SAP Solution Manager Key Generator (linux version)

February 19, 2020 4:18 pm / 1 Comment on SAP Solution Manager Key Generator (linux version)

The following bash script should produce installation key for SAP Solution Manager (SOLMAN) basing on three input values: SID, SN and HOSTNAME.
The script is based on popular VB script available here: http://kohanov.com/tmp/sap_keys.vbs
Feel free to use/modify/redistribute the script for both private and commercial use.

To use the code, just paste it into a file (ex: solmankg.sh)

Set execution rights (chmod 755 solmankg.sh)

Execute the script with three arguments: SID, SN, HOSTNAME (ex: ./solmankg.sh AA1 00 FLUFFY)
