ARCHIVED: What is EBCDIC?
Introduced by IBM and based on punch card standards, EBCDIC (Extended Binary Coded Decimal Interchange Code) is a family of 8-bit character sets used by many mainframe computers. Though often referred to as a single entity, there are several variant EBCDIC sets, primarily to accommodate language differences.
In Unix, you can convert between ASCII and EBCDIC with the dd command. To convert an ASCII file into EBCDIC, at the Unix prompt, enter:
dd if=inputfile of=outputfile conv=ebcdic
To transform an EBCDIC file into ASCII, enter:
dd if=inputfile of=outputfile conv=ascii
Replace inputfile
with the file you wish to convert and
outputfile
with the name of the converted file. For more
information on the dd command, see its man file. At the Unix
prompt, enter:
man dd
The table below contains the character mappings for the EBCDIC US-Canada set. Characters that cannot be represented in ASCII are noted by a brief description.
