vmsbackup - read a VMS backup save_set

SYNOPSIS

       vmsbackup -{tx}[cdevwB][b blocksize]
                              [s setnumber]
                              [f tapefile]  [ name ... ]

DESCRIPTION

vmsbackup reads a VMS generated backup save_set, converting the files to Unix format and writing the files to disk. The default operation of the program is to go through an entire save_set, extracting every file and writing it to disk. This may be modified by the following options.

The optional name argument specifies one or more filenames to be searched for specifically on the save_set and only those files are to be processed .
c
Use complete filenames, including the version number. A colon and the octal version number will be appended to all filenames. A colon, rather than a semicolon, is used since the Unix Shell uses the semicolon as the line separator, so the semicolon would have to be escaped. This option is useful only when multiple versions of the same file are in a single save_set or when a file of the same name already exists in the destination directory. The default is to ignore version numbers.
d
Use the directory structure from VMS. The default value is off.
e
Process all filename extensions. Since this program is mainly intended to move source code and possibly data from a DEC system to a Unix system, the default is to ignore all files whose filename extension specifies system dependent data. The file types which will be ignored, unless the e option is specified, are :
```
   exe VMS executable file
   lib VMS object library file
   obj RSX object file
   odl RSX overlay description file
   olb RSX object library file
   pmd RSX post mortem dump file
   stb RSX task symbol table file
   sys RSX bootable system file
   tsk RSX executable task file
```
f
The next argument in the command line names the saveset file. The file may be a tape device or a disk file. The default is taken from the TAPE environment variable.
t
Produce a table of contents (a directory listing) of the save_set on the standard output.
v
Verbose output. Normally vmsbackup does its work silently. The verbose option will cause the filenames of the files being read from tape to disk to be output on the standard output.
w
vmsbackup prints the action to be taken followed by file name, then waits for user confirmation. If a word beginning with `y' is given, the action is done. Any other input means don't do it.
x
Extract the named files from the save_set.
B
Force Variable Length Record files to be output as binary. The default is text format.

ENVIRONMENT

If specified, the value of environment variable TAPE indicates the default tape device.

BUGS


The filename match uses the complete VMS file names.
