NAME

apt-file-from-installed -- create apt-file contents from installed packages

SYNOPSIS

 apt-file-from-installed [--verbose] [--version]

DESCRIPTION

apt-file-from-installed creates a contents file as used by apt-file, built from the currently installed packages instead of downloading. For example if your sources.list had ftp.debian.org the file might be

    /var/cache/apt/apt-file/ftp.debian.org_debian_dists_unstable_main_Contents-i386.gz

The contents created is not a full list of files, only what you have installed. But it's faster than downloading and it includes any packages installed locally and not through an actual private repository (important for dh-make-perl).

New contents are written first to a temporary file in /var/cache/apt/apt-file/ and only moved to the real name when complete. This is atomic so users running apt-file see the new contents file only when it's complete.

Other Notes

Currently the last sources.list entry is used as the target, and any other contents files are removed. Perhaps that should be configurable.

Only gzip -1 level compression is used for the contents file, so that it's faster to update if you do so repeatedly after installing new things. That compression level already takes the file to about 1/4 of original size.

FILES

/var/cache/apt/apt-file/ -- contents files directory.

/var/cache/apt/apt-file/*.apt-file-from-installed.* -- temporary files.

/etc/apt/apt-file.conf -- the apt-file configs (determining the contents directory and filename format)
