CASHAC on Linux


Cashac on Linux is “Cashac3”.
(“Cashac2” was Windows/Firebird, “Cashac” was Windows/Paradox).

The current version of Cashac3 is 42 (February 2026). Download it by clicking here.

First time installation

0. Install Firebird database version 2.5 on your Linux system.

Any of the Firebird server modes ("Classic", "SuperClassic", "Super Server") are ok, I use Super Server. Click here for the steps which I took.

1. In Linux create a Cashac folder, eg "/home/myuser/cashac/"

Download the Cashac executable as above. Move the downloaded file into your Cashac folder. Set file permissions to allow this file to run as a program.

2. Create a default data folder subsidiary to your Cashac folder named "data", eg "/home/myuser/cashac/data/".

3. If migrating from Windows …

- Copy data files CASHAC.FDB and CASHACDB.INI from Windows into the default Cashac data folder on Linux. You may optionally downshift these filenames as per Linux good practice (ie to "cashac.fdb" and "cashacdb.ini") but this is not a requirement.

- Make sure that no other "cashac.fdb" is in this folder - rename any that you find eg to "zcashac.fdb".

- Do not forget to copy any additional Cashac databases (eg archives) from Windows to any Linux folder of your choice.

- set file permissions on your Cashac data file(s) to “Read/Write”.

- Run Cashac3.

4. If not migrating from Windows …

- Download an empty Cashac database by clicking here. Move the downloaded file into your Cashac data folder. Set file permissions to “Read/Write”.

- Run Cashac3. After various information-only messages you will be prompted to enter the base currency (for example "GBP"). Once you have done this you are up and running.
