[英]How do I convert a full path to a relative path using perl?
I have the full path to a file and the full path to one of its parent directories in two variables in Perl program. 我在Perl程序中的两个变量中具有文件的完整路径和其父目录之一的完整路径。
What is a safe way to calculate the relative path of the file relative to the parent directory. 什么是计算文件相对于父目录的相对路径的安全方法。 Needs to work on windows and unix.
需要在Windows和Unix上工作。
eg 例如
$filePath = "/full/path/to/my/file";
$parentPath = "/full";
$relativePath = ??? # should be "path/to/my/file"
Use File::Spec 使用文件:: Spec
They have a abs2rel function 它们具有abs2rel函数
my $relativePath = File::Spec->abs2rel ($filePath, $parentPath);
Will work on both Windows and Linux 在Windows和Linux上均可使用
use Path::Class;
my $full = file( "/full/path/to/my/file" );
my $relative = $full->relative( "/full" );
