我有一个 Perl 脚本,它读取文件并搜索 3 个可能字符串中的 1 个。
当它找到具有匹配字符串的行时,它会在空格上分割该行,选择结果数组中的一个元素,然后用 + 将该行重新连接在一起,并将该行添加到哈希中。
数据结构如下:
问题是额外的条目被添加到具有无效键的哈希中。我已经剥离了
\r
的输入,并将捕获的行写入文件,然后再将其添加到哈希中。我不明白为什么会发生这种情况。
这是代码:
sub ProcessInput() {
my $word;
foreach $word (@wantLines) {
if ($DEBUG) { print( $word, ":\t", $line, "\n" ); }
if ( $line =~ /$word/ ) {
if ( $word eq "C3_TIMEOUT_FRAME"
|| $word eq "RX_WT_AVG_B2B_ZERO"
|| $word eq "TX_WT_AVG_B2B_ZERO" )
{
if ($DEBUG) { print $word, "\n"; }
# store the counter in the hash
# the key is the entire line where spaces are replaced with '*'
# this is the only way to guarantee a unique key
print "Captured Line is $line\n";
my @values = split( " ", $line );
my $key = join( '*', @values );
my $epoch = parsedate( $values[3] ); #, GMT=>1);
open( FILE, ">$outfile" ) || die "Can't open file ($!)\n";
# unless (exists $hash{$epoch}->{$key})
unless ( exists $hash{$key} ) {
# print "Added key $key to the hash\n";
$hash{$epoch}->{$key} = $line;
# add the entry to the hash, but only if it doesn't exist already
# the value is the date for the log entry
# unless (exists $hash{$key})
$hash{$key} = $values[3];
} #unless
} #if $word
} #if $DEBUG
} #foreach
这是一些输入。我加星标的行是无效哈希条目之前的最后一行,但完整输出中还有更多行。

这是哈希值,包括无效条目 - 无效条目是最后一个条目。
