh>;
};
open my $fh, '<', 'file2.txt';
while ( <$fh>) {
my ($name, $score) = split;
my $grade = first { $_->[2] <= $score } @grades;
print "$name $score @$grade[0,3]\n";
}
