sqfscat

sqfscat is a command line tool used for concatenating multiple SQFS (Squash File System) files. SQFS is a compressed read-only file system commonly used in embedded systems and Linux distributions. The primary purpose of sqfscat is to merge multiple SQFS files into a single SQFS file, allowing users to combine the contents of different file systems or squashfs images. This tool is useful in scenarios where separate file systems need to be merged, such as creating a single file system for distribution or combining root file systems for booting. sqfscat works by reading the input SQFS files and appending their contents to create a final output file. It can concatenate files with different compression algorithms and handles file system-specific metadata. The resulting merged SQFS file can be used like any other squashed file system image.
