Using "dd" command to format EBCDIC file to ASCII in Linux has differences with Solaris. (Doc ID 2315746.1)

Last updated on OCTOBER 20, 2022

Applies to:

Linux OS - Version Oracle Linux 6.0 to Oracle Linux 7.4 [Release OL6 to OL7U4]
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64


When using 'dd' command to convert a EBCDIC(Extended Binary Coded Decimal Interchange Code) file created in another architecture to ASCII, certain characters could not be converted.

Trying to run the same  "dd" command in Solaris or HPUX environments it convert the all the characters if the file was created on those architectures or another (Big-Endians).

How to reproduce the issue (Example):

1) Original EBCDIC is was created in a Mainframe (source) is configured to use IBM-037 (Big Endians).

2) The file EBCDIC was  convert on Solaris 10.  IN this case it is: prod_FILE_EBCDIC_Solaris.dat

3) Creating an ASCII  file in Linux:

On both methods for check We can see that the files has differences.

It can generate issues if the file is opened in another architecture. It could proceed issues in a full environment that include multi-architectures (Solaris - HPUX - IBM - Linux ).

The dd command In Linux  is provided in the package coreutils.
