I am using boost::filesystem to loop over files in a directory and conditionally delete them. It works in boost 1.71 but in boost 1.74 it crashes after the first file has been deleted. Is this a bug or am I doing something wrong? What is the recommended way to iterate over a directory and delete files?$ git clone cd boost-filesystem-bug$ docker build -t focal -f focal.Dockerfile .$ docker build -t jammy -f jammy.Dockerfile .# boost 1.71, files deleted$ docker run -it focal /test-boost/a.out"/tmp/b"filesystem::recursive_directory_iterator directory error: No such file or directory"/tmp/a"filesystem::recursive_directory_iterator directory error: No such file or directory"/tmp/c"filesystem::recursive_directory_iterator directory error: No such file or directory# boost 1.74, first file deleted, then crashes$ docker run -it jammy /test-boost/a.out"/tmp/b"filesystem::recursive_directory_iterator increment error: No such file or directorya.out: /usr/include/boost/filesystem/directory.hpp:534: void boost::filesystem::recursive_directory_iterator::disable_recursion_pending(bool): Assertion `(!is_end())&&("disable_recursion_pending() on end recursive_directory_iterator")' failed.main.cpp:#include int main() { boost::filesystem::path path("/tmp"); boost::filesystem::recursive_directory_iterator it(path), ite; while(it != ite) { if (!boost::filesystem::is_directory(*it)) { std::cout path() path()); } try { ++it; } catch(std::exception& e) { std::cout #include #include int main() { boost::filesystem::path path("/tmp"); boost::filesystem::recursive_directory_iterator it(path), ite; while(it != ite) { if (!boost::filesystem::is_directory(*it)) { std::cout path() path()); } try { ++it; } catch(std::exception& e) { std::cout

We need to create and build a file system before using any data storage device connected to a Linux machine. The mkfs command examples show you how to usemkfs properly to create a filesystem in Linux.NAME: mkfs – build a Linux file system.SYNOPSISmkfs [options] [-t type] [fs-options] device [size]DESCRIPTIONThis mkfs frontend is deprecated in favour of filesystem-specific mkfs. utils.mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g. /dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the filesystem.The exit code returned by mkfs is 0 on success and 1 on failure.In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific builder is searched for via your PATH environment setting only. Please see the filesystem-specific builder manual pages for further details.OPTIONS-t, --type typeSpecify the type of filesystem to be built. If not specified, the default filesystem type (currently ext2) is used.fs-optionsFilesystem-specific options to be passed to the real filesystem builder.-V, --verboseProduce verbose output, including all filesystem-specific commands that are executed. Specifying this option more than once inhibits execution of any filesystem-specific commands. This is really only useful for testing.-V, --versionDisplay version information and exit. (Option -V will display version information only when it is the only parameter, otherwise it will work as --verbose.)-h, --helpDisplay help text and exit. AVAILABILITY: The mkfs command is part of the util-linux package and is available from Command Examplesmkfs -t ext3 /dev/sda1The above example would create an ext3 file system on a hard disk.If we just type mkfs and pressing the tab key twice, we’ll see a list of all the different commands.mkfs command line examples in LinuxFind

Have you ever needed to transfer some files from your Linux computer to a Windows PC? Or wanted to back up your important documents from your shiny new Linux laptop to an external hard drive?Chances are you reached for a trusty USB flash drive. Those convenient plug-and-play storage devices make sharing files across different operating systems a breeze.But what if you just got a brand new USB drive? Before you can start copying files, music, or backups, you‘ll need to format it with a filesystem.Formatting a drive erases any existing data and prepares it for use with your operating system of choice.Most flash drives come pre-formatted with the FAT32 filesystem. This offers back compatibility with older versions of Windows.But you may want to reformat your drive, especially if you plan on using it with Linux. This guide will walk you through everything you need to know to format a USB drive on Linux, including:What is a filesystem and why does it matter?When should you use FAT32 vs other filesystem formats? Step-by-step instructions for formatting drives on LinuxFormatting via command line and GUI methodsAdditional tips for maintaining your USB storageReady to learn how to wield the full power of Linux for your USB storage needs? Let‘s dive in.What is a Filesystem and Why Does it Matter?Before we actually reformat a drive, it helps to understand what exactly a "filesystem" is and why it is so important.A filesystem defines how data is stored and retrieved from a storage device. It provides structure to the raw storage, allowing information to be saved, retrieved, accessed, and organized in a meaningful way.Some common filesystem examples you may have heard of:FAT32 – Compatible across operating systems. Limited 4GB file size.NTFS – Default modern Windows filesystem. Offers advanced features. HFS+ – Default on modern macOS devices. Journaled for data integrity.ext4 – Common Linux filesystem. Great performance, stability, and tools.When you format a USB drive, you are defining the structure of that drive by selecting a filesystem. This includes creating a partition table that segments the raw storage into smaller logical sections.Within the partition, the filesystem organizes files and folders, tracks used/free space, and stores file metadata (permissions, size, etc).Why does the filesystem matter so much for USB drives? Because you want maximum compatibility with all devices you might plug that drive into.For example, using ext4 or other Linux-native filesystems will provide high performance and advanced features.
