Invalid flag -?

[cvs]

We had a production failure on the mainframe the other day attempting to retrieve a file from a windows server. Listed below is our code and the display with the error. It appears to me that the failure was due to a file name starting with a dash "-". We receive numerous files from outside the company, and we build our file retrieval commands thru a Cobol batch program. Is dash a valid file name? If so, is there a solution to get around this error?

The problem seems to be that the $INFILE variable has the value:

-WVSUBID02951-20140107-19270397-005010X221A1 (102).dat

This causes problems, since the sftp "get" command assumes that the name starting with a dash is an "option" and not a file name.

Is this the correct remote file name?

If so, then one workaround would be to insert single quotes around name of the file in the get command, like this:


get "'$remotefile'" $localfile

that is, single quotes inside of double quotes). In the z/OS Unix shell, the outer double quotes will mean that the inner single quotes will be literal rather than quotes. After the shell process this line and substitutes variables, the cozsftp command will see something like this:

get '-WVSUBID02951-20140107-19270397-005010X221A1 (102).dat' //DD:UPLOAD

[dovetail]

Sorry, that doesn't work either

Try this:

get -- "$remotefile" $localfile

i.e. go back to just double-quotes, but add a double-dash argument, which means "there are no more options".
This causes the remotefile name to be treated as a file name, even if it starts with a dash, and not a -option

This is probably documented somewhere, but I just wanted to know which release of Co:Z SFTP supports z/OS V2.1?
