[root@localhost INCR_1]# qpress -v qpress 1.1 - Copyright 2006-2010 Lasse Reinhold - www.quicklz.com Using QuickLZ 1.4.1 compression library Compiled for: Windows [*nix] [x86/x64] RISC 32-bit [64-bit] Compression: qpress [-rovfCBPLKT] <source file/dir search pattern> <destination file> qpress -i[ovfBPLKT] <filename to give stdin data> <destination file> Decompression: qpress -d[ovfBPTn] <source file> <destination directory> Benchmark and recovery: qpress -m[LT] <source file> qpress -R <corrupted compressed file> <destination directory> Flags: -d Decompress -Ln Set compression level to n where n = 1, 2 or 3 (default = 1) -r Include sub directories during compression -v Show progress information during compression and decompression -i Read from stdin (omit source file or file/dir search pattern) -o Write to stdout (omit destination file or directory) -f Overwrite existing files during compression and decompression (default is to abort) -C Continue if a source file cannot be opened during compression (default is to abort) -Tn Use n threads/cores where n = 1 to 256 (default = 2). Be aware of memory usage with large n -Kn Read from disk in n KiB chunks during compression where n = 64 to 32768 (default = 64). Be aware of memory usage with large n -B Windows only: Disable file system caching (FILE_FLAG_NO_BUFFERING) to prevent cache of other applications from being be flushed. Keep enabled if files are small and need further processing -Pn Windows only: Set CPU and disk I/O priority to n where 1 = BACKGORUND (Vista, 7, 2008 only), 2 = IDLE, 3 = NORMAL or 4 = ABOVE (default = 3) Examples of compression: qpress -v file1.xml file2.xml file3.xml database.qp qpress -vfK4096T2 *.xml database.qp 2> log.txt qpress -ovL3K *.xml > database.qp cat database.xml | qpress -i database.xml database.qp cat database.xml | qpress -io database.xml > database.qp Examples of decompression: qpress -d database.qp ./dir qpress -do database.qp > database.xml cat database.qp | qpress -di . Notes: When compressing on *nix with -r flag, file/dir search pattern only filters in top level directory (directories matching in top level will be included fully). If a compressed file contains multiple files and is decompressed to stdout, all files will be concatenated in a continuous stream. It's recommended to use .qp as filename suffix.
