Sorry if this is a FAQ but I'm looking for a version of 'tail' that allows me display the updates to files from multiple files. e.g. $ tail -f <file1> <file2> <file3> ThanksInAdvance.....Markc..... -- Mark Coleman O _ O EMAIL: colemanm@cheops.qld.tne.oz.au Telecom Australia | FAX: +61 7 837 4704 TNE Computer Support Services ***** PH: +61 7 837 3143 Brisbane, Queensland.

The reason I asked for a multiple file tailer is that '&'ing tails tend to chew up system resources on our systems. We are currently in development/trial/production mode and hence we are keeping a close eye on errors reported in our application. If anyone is interested in copies of the said files just drop us line at my addr. in my sig below.

Checkout the `xtail' program I posted to comp.sources.misc way back when: v07i108 xtail a kind of "tail -f" for multiple files As I mention in the distributed notes, my favorite use is: xtail /usr/spool/uucp/.Log/* /local/spool/smail/log Note that those are actually directory names. xtail will watch all the files in them, and will notice when files are created or deleted there. I always keep an xtail running on one of my 386 XENIX console screens to monitor the uucp system. It tends to eat about 2% of the available CPU, which isn't too bad. By the way, there is one patch which fixes the dependancies in the Makefile. I can send it out, but it would probably be easier to just edit the Makefile and remove the `/usr/include' dependancies. -- Chip Rosenthal 512-482-8260 | Unicom Systems Development | I saw Elvis in my wtmp file. <chip@chinacat.Unicom.COM> |

It was posted in the old mod.sources group by Brent Callaghan, {ihnp4|mtuxo|pegasus}!poseidon!brent, and is available on uunet in the states. I don't know about OZ. It uses curses to split the screen into as many panes as there are files and runs a tail-f in each one. -- Dave Lampe {ames | lll-tis | sun | pyramid}!pacbell!dplace!djl (415) 455-1571 (H) (415) 462-7000 (W)

Mark Coleman was looking for program that does: |> a version of 'tail' that allows me |> display the updates to files from multiple files. |> |> e.g. $ tail -f <file1> <file2> <file3> You might want to take a look at Chip Rosenthal's "xtail" program (the 'x' in front has nothing to do with X11 though). I use it all the time; it is also able to watch directories (notices file deletion/creation). It's in our archive; details below, look for "UNIX/xtail.tar.Z" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ **> This is my ``standard-answer'' to requests for free software that I **> think our archive-service can fulfil.

We, Computer Science department, Utrecht University, are running an anonymous FTP server on one of our systems. I should say that we're NOT archiving all of "comp.sources.*". Instead, we're putting a lot of effort in trying to keep the archive up-to-date. Here are the details on anonymous FTP: ====================================== Site: archive.cs.ruu.nl [131.211.80.5] Login: "anonymous" or "ftp" Password: your email address (you@your_domain) Usage: see the ftp(1) manual on your system Hot topics: TeX stuff, Atari-ST software, Elm 2.3, NN 6.4, UNIX software, sundry documentation, ... Important: to get a description of what exactly is in the archive get the file "pub/ls-lR.Z". Also, in each sub-directory there is a file named "INDEX" that describes the software in that directory (what version, what else you need, who wrote it, etc.). Although anonymous FTP is our main goal, we're also running a mail server, because we *know* how you feel when there's plenty of beautiful software around that you can't reach. We've been in that situation for a long long time... All we ask from you is that you at least *try* to keep big requests out of the prime-time hours (nights and weekends are fine). Okay, now for how to access our mail server: ============================================ 1) The mail server can be reached at the address mail-server@cs.ruu.nl or the old-fashioned path alternative ...!uunet!mcsun!hp4nl!ruuinf!mail-server 2) The mail server understands a couple of commands, all commands must be in the message body. The first thing you might want to do is ask it for help: send HELP 3) A complete "ls-lR" listing of the archive is kept in the top-level directory, it will be updated every night. To get it, say: send ls-lR.Z Note that compressed files will be sent UUEncoded by default; we use the UUE that was posted to the net some time ago. In every subdirectory you'll find a "INDEX" file, describing the contents of that directory. So, e.g. to find out what's in the NN-6.4 directory, say: send NN-6.4/INDEX 4) Last, assume you want to get the UUE/UUD package mentioned above: send UNIX/uudecode.shar 5) If your mailer appends your fancy signature file, you might want to mark the end of the mail-server commands-list by putting an end command above the signature file. This will prevent "unknown command" messages from the mail-server program. That's all for now. If you encounter problems using the FTP service and/or the mail-server, feel free to drop me a line (by e-mail, please). thanks for your time, --[ Edwin ]-- -- Edwin Kremer (SysAdm), Dept. of Computer Science, Utrecht University Padualaan 14, P.O.
