NAME

defrag - Defrag files

SYNOPSIS

defrag [OPTION]... FILE...

DESCRIPTION

defrag defrags files simply by making a copy of the file, and then replacing the original file with the copy.

Due to the fact that BitTorrent splits files in pieces, and downloads these pieces in random order, the downloaded files are often severely fragmented. This means that reading these files will be slower, sometimes as much as 30% slower. defrag can also recurse directories when the `-r' option is given.

Note that newer versions of the official BitTorrent client does not allocate file contents in advance. It will instead write pieces in the order they were downloaded, and reorder them later. This makes defrag unnecessary for files downloaded with this client. (However, defrag might still be useful as a file defragmentation tool.)

OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.
-v, --verbose
Explain more in detail what is being done. This option makes defrag print the name of each file prior to defragging it.
-r, --recrusive
Travel directories, defragging each file in the directory, its subdirectories and so on.
--help
Show summary of options.
--version
Output version information and exit.

EXAMPLES

Defrag all files in the directory `downloads' recursively, and print the name of each file defragged:
       defrag -r -v downloads
