The form of dataset lists depends on the file transfer client. To display dataset lists, on most clients users can use the
ls -l commands. Usually the
ls command shows the list with relative dataset names and possibly some additional information. The
ls -l command shows additional information formatted by the server.
When listing a PDS or PDSE, the member names are listed.
ls command without any parameters displays the content of the current working directory.
Users can also define the DSN qualifier or HFS path they want to list. To use an absolute DSN, start the prefix with "
/__"). To use a relative DSN, which will be completed with the username, start the prefix with "
Some older SSH Tectia and third-party command-line and GUI clients requires that a dot sign is added after the dataset prefix you want to display. This applies also to SSH Tectia Server for IBM z/OS file transfer clients.
For example, to list the datasets of a user's MVS home directory using absolute DSN, use the following command:
sftp> ls /__USERID.
Or using a relative DSN, use the following command:
sftp> ls /_.
To list datasets with the DSNs
USER1.TEST.PS.*, use the following command:
sftp> ls /__USER1.TEST.PS.
If the user is connected as
USER1, use the following command for an extended list:
sftp> ls -l //TEST.PS.

The fields in the extended list are:
The volume the dataset resides on.
The day on which the dataset was last referred to, or the creation date
- Record format
The RECFM or "VSAM"
- Record size
- Block size
- File type
The file type: PS, PO, POE, ESDS, KSDS, RRN
- Size Estimate
An estimate of the count of data bytes in the data set which is based on the number of used tracks, or for VSAM files, the High RBA. A 3390 track is estimated to hold 50001 bytes (the track count can be seen in the least significant digits). The size may be smaller than the number of data bytes in the data set, if it has an efficient block size. The size of the data set when transferred may differ greatly from the size estimate, depending on such factors as character encoding, line delimiters, and trailing blanks.
The relative dataset name
