  • Simple tool to graph memory usage?

    - by dbr
    Is there a script that will show memory usage as a graph, for example as a pie-chart, with each process being being a separate slice? I'm not looking for something like Munin to graph memory usage over time, but rather show the memory usage per-process at a single point in time. To make my request even more obscure, it is for a headless server (so no X applications). The simplest way would be to write a PNG file, or possibly an HTML file (which could use Javascript to allow the filtering of processes, changing between graph-types and so on)

  • Extracting Windows executable installers on Mac Os X?

    - by James McMahon
    Is there a program or a script out there to extract the contents of a Windows installer under Mac Os X? Under Windows there is the Universal Extractor, I am looking like something like that for Mac. I don't know if there is a universal solution to this problem or if I would need a extractor specific to the type of installer. In my case I am actually trying to get the installer from Gog.com to extract so I can use them with Boxer.

  • Run a batch file before user logs into Windows 2003 R2?

    - by Sid
    I have an Amazon EC2 machine (Windows Server 2003 R2) where I want to run a script (.bat file) when the Windows Server 2003 R2 machine boots up. This need to run BEFORE any user logs in. Ideally I'd like to extend the same work-around on my Windows Server 2008 R2 instances too - but Windows Server 2003 R2 is critical for me as of now. Purely as FYI, the .bat file updates the DDNS records so the EC2 machine doesn't need to consume static IPs.

  • mysqldump triggering repair of MySQL tables

    - by Rhodri
    I have an automated backup of a 6 Gigabyte MySQL database running very two hours. I also have a script which checks every minute for the need to repair MySQL tables. Increasingly I'm getting tables having to be repaired during the backup process with the message returned of: Auto-increment value: 0 is smaller than max used value: xx Is this being caused by corruption? Are the two scripts conflicting? Any ideas?

  • remotely running find -exec options

    - by Michael Merchant
    I'm trying to setup a bash process for deploying my django project onto a linux server. Through cygwin, I'm running a script that is calling scp to copy my files over. Is there a similar command to delete *.pyc files. As of now, I've only been able to accomplish this locally after using ssh with: find . -name "*.pyc" -exec rm -rf {} \; I'm looking for some kind of command to call remotely that would be equivalent.

I get this error email: /bin/bash: 555: command not found I have tried setting shell to /bin/sh but it makes no difference. I still get an analogous error message.

  • Run Crontab anytime after 4pm

    - by EasilyBaffled
    I am trying to run a script through crontab in osx 10.8.5 that will run at 4:30. 30 16 * * 1-5 /Library/Frameworks/Python.framework/Versions/2.7/bin/python /Users/lego90511/PycharmProjects/Stock\ Scanner/stock_scanner.py But I realized today that, my computer is not always on at 4:30. So I added the fix * 16 * * 1-5. But then I realized it may not be at all between 4-5. How can I set crontab to run anytime after 4pm(16 cron time)?

  • how to diagnosis and resolve: /usr/lib64/libz.so.1: no version information available

    - by matchew
    I had a hell of a time installing lxml for python2.7 on centOs5.6. For some background, python2.7 is an alternative installation of python on centOS5.6 which comes with python2.4 installed. it was bulit from source per its instrucitons ./configure make make altinstall However, after about 20 hours of trying I managed to find a workable solution and was able to install lxml. Until, I notice the following error at the top of the interpreter: python2.7: /usr/lib64/libz.so.1: no version information available (required by python2.7) Python 2.7.2 (default, Jun 30 2011, 18:55:26) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> print 'Sheeeeut!' this error is printed out everytime I run a script. For example: $ ./test.py /usr/local/bin/python2.7: /usr/lib64/libz.so.1: no version information available (required by /usr/local/bin/python2.7) the script runs flawlessly, but this error is bothersome. After some digging I have seem to believe I have a wrong version of libz installed, that it is either an older version or built for a different platform. I'm not quite sure how, I've only installed libz through yum, as far as I know. Although, I can't quite remember every little thing I tried in my twenty hours of trying. You may also be intereted in what my lib64 folder looks like, here is some information $ ls -ltrh libz* -rwxr-xr-x 1 root root 84K Jan 9 2007 libz.so.1.2.3 -rwxr-xr-x 1 root root 107K Jan 9 2007 libz.a -rwxr-xr-x 1 root root 154K Feb 22 23:30 libzdb.so.7.0.2 lrwxrwxrwx 1 root root 13 Apr 20 20:46 libz.so.1 -> libz.so.1.2.3 lrwxrwxrwx 1 root root 15 Jun 30 18:43 libzdb.so.7 -> libzdb.so.7.0.2 lrwxrwxrwx 1 root root 13 Jul 1 11:35 libz.so -> libz.so.1.2.3 lrwxrwxrwx 1 root root 15 Jul 1 11:35 libzdb.so -> libzdb.so.7.0.2 notice: the items that Say Jul 1st or Jun 30th are from me. I had initially moved these files into a backup folder as they seeemed to be 1. duplicates and 2. had a date after/during my problems I alluded to earlier that I had with lxml One inclination is to completely remove python2.7 and re-install. I think having it install to /usr/local/ was a poor default choice. However, without the make uninstall option being present it seems to be a time consuming task for a solution I am not quite sure would solve my problem.
