如何使用 rex 創建目錄
rex
如果它不存在,我想創建一個目錄。我讀了這個 ,但我找不到怎麼做。如果我發送沒有目錄的文件,我會收到此錯誤:
ERROR - upload: /usr/local/path/file.ext is not writable
有什麼提示嗎?
我認為 rex 書中的文件有點舊。
請在此處查看https://www.rexify.org/docs/api/或(截至今天)此處的最新文件:

(它說的是版本 1.4,而目前的 cpan 版本是 1.6,但沒關係)所以,用一個例子來回答你的問題:
task "backuptask", group => "mygroup", sub { # # 1.) define the Backup Dir (you could do it without this step) my $backupdir = "/tmp/backup"; # # 2.) "ensure" that the file is a (existing) "directory" file $backupdir, ensure=> "directory", owner => "myowner", group => "mygroup", mode => 700, on_change => sub { say "File was changed";}; # # 3.) define Backup File my $currTimestamp = strftime('%y%m%d',localtime); my $backupfile = "$backupdir/somebackup$currTimestamp"; # # 4.) "ensure" the the file is "present" at the defined path file $backupfile, ensure=> "present"; ...execute something here... } ;
