On z/OS UNIX, the dos2unix utility is not included. You can achieve similar functionality using other tools available on z/OS UNIX, such as sed or tr. These tools can be used to convert DOS-style line endings (CRLF) to Unix-style line endings (LF).

For example, you can use sed to remove carriage return characters:

sed 's/\r$//' inputfile > outputfile

Or you can use tr

tr -d '\r' < inputfile > outputfile
