sqfscat 命令

常用示例

说明

sqfscat outputs the contents of files from a squashfs filesystem to stdout, similar to how cat works on regular filesystems. Squashfs is a highly compressed read-only filesystem supporting gzip, xz, lzo, lz4, zstd, and lzma compression. The tool allows extracting file contents without mounting the filesystem, useful for inspection, scripting, and embedded systems. Multiple files can be specified and their contents will be concatenated.
