Hello,

 

I am converting some UNIX programs to Linux.

 

One of the programs does the following:

 dd if=20140430.1.EBC.TXT of=tmpUNIX.dat cbs=152 conv=ascii

 

In Solaris I get this:

461614+1 records in

368585+1 records out

 

In Linux I get this:

461614+1 records in

461614+1 records out

236346472 bytes (236 MB) copied, 11.4938 seconds, 20.6 MB/s

 

The cksum done on 20140430.1.EBC.TXT yields the same result on both Linux and UNIX.

 

 

uname –a

SunOS dsa0401 5.10 Generic_142900-03 sun4v sparc SUNW,SPARC-Enterprise-T5220

 

Linux dla0614.ccrt.us 2.6.18-371.1.2.el5 #1 SMP Tue Oct 22 11:40:34 CDT 2013 x86_64 x86_64 x86_64 GNU/Linux

 

Any help would be appreciated.

 

Thanks,

Don

Who would have thought that after all these years, GNU 'dd' would still be mishandling EBCDIC conversion? The GNU dd implementation of conv=ascii is clearly incorrect. I installed the attached patch. Please give it a try if you can. I am closing the bug report for convenience, but we can reopen it if the patch does not work for you.
