untagged files. For a description of the default behavior, see
“Automatic conversion and file tagging behavior for mv.”
–O u | c=codeset
Allow automatic conversion on source and target files.
–O u If the target exists and is not empty or already
tagged, mv will not change the target’s tag in order
for the target to be a candidate for automatic
conversion.
For new targets and existing, untagged, empty files,
this option has no effect and mv behaves the same
as the default. For a description of the default
behavior, see “Automatic conversion and file
tagging behavior for mv.”
When using mv to move from a UNIX file to an
MVS data set, if the source is a tagged text file,
then it may be a candidate for automatic
conversion.
When using mv to move executables from or to
MVS, automatic conversion is disabled for both
source and target.
–O c=codeset For a detailed description of the behavior of this
option on mv, see “Automatic conversion and file
tagging behavior for mv.” To prevent the corruption
of text files, mv will fail if it cannot set the tag to
text or codeset.
Attention: If automatic conversion is not set
properly or the source is not tagged properly, the
target may end up with a tag codeset which does
not match the file content.
Automatic conversion and file tagging behavior for mv
The following tables describe the behavior of file tagging and automatic conversion
for various source and target scenarios depending on whether the –O option is
specified on the mv command.
