# 7Zip
7-Zip is a file archiver with the highest compression ratio. The program supports 7z (that implements LZMA compression algorithm), [ZIP](../../../files/ZIP.md), CAB, ARJ, GZIP, BZIP2, [TAR](compression/tar.md), CPIO, RPM and DEB formats. Compression ratio in the new 7z format is 30-50% better than ratio in [ZIP](../../../files/ZIP.md) format.

# SSH
Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Typical applications include remote command-line login and remote command execution, but any network service can be secured with SSH.
Examples of services that can use SSH are [Git](../../dev/Git.md), [rsync](rsync.md) and X11 forwarding. Services that always use SSH are SCP and SFTP.

An SSH server, by default, listens on the standard [TCP](../../internet/TCP.md) port 22. An SSH client program is typically used for establishing connections to an sshd daemon accepting remote connections. Both are commonly present on most modern operating systems, including [macOS](../../macos/macOS.md), GNU/[Linux](../../linux/Linux.md), Solaris and OpenVMS. Proprietary, freeware and open source versions of various levels of complexity and completeness exist.

- `install` : There are 6 different types of install scripts. Install scripts are named `$pkgname.action`, where action can be: `pre-install`, `post-install`, `pre-upgrade`, `post-upgrade`, `pre-deinstall`, or `post-deinstall`. For example, if `pkgname` is set to mypackage and install is set to `$pkgname.post-install`, then a script named `mypackage.post-install` must exist along-side the APKBUILD.
- `$pkgname.pre-install` : This script is executed before installing the package. Typical use is when the package needs a group and a user to be created.
- `$pkgname.post-install` : This script is executed after installing the package.
- `$pkgname.pre-upgrade` : This script is executed before upgrading/downgrading/reinstalling the package. Note that exiting with failure will not cause [apk](alpine/apk.md) to exit with failure, but will mark the package as broken.

- `pkgname` : The name of the package. All letters should be lowercase.

- `pkgver` : The version of the software being packaged. Format for valid versions: `{digit}{.digit}...{letter}{_suf{#}}...{-r#}`. A Suffix suf in the above format can be one of the following to indicate that the release is less recent than the version without the suffix: `alpha`, `beta`, `pre`, `rc`. These are for indicating more recent releases: `cvs`, `svn`, `git`, `hg`, `p`. All other suffices are invalid. To package a specific [git](../../../dev/Git.md) commit, the date of the commit gets appended to the latest release, e.g. `1.0.0_git20180204`.
- `provides` : List of package names (and optionally version info) this package provides. If package with a version is provided (provides='foo=1.2') [apk](alpine/apk.md) will consider it as an alternate name and it will automatically consider the package for installation by the alternate name, and conflict with other packages having the same name, or provides. If version is not provided (provides='foo'), [apk](alpine/apk.md) will consider it as virtual package name. Several package with same non-versioned provides can be installed simultaneously. However, none of them will be installed by default when requested by the virtual name - instead, error message is given and user is asked to choose which package providing the virtual name should be installed.

However, none of them will be installed by default when requested by the virtual name - instead, error message is given and user is asked to choose which package providing the virtual name should be installed.
- `provider_priority` : A numeric value which is used by apk-tools to break ties when choosing a virtual package to satisfy a dependency. Higher values have higher priority. The primary use case is to specify the primary package that satisfies a virtual (provider).
- `replaces` : Allow this package to be installed at the same time as the listed packages, even if they have conflicting files. The files from this package will override ("take over") the conflicting files. This can be used to override config files with "policy packages".Another use case is renaming packages (or moving files from one package to another): "replaces" will avoid the file conflict error that [apk](alpine/apk.md) reports if it happens to install the new package before uninstalling the old package. A common misconception is that "replaces" is used to replace packages (like in [PKGBUILD](../arch-linux/PKGBUILD.md)). This is not the case, it is only for solving file conflicts.

Examples of such local files include: init.d files, conf.d files, install files (see install variable), patches, and all other necessary files.
- `triggers` : Apk-tools can "monitor" directories and execute a trigger if any package installed/uninstalled any file in the monitored dir. The triggers are always executed after the [apk](alpine/apk.md) action (install, uninstall, upgrade). The triggers are specified in the format: `scriptname=pathlist` where scriptname is the (sub)package name + `.trigger` suffix and pathlist is `:` separated list of the dirs to monitor. The triggers variable must include the triggers for subpackages too if they have any. It is possible to use wildcards (`*`) in the dir list.
