  • Unix/Linux simple log parser (since, until)

    - by dpb
    Has anyone ever used/created a simple unix/linux log parser that can parse logs like the following: timestamp log_message \n Order the messages, parse the timestamp, and return: All messages Messages after a certain date (--since) Messages before a certain date (--until) Combination of --since, --until I could write something like this, but wasn't sure if there was something canned. It would fit well in some automated reporting I'm planning on doing.

  • Unix: How to unsplit in screen

    - by Svish
    I'm trying to learn how to use screen, in unix so that I don't have to open up several ssh connections and terminal windows just because I want to do more than one thing at the same time on a machine. I have found the split command quite useful, but I have a problem I can't seem to figure out of... how do I unsplit?? I can split split using ^A S and switch between them using ^A ^I, but can't figure out how to remove a split...

  • Formatting the date in unix to include suffix on day (st, nd, rd and th)

    - by skymook
    How can I add the suffix on the day number of a unix date? I'll explain. I have a TextMate bundle snippit that writes out today's date. It uses unix date and formatting. Here is the code: `date +%A` `date +%d` `date +%B` `date +%Y` It outputs: Monday 22 March 2010 I would like to add the suffix to the day (st, nd, rd and th) like so: Monday 22nd March 2010 As far as I can see, there is no native function in the unix date formatting, like there is in PHP (j). How would I achieve this in unix? A complicated regex on the day number?

  • Delay-Load equivalent in unix based systems

    - by saran
    What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

  • Daemon/Software that takes changes from sql database and applies them to unix config files

    - by Dude Man
    I was wondering if there was a unix daemon available that would be capable of something like this: admin adds an IP entry to a DB; daemon finds change after wait interval and manipulates ifconfig/config files I was thinking maybe there is a plugin for cfengine that might be able to do this, but I couldn't find any. I mean this would be a fairly easy thing to script up in perl, but why re-invent the wheel if theres already something out there that is better than what my limited programming abilities can make. Lastly, if it worked on FreeBSD that'd be great.

  • UNIX-Security Advise

    - by Phoibe
    Hello, I want to build a quite secure UNIX-Server. Mechanisms I already implemented: SNORT + fwsnort for banning psad to block network-scanning attempts Portknocking to start+open SSH (key-based login - no password) hourly update of IP-Tables-Rules from a Security-Subscription Fail2Ban ClamAV & Rootkithunter + Logwatch What service-independent security mechanism would you add to this? What mechanism are you using? The server will run Apache&Postfix. For Apache hiding the server-information ofc. and nothing I can think of for Postfix. Thanks

  • UNIX install quota in ubuntu ?

    - by user52085
    I am new to UNIX and can't figure out how to use the 'quota' command to see my disk usages. So I install “quota” using the following command sudo apt-get install quota But when I type in the command quota -v or anything similar, it doesn’t show anything. According to most website online (http://acs.ucsd.edu/students/quota.shtml#check-remove) , it suppose to show me all the quota limitation when I type in quota -v. can you please tell me how can I make it work or if I am doing something wrong here. your help is greatly appreciated. Thanks.

  • Is there a Windows philosophy of programming?

    - by Maglob
    I've been programming both in Unix and Windows environments. Mostly I've worked in Unix, where I've learned Unix Philosophy, which can be summarized as Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface. There seems to be a clear difference in programming cultures between Unix and Windows worlds, for example: GUI vs CLI Registry vs config files Lots of tools specializing for any given need vs group of generic orthogonal tools which can combined Is there equivalent of "Unix philosophy" in Windows world? What Unix-programmer can learn from Windows or should be aware of when moving to programming in Windows? I would like answers to focus on the best practices of Windows programming (and not a fight between Windows and Unix).

  • Alternative to Daemontools (djbtools) to supervise unix processes?

    - by Stefan Lasiewski
    I've used Daemontools to provide a simple and reliable way to supervise Unix services on my servers. It works well, but it requires a different way of thinking (The DJB Way) and some common complaints are: TAI64N based timestamps Doesn't store scripts under /etc/init.d (or (/usr/local)/etc/rc.d) Doesn't always work with scripts like apachectl. Some scripts need to be rewritten. I remember that some similar "supervisor/watchdog" daemons were in the works about two years ago, but some were still a little rough around the edges. If you have switched from Daemontools to something else, what did you choose and did it work well for you? Does RedHat or Ubuntu come with any process supervisor utilities by default?

  • How to wrap console utils in webserver

    - by Alex Brown
    I have a big dataset (100Mbs/day) and a bunch of console a TCL/TK tools to view it - I want to turn it into a web app that I can build, and others can maintain. In long: my group runs simulations yielding 100s of Mbs of data daily, in multiple (mostly but not only) text forms. We have a bunch of scripts and tools, mostly old school 1990's style stuff requiring a 5-button mouse, as well as lots of ad-hoc scripts that engineers build out of frustration every month or so. These produces UIs, graphs, spreadsheets (various sizes), logs, event histories etc. I want to replace (or at least supplement) the xwindows / console style UI with a web-based one, so I need the following properties: pleasant to program can wrap existing command-line tools in separate views (I don't need to scrape GUIs or anything) as I port logic from the existing scripts I can create a modularised and pleasant codebase to replace it I can attach a web-ui to navigate between views - each view is likely to contain keys which might make sense to view in another I am new to building systems that have logic on the back-end and front-end of a web-server. from that point of view, they do this: backend wraps old-school executables, constructs calls into them and them takes the output and wraps it up, niceifies it and delivers it to the web client. For instance the tool might generate a number of indexed images (per invocation) which I might deliver all at once or on-demand. May (probably) need to to heavy stats on some sources. frontend provides navigation connecting multiple views, performs requests from one view for data from another (or self to self), etc. Probably will have some views with a lot of interactivity. Can people please point me towards viable solutions for this? I know it's a bit of an open question so as answers come in I hope to refine the spec until we have a good match. I guess I expect to see answers like "RoR!" "beans!" "Scala!" but please give an indication of why those are a good fit; I know nothing! I got bumped off SO for asking an open-ended question, so sorry if its OT here too (let me know). I take the policy that I use the best/closest matched language for a project but most of my team are extremely low level (ie pipeline stages and CDyn) so I don't have the peer group to know where to start.

  • How to properly shutdown or reboot a Unix/Linux server

    - by hatorade
    What is the correct way to turn off a Unix/Linux server? From my googling, I have learned (hopefully) the following: shutdown: I should use this, with the parameter -h to halt, or the parameter -r to reboot halt: halts the computer (stops the processor? does this physically turn the power of the computer off?). I think this will call shutdown if not at init0, otherwise just halts. reboot: if not at init6, calls shutdown, otherwise just reboots the computer. if all that is correct, then the only thing I can't figure out is what exactly 'halt' does. Does it just stop the processor but not turn the computer physically off? How do I "poweroff" the computer? Thanks

  • Generic tool to configure startup applications on Unix

    - by srid
    Is there an automated deployment tool that manages startup applications on a variety of machines, especially the Unices? Or is the only hope to study the nuts and bolts of each Unix (osx, linux, solaris, hpux, aix) on how to configure applications to launch on system startup? I want to run them as a specific user, instead of root. At the moment, I run them all within a screen session .. which is a hassle, as this requires manual intervention every time the machine is rebooted for some reason. Ideally, I am looking for a tool that would read, say, ~/.startup-programs which file contains, on each line, the command line to launch the needed daemons. And this tool should work on OSX, Linux, Solaris, HPUX and AIX ... writing the appropriate startup scripts for each platform.

  • How to run programs from a different directory in unix

    - by user1067358
    I know this is a very simple question, and that many similar (but more complicated!) questions have been asked- So i wanted to ask this in a very plane manner. Sorry if this voids the rules of conduct on this website! I'm very new to using unix. I have a program that converts a ".evt" file to an .rq1, which is used for data analysis. The command to do so is simple, for example: Convert data.evt (this outputs data.rq1). This program, let's say, is located in directory /A and I have a data file that I want to convert in directory /B. How would I go about executing this program without moving the convert program to directory B?

  • Unix file permission for groups

    - by GOPI
    I am working on HP Unix server. I have a directory in which users from different groups need to create files. And the users of a same group should have complete access to the files created by their group and only read access for the files created by other groups. I tried to set sticky bit for the directory thereby to restrict access for other groups. But I face the following problem. Created File1 from user1 of GroupA. When I tried to execute the 'rm' command from user2 of the same group GroupA, it doesn't allow as user2 is not the owner of the file. can setgid (at directory level) or other command help me to sort this issue?

  • Unix: sleep until the specified time

    - by aix
    Is there a (semi-)standard Unix command that would sleep until the time specified on its command line? In other words, I am looking for something similar to sleep that would take wakeup time rather than duration. For example: sleeptill 05:00:00 I can code something up but would rather not re-invent the wheel if there's already something out there. Bonus question: it would be great if it could take the timezone (as in sleeptill 05:00:00 America/New_York). edit Due to the nature of what I am doing, I am looking for a "sleep until T" rather than "run command at T" solution. edit For the avoidance of doubt, if I run the command at 18:00 and tell it to wake up at 17:00, I expect it to sleep for 23 hours (or, in some corner cases having to do with daylight savings time, for 22 or 24 hours.)

  • Comparison of Unix shells

    - by Andy White
    Of the major Unix shells (bash, ksh, tcsh, zsh, others?), are there any compelling reasons to use one over another? Which is the most interactive/command-line friendly? Which is the most conducive/intuitive for writing scripts? Are there any major built-in features that one shell offers that others don't? Are any of these shells really good for one type of function, but not another? Or are they all pretty well-rounded/flexible? Is it just a matter of personal preference? I can make this community wiki if anyone prefers.

  • What are the useful UNIX functions that MS doesn't implement? And why? [closed]

    - by prosseek
    When programming with Python, I came across some functions that are not implemented on Windows. os.fork() may be one of them. UNIX came before WinNT, so the WinNT developers (most notably Dave Cutler) must knew about the features and functions of the UNIX. But, to me, it seems that MS didn't like UNIX so much that they mistakenly/intentionally skipped or distorted some of the useful UNIX functions/features; i.e. /abc/def in UNIX, \abc\def in Windows as an easy example. And when I read the Windows System Programming book, I felt uncomfortable as the Windows system functions seem nothing more than a tweak from UNIX. (I might be wrong.) What are those functions/features that MS OSes don't have, but UNIX origninated? Is there any reason for this? Do they just want to differentiate from UNIX world? Or do they think some of the UNIX functions are unnecessary? Is Windows a tweak from UNIX? Or, is there any great OS features that were invented in MS to make Windows better than UNIX?
