If a _.changes_ file is specified on the command line, the filename must end with _.changes_, as this is how the pro‐ gram distinguishes it from package names. If not, then **debi** has to be called from within the source code directory tree. In this case, it will look for the _.changes_ file corresponding to the current package version (by determining the name and version number from the changelog, and the architecture in the same way as [**dpkg-buildpackage**(1)](https://www.chedong.com/phpMan.php/man/dpkg-buildpackage/1/markdown) does). It then runs **debpkg** **-i** on every _.deb_ archive listed in the _.changes_ file to install them, assuming that all of the _.deb_ archives live in the same directory as the _.changes_ file. Note that you probably don't want to run this program on a _.changes_ file relating to a different architec‐ ture after cross-compiling the package! If a list of packages is given on the command line, then only those debs with names in this list of packages will be installed. Since installing a package requires root privileges, **debi** calls **debpkg** rather than **dpkg** di‐ rectly. Thus **debi** will only be useful if it is either being run as root or **debpkg** can be run as root. See [**debpkg**(1)](https://www.chedong.com/phpMan.php/man/debpkg/1/markdown) for more details. ### Directory name checking In common with several other scripts in the **devscripts** package, **debi** will climb the directory tree until it finds a _debian/changelog_ file. As a safeguard against stray files causing po‐ tential problems, it will examine the name of the parent directory once it finds the _de__‐ _bian/changelog_ file, and check that the directory name corresponds to the package name. Pre‐ cisely how it does this is controlled by two configuration file variables **DE**‐‐ **VSCRIPTS**___**CHECK**___**DIRNAME**___**LEVEL** and **DEVSCRIPTS**___**CHECK**___**DIRNAME**___**REGEX**, and their corresponding com‐ mand-line options **--check-dirname-level** and **--check-dirname-regex**. **DEVSCRIPTS**___**CHECK**___**DIRNAME**___**LEVEL** can take the following values: **0** Never check the directory name. **1** Only check the directory name if we have had to change directory in our search for _de__‐ _bian/changelog_. This is the default behaviour. **2** Always check the directory name. The directory name is checked by testing whether the current directory name (as determined by [**pwd**(1)](https://www.chedong.com/phpMan.php/man/pwd/1/markdown)) matches the regex given by the configuration file option **DE**‐‐ **VSCRIPTS**___**CHECK**___**DIRNAME**___**REGEX** or by the command line option **--check-dirname-regex** _regex_. Here _regex_ is a Perl regex (see [**perlre**(3perl)](https://www.chedong.com/phpMan.php/man/perlre/3perl/markdown)), which will be anchored at the beginning and the end. If _regex_ contains a '/', then it must match the full directory path. If not, then it must match the full directory name. If _regex_ contains the string ´PACKAGE', this will be re‐ placed by the source package name, as determined from the changelog. The default value for the regex is: ´PACKAGE(-.+)?', thus matching directory names such as PACKAGE and PACKAGE-ver‐ sion. ## OPTIONS ### -a -t See [**dpkg-architecture**(1)](https://www.chedong.com/phpMan.php/man/dpkg-architecture/1/markdown) for a description of these options. They affect the search for the _.changes_ file. They are provided to mimic the behaviour of **dpkg-buildpackage** when determining the name of the _.changes_ file. **--debs-dir** _directory_ Look for the _.changes_ and _.deb_ files in _directory_ instead of the parent of the source directory. This should either be an absolute path or relative to the top of the source directory. ### -m --multi Search for a multiarch _.changes_ file, as created by **dpkg-cross**. ### -u --upgrade Only upgrade packages already installed on the system, rather than installing all packages listed in the _.changes_ file. Useful for multi-binary packages when you don't want to have all the binaries installed at once. **--check-dirname-level** _N_ See the above section **Directory** **name** **checking** for an explanation of this option. **--check-dirname-regex** _regex_ See the above section **Directory** **name** **checking** for an explanation of this option. ### --with-depends Attempt to satisfy the _Depends_ of a package when installing it. **--tool** _tool_ Use the specified _tool_ for installing the dependencies of the package(s) to be in‐ stalled. By default, **apt-get** is used. **--no-conf**, **--noconf** Do not read any configuration files. This can only be used as the first option given on the command-line. **--help**, **--version** Show help message and version information respectively. ## CONFIGURATION VARIABLES The two configuration files _/etc/devscripts.conf_ and _~/.devscripts_ are sourced in that order to set configuration variables. Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The currently recognised variables are: **DEBRELEASE**___**DEBS**___**DIR** This specifies the directory in which to look for the _.changes_ and _.deb_ files, and is either an absolute path or relative to the top of the source tree. This corresponds to the **--debs-dir** command line option. This directive could be used, for example, if you always use **pbuilder** or **svn-buildpackage** to build your packages. Note that it also affects [**debrelease**(1)](https://www.chedong.com/phpMan.php/man/debrelease/1/markdown) in the same way, hence the strange name of the option. **DEVSCRIPTS**___**CHECK**___**DIRNAME**___**LEVEL**, **DEVSCRIPTS**___**CHECK**___**DIRNAME**___**REGEX** See the above section **Directory** **name** **checking** for an explanation of these variables. Note that these are package-wide configuration variables, and will therefore affect all **devscripts** scripts which check their value, as described in their respective man‐ pages and in [**devscripts.conf**(5)](https://www.chedong.com/phpMan.php/man/devscripts.conf/5/markdown). ## SEE ALSO [**debpkg**(1)](https://www.chedong.com/phpMan.php/man/debpkg/1/markdown), [**devscripts.conf**(5)](https://www.chedong.com/phpMan.php/man/devscripts.conf/5/markdown) ## AUTHOR **debi** was originally written by Christoph Lameter <>.
