melt

QNX SDP8.0Utilities ReferenceUtilities

Uncompress frozen files (UNIX)

Syntax:

melt [-cfvVz] [filename...]

Runs on:

QNX OS

Options:

See freeze.

Description:

The melt utility is equivalent to freeze -d. See the freeze utility for details.

Note:

The freeze, melt, and fcat compression utilities will eventually become deprecated in favor of toybox utilities, which include, gzip, gunzip, and zcat. The freeze suite of utilities will continue to be provided for quite some time before being eliminated completely.
