问题 How does one create a report file where a DEL command failed to execute properly? I would have thought you'd do: DEL FILENAME.TXT ECHO "FILENAME.TXT" >> REPORT.TXT but all it does is make an empty report file, regardless of if it finds FILENAME.TXT or not. I'm wanting to create a report file where if it failed to delete FILENAME.TXT for whatever reason that the message that pops up is dumped into REPORT.TXT. Any ideas? 回答1: The Del command always returns errorcode 0 even if file is not found

问题 Using the windows api, is there any way to delete a large file (lets say 1gb+), and monitor the progress somehow? I'm sure its possible but I have no idea where to start.. EDIT: Should have been more specific, I want to move the file to the recycle bin, and show a progress bar similar to explores, though I might want the progress bar in a console or something so I don't want an exact replica. EDIT 2: Yeaah guess it is instant, should have tested before I asked the question. Anyway to just

问题 I have two directories, let's call them src and build . My build system works so that for all files with mtime more recent in src than in build it copies the file from src to buid and does some transformations (minification, versioning, etc.). Otherwise skips as the file is considered up to date. This however poses a problem when source file is deleted, as its built version is still present in build and gets into map file generated afterwards. $ ls src example1.js example2.js $ ant do-the

问题 I have the following delete task added to my build.gradle file: task cleanExtra(type: Delete) { delete '../version.properties' } clean.dependsOn(cleanExtra) Sometimes, when I call gradle clean , it will fail with "Unable to delete file: (...)/version.properties". But if I call the same clean task a second time, it will successfully delete the task. Why does this happen? Anyway to avoid it? 回答1: It sounds like JIRA issue Gradle-2244 : Unable to delete file/directory, and then a subsequent

问题 There is a folder in a Google Storage bucket. I need to delete (with JSON API) the folder (let denote it xxx/ ) if and only if it is empty. The most obvious way is to check if it is empty and delete if it is empty. This requires an additional request and also may be subject to race conditions. However, what about deleting the xxx/ object unconditionally? If it is empty deleting will do what we need, and if it is nonempty xxx/ will continue to behave like a folder because there are files with
