deflate

Runs on:

QNX Neutrino, Linux, Mac, Microsoft Windows

Options:

-b size

The compression block size; one of 4 KB, 8 KB, 16 KB, or 32 KB (default: 8 KB). The K is assumed; you don't need to specify it.

-d

Decompress (the same as -i so it can be used as a filter by tar).

-i

Inflate files (default: deflate).

-o fname

The output filename. A filename of - means standard output. By default, deflate compresses the files in place.

-t 1|2

The compression type; the default is 2. For a comparison of the types, see below.

-v

Be verbose; list information on each file as it's compressed.

filename...

The files to compress. If no files are given and the -i option is specified, deflate reads from standard input and writes to standard output, allowing it to be used as a filter.

Description:

The deflate utility compresses files for a flash filesystem. It's intended to be used in conjunction with the filter attribute for mkefs. It can also be used to precompress files intended for a flash filesystem.

The compression types (specified with the -t option) are:

Examples:

Deflate all executables that are to be placed on an embedded target:

deflate -v /target/bin/* /target/lib/*

Inflate a previously deflated file:

deflate -i deflated_file

Deflate a file without changing the input file:

deflate -o file.dfl file
