APT for Debian maintenance tools

Debian maintenance tool APT-Linux Release Technology-Debian information. The following is a detailed description. 1. A Tool for automatically configuring resource lists is provided in the basic system: apt-setup. The tool is provided by base-config (currently only available in sarge ).

# Base-config

Call or directly run

# Apt-setup

2 apt-spy mode:
Apt-spy tests the list, finds the fastest one based on the bandwidth and response speed, and automatically saves the result to/ect/apt/sources. list.

# Apt-get install apt-spy

# Mv sources. list sources. list. bak // backup

# Man apt-spy // obtain detailed usage

# Apt-spy update // update your image list file/var/lib/apt-spy/mirrors.txt
You can restrict the test to a country or region, and provide the option to limit the number of test servers. also, zones can be defined in the/etc/apt-spy.conf. you can use the following command to find the fastest image in Asia and generate a record for testing:

# Apt-spy-d testing-a Asia

3 common apt commands

Apt-get dist-upgrade // system upgrade
Apt-cache search packages // search software package
Apt-cache show packages // obtain the related information of the software package.
Apt-cache depends packages // query the packages associated with the package
Apt-cache rdepends packages // query which packages are associated with this package
Apt-cache showsrc packagename | grep Build-Depends // view the compilation of a software? Apt-cache policy packagename // check the package status
Apt-get install -- print-uris packages // -- print-uris option to output the information to the screen
Apt-get install packages-s (-- simulate) // just simulate it, instead of installing it

4. Advanced Query
If you want to install a software package, but you cannot find its name using apt-cache, but you know the program file name or the file name of some files in the software package, you can use apt-file to find the package name. this tool is provided by software packages with the same name. apt-file is actually a Contents file interface provided in the APT software library. each release provides such a file, including a list of all files to be installed in a release. before using apt-file, you must first obtain the Contents file to be queried. run apt-file update to download the file to the/var/cache/apt directory. in this way, you can use apt-file to query this file. apt-file is mainly used to determine which software package provides a file.

Apt-file search filename

With this command, you can list the content of the software package:

Apt-file list packagename

Like apt-get, this database also needs to be updated in real time, and can be run after the update is completed:

Apt-file update
