# Installation scripts order
|
||||
|
||||
Execution order of installation scripts (`preInstallScript, preRemoveScript, postInstallScript, postRemoveScript`) is different for DEB and RPM packages.
|
||||
**NOTE!** 'remove' scripts is using from old version!
|
||||
|
||||
## DEB scripts order
|
||||
|
||||
Useful link: https://wiki.debian.org/MaintainerScripts
|
||||
```
|
||||
DEB (apt) Install v2.2.2:
|
||||
[*] Before install (2.2.2 : deb : install)
|
||||
[*] After install (2.2.2 : deb : configure)
|
||||
|
||||
DEB (apt) Upgrade v1.1.1 -> v2.2.2:
|
||||
[*] Before remove (1.1.1 : deb : upgrade)
|
||||
[*] Before install (2.2.2 : deb : upgrade)
|
||||
[*] After remove (1.1.1 : deb : upgrade)
|
||||
[*] After install (2.2.2 : deb : configure)
|
||||
|
||||
DEB (apt) Remove:
|
||||
[*] Before remove (1.1.1 : deb : remove)
|
||||
[*] After remove (1.1.1 : deb : remove)
|
||||
```
|
||||
|
||||
## RPM scripts order
|
||||
|
||||
Useful link: https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/
|
||||
|
||||
When scriptlets are called, they will be supplied with an argument.
|
||||
This argument, accessed via $1 (for shell scripts) is the number of packages of this name
|
||||
which will be left on the system when the action completes.
|
||||
|
||||
```
|
||||
RPM (dnf) install:
|
||||
[*] Before install (2.2.2 : rpm : 1)
|
||||
[*] After install (2.2.2 : rpm : 1)
|
||||
|
||||
RPM (dnf) upgrade:
|
||||
[*] Before install (2.2.2 : rpm : 2)
|
||||
[*] After install (2.2.2 : rpm : 2)
|
||||
[*] Before remove (1.1.1 : rpm : 1)
|
||||
[*] After remove (1.1.1 : rpm : 1)
|
||||
|
||||
RPM (dnf) remove:
|
||||
[*] Before remove (2.2.2 : rpm : 0)
|
||||
[*] After remove (2.2.2 : rpm : 0)
|
||||
```
