Hi Leor,
: DBPATH="/u2/mfaurot/db/phone export DBPATH isql phone - < EOF 2&1 | more select * from ph_work where name_last matches "*$1*" order by name_last; EOF
The key is an undocumented (at least it was the last time I remember looking for this in a manual) switch: the "-" after the database name and before the << redirection. You can also get a command line driven version of isql by doing:
isql - -
Just send an EOF (^d) when you're ready to return to your shell or calling program.
Michael Faurot, Yes, several folks have pointed this out, but yours is the most detailed explanation. I'm relieved to hear this feature is indeed undocumented, because I know I tried to look it up in the manual at one point. All I can say is that somewhere, out there, must be an application that really doesn't accept standard input to which one might apply my technique . . . Thanks, --lz
To: Laurie Sefton I do have one small improvement on searching for setuid and setgid files. In SunOS 4.1.2, the manpages for find describe the -perm operator this way:
-perm onum
True if the file permission flags exactly match the octal number onum (see chmod(1V)). If onum is prefixed by a minus sign, more flag bits (017777, see chmod(1V)) become significant and the flags are compared: (flags&onum)==onum. If the specified permissions are prefixed by a minus sign, you can search for files with permissions that match what you're looking for, but may also have other permissions set. For example, this is how I search for setuid files:
find / -perm -4000 -print
For setgid files:
find / -perm -6000 -print
Those commands will find any setuid or setgid file regardless of how the user, group, or other permissions are set. Also, on redirecting the output to a file, I find it more convenient to pipe it through mail:
find / -perm -4000 -print | mail lsloan &
I liked your article and I would recommend to anybody that they keep a copy of it around for reference.
Lance Sloan We've forwarded your message to Laurie Sefton but wanted to share it with our readers also. Thank you for writing. --mm
Hello, Sys Admin mag: However, I've just entered a subscription and the expiration date on my mailer label is: May 93. My question is: I just subscribed to Sys Admin in Oct, 1992. If the subscription ends May 93 I only receive 1/2 year of your most excellent publication. Hoping for email reply (if this is possible ) to skinman@pops.navo.navy.mil
Best Wishes for Success Thanks for the nice words -- we'll try to cover some of the subjects you mention in upcoming issues. As for the misleading information included on your mailing label: it seems that our label program forgot that Sys Admin was a bimonthly magazine -- thus interpreted 2.5 (your actual expiration issue) as May rather than September/October. The actual data concerning your account is all in order, and I believe we've fixed the label problem. Our apologies to you and all others who were inconvenienced by this glitch! --mm
To: rdpub!saletter Congratulations on the new magazine. If your first issues are any measure, you folks look to have a winner on your hands. It would be nice if there was more coverage of stuff for Data Genera AViiONs, but I expect you can only print what someone's submitted. Maybe this'll nudge someone into writing something. Have you ever considered running a regular feature that covers system management tools that are available over the Internet? It looks like there's a lot of useful public domain/freely redistributable stuff floating out there -- unfortunately, not only is it all scattered around and difficult to find out about, there are a lot of us who only have access via UUCP through UUNet. Even one-paragraph descriptions, along with file names and locations, would be a real help.
Dan Sugalski I think that's a good idea. In fact, it seems I've seen a summary somewhere in one of the news feeds. Perhaps one of our readers can help me find it, or write one? --rlw

Hi,
Keith Hollister Gee, I'll invite you to all my evaluations. Thanks. --rlw
To: saletter@rdpub.com I'd like to see an article (or six) on how NetNews works. I'm thinking of topics such as nntp protocol, how news servers work, what's involved in setting up a server served by dialup, what's involved in maintaining a server. I realize that some of this is covered by O'Reilly books, but I'd like to see a capsule summary of these topics to de-mystify them for the sysadmin who's considering adding news to a machine. I've used nn a little, so I know what the user sees. What I want to know is what goes on under the hood.
Kenneth Porter Another good suggestion, at least I'd certainly like to know more about how this stuff works. So, do we have an author out there? You write it, I'll print it. --rlw

Hi: Like the journal....keep the good stuff coming!
Mal Raff All the code is already available on uunet. For our reader's convenience, we run a small "house ad" in every issue which includes more details about network access. This ad is indexed in the "Departments" section of the table of contents (on the cover) under "Source Code Availability". --rlw
