Q: Looking for tail for VMS

: Hi everyone.
: Is there anybody who knows where I can find the Unix 'tail'-command

From an OpenVMS VAX V6.1 system:
$ help type/tail
TYPE
/TAIL
/TAIL[=n]
Displays the last several lines of a log file. The value, n,
defaults to p-2 where p is the current terminal page length. You
can use TYPE/TAIL only if all of the following are true:
o file organization is sequential
o the longest record is less than 512 bytes
o the record format is either VAR, VFC, STM, STRCM or STMLF
(for more information, see the description of FAB$B_RFM in the
OpenVMS Record Management Services Reference Manual)

****DISCLAIMER****
I have not worked on a UN*X system for aprx. 8 years, and my memory 'aint
that good. Looks like the 'tail' command displays the last X lines of a text
file. If this is not what is being looked for, don't read this post. X>
******************
Klaus,
If you don't have the VMS 6.x with the /TAIL qualifier, check the spring '92
VAX SIG tape for VLOG. It was written for me by Alan Zirkle here at NSWC.
It allowed our DB people here to track the log files of database
unload/reload batch jobs that ran for days. The log files for these jobs
took a long-long time to TYPE each time they wanted to check their progress.
It also allows you to provide a filename, and using RMS routines, jumps to
the end of the file and displays the last X lines. It works on most text
files, with some minor restrictions.
Let me know if you are interested and can't find it.

HELP TYPE/TAIL
You'll get this:
TYPE
/TAIL
/TAIL[=n]
Displays the last several lines of a log file. The value, n,
defaults to p-2 where p is the current terminal page length. You
can use TYPE/TAIL only if all of the following are true:
o file organization is sequential
o the longest record is less than 512 bytes
o the record format is either VAR, VFC, STM, STRCM or STMLF
(for more information, see the description of FAB$B_RFM in the
OpenVMS Record Management Services Reference Manual)
It should do what you want:

A number of people have posted the answer that VMS 6.1 has a TYPE/TAIL
option now. However, if you want to try another route, I have a copy of a
version of Tail written in C by D. Shepperd at Atari games which I use
here. It's got a couple of nice options such as rereading a log file that's
being written to every user-specified seconds, etc.
I can't say for sure, but it also appears to be able to read more formats
of files as well.
Anyways, if you're interested, I can send you the source.

#for VAX-VMS ?
"$ TYPE/TAIL" was added to VMS in V6.1 or V6.0.

While TYPE/TAIL will almost certainly NOT be a clone of unix
tail, that is, have the same syntax and every conceivable option,
I'm still puzzled by your statement above.
First, in OVMS 6.1, the TYPE command supports, in addition to
/TAIL, the /CONTINUOUS /INTERVAL=n qualifiers which allows you to
look at log files (and other files) as they are being written
(assuming the application is updating the file and allows shared
read access). Furthermore, the /PAGE qualifier has been greatly
enhanced to allow scrolling forward and backward, and left and
right, etc., through the text, and as well as searching for strings.
Even nicer, the /PAGE qualifier with these nice "editing" features
(also know as "Output Navigation") has been added to DIFFERENCES,
DIRECTORY, DUMP, HELP, SEARCH, and a number of SHOW commands. :-)
Second, I don't understand what you mean by, "it also appears to
be able to read more formats of files as well." TYPE can certainly
output anything you give it, and if it's text, you may even be able
to read it. What "more formats" are you thinking of???
Now if the original poster, who didn't give specifics for
his/her system, is not at OVMS 6.0 or 6.1, there are a number of
freeware tail clones available (MOST comes to mind although I
haven't used it). The one I like the best is EPYT (yep, that's
"TYPE" spelled backwards :-), by Charles van den Ouweland. You can
get EPYT from FTP.WKU.EDU (and its mirrors) and from FTP.KCL.AC.UK.

Er, only to get tail...
Try the software package EXTRACT, which provides 'head' and 'tail'.
You can get it via anonymous ftp HAMLET.CALTECH.EDU.
Check that out...

Is there anybody who knows where I can find the Unix 'tail'-command
for VAX-VMS ?
Any help is highly appreciated.
