如果我已经在子目录中,我想知道如何搜索子文件夹。
例如:..build/clean/test/子文件夹<-----
我已经编写了如何进行测试的脚本,但不知道如何进入子文件夹。
脚本看起来像这样: Perl 中的目录句柄无法正常工作
sub response {
foreach my $arg (@ARGV) {
print "Investigating $arg directory below:-\n";
opendir(my $DIR, $arg) or die "You've Passed Invalid Directory as Arguments\n";
my $size = 0;
while(my $fileName = readdir $DIR) {
next if $fileName =~ /^\./;
my $path = File::Spec->catfile( $arg, $fileName );
if( -d $path) {
say "Folder1($arg, $fileName)"
}
$size++;
}
closedir $DIR;
if($size == 0) {
print "The $arg is an empty directory\n";
}
}
这是子文件夹
sub Folder1
{
my $prevPath = shift;
my $receivedFolder = shift;
my $realPath = "$prevPath/$receivedFolder";
my $path = File::Spec->rel2abs($realPath);
print "$path\n";
print "$receivedFolder Folder Received\n";
foreach my $folder (@folder)
{
opendir(DIR, $path) or die "You've Passed Invalid Directory as Arguments\n";
while(my $file = readdir $DIR) {
next if $file =~ /^\./;
my $path1 = File::Spec->catfile( $folder, $file );
if( -d $path1) {
say "Folder2($folder2, $file)"
}
closedir(DIR);
}
子2文件夹
sub Folder2 {
my $prevPath1 = shift;
my $receivedFolder1 = shift;
my $realPath1 = "$prevPath1/$receivedFolder1";
my $path1 = File::Spec->rel2abs($realPath1);
print "$path1\n";
print "$receivedFolder1 Folder Received\n";
opendir(DIR, $path1) or die "You've Passed Invalid Directory as Arguments\n";
while(my $file = readdir DIR) {
print "Current Folder has $file file\n";
}
closedir(DIR)
}
我想读取 sub 2 文件夹内的文件。但是,我一直使用 sub 2 文件夹返回主目录。
my @arg = ('clean');
my @folder = ('logs');
但是,在构建目录中还有一个日志文件夹。它将被重定向到那里而不是 ../clean/test/logs
对于使用路径,我强烈推荐Path::Tiny。
use Path::Tiny 'path';
my $path = path "/home/tai/Documents/";
for my $child ( $path->children ) {
print "$child\n" if $child->is_file;
}
my $parent = $path->parent;
print "PARENT: $parent\n";
也许下面的代码片段可以阐明解决问题的可能方法。
use strict;
use warnings;
use feature 'say';
my $dir = '.';
folder_dive($dir);
sub folder_dive {
my $folder = shift;
say "In folder: $folder";
for ( glob("$folder/*") ) {
say "directory $_" if -d; # if we got a directory
say "file $_" if -f; # if we got a file
say "\ta file" if -f;
say "\ta link" if -l;
say "\ta socket" if -S;
say "\ta pipe" if -p;
say "\ta block device" if -b;
say "\ta char device" if -c;
say "\ta text" if -T;
say "\ta binary" if -B;
say "\treadable" if -r;
say "\twritable" if -w;
say "\texecutable" if -x;
say "\towned by user" if -o;
say "\treadable by real user" if -R;
say "\twritable by real user" if -W;
say "\texecutable by real user" if -X;
say "\towned by real user" if -O;
say "\tzero size" if -z;
say "\tnonzero size" if -s;
say "\tsetuid" if -u;
say "\tsetguid" if -g;
say "\tsticky bit set" if -k;
say "\tisatty is true" if -t;
folder_dive("$_") if -d; # if we got a directory
}
}
