  • Write STDOUT & STDERR to a logfile, also write STDERR to screen

    - by Stefan Lasiewski
    I would like to run several commands, and capture all output to a logfile. I also want to print any errors to the screen (or optionally mail the output to someone). Here's an example. The following command will run three commands, and will write all output (STDOUT and STDERR) into a single logfile. { command1 && command2 && command3 ; } > logfile.log 2>&1 Here is what I want to do with the output of these commands: STDERR and STDOUT for all commands goes to a logfile, in case I need it later--- I usually won't look in here unless there are problems. Print STDERR to the screen (or optionally, pipe to /bin/mail), so that any error stands out and doesn't get ignored. It would be nice if the return codes were still usable, so that I could do some error handling. Maybe I want to send email if there was an error, like this: { command1 && command2 && command3 ; } logfile.log 2&1 || mailx -s "There was an error" [email protected] The problem I run into is that STDERR loses context during I/O redirection. A '2&1' will convert STDERR into STDOUT, and therefore I cannot view errors if I do 2 error.log Here are a couple juicier examples. Let's pretend that I am running some familiar build commands, but I don't want the entire build to stop just because of one error so I use the '--keep-going' flag. { ./configure && make --keep-going && make install ; } > build.log 2>&1 Or, here's a simple (And perhaps sloppy) build and deploy script, which will keep going in the event of an error. { ./configure && make --keep-going && make install && rsync -av --keep-going /foo devhost:/foo} > build-and-deploy.log 2>&1 I think what I want involves some sort of Bash I/O Redirection, but I can't figure this out.

  • adding a js method

    - by Sorin Buturugeanu
    Hi! I have a js function that is named getID which is basically return document.getElementById(id) I want to make another function, getTag that would return getElementsByTagName. The part that I can't seem to manage is that I want to be able to call them like this: getID('myid').getTag('input') = so this would return all the input elements inside the element with the id myid Thanks! ps: getTag would also have to work if it's called by it's own, but then it would just return document.getElementsByTagName

  • How do I cache WCF REST web service in IIS7?

    - by foosnazzy
    When I turn on output caching for my service it doesn't appear to be cache-worthy in IIS. It really should be since I'm returning the same JSON content over and over. The varyByQueryString option seems like it would do the trick, but since my resources are URI based, there really isn't a query string, just a path to a resource. Has anyone successfully gotten IIS to output cache a WCF REST service?

  • How to designing a generic databse whos layout may change over time?

    - by mawg
    Here's a tricky one - how do I programatically create and interrogate a database who's contents I can't really foresee? I am implementing a generic input form system. The user can create PHP forms with a WYSIWYG layout and use them for any purpose he wishes. He can also query the input. So, we have three stages: a form is designed and generated. This is a one-off procedure, although the form can be edited later. This designs the database. someone or several people make use of the form - say for daily sales reports, stock keeping, payroll, etc. Their input to the forms is written to the database. others, maybe management, can query the database and generate reports. Since these forms are generic, I can't predict the database structure - other than to say that it will reflect HTML form fields and consist of a the data input from collection of edit boxes, memos, radio buttons and the like. Questions and remarks: A) how can I best structure the database, in terms of tables and columns? What about primary keys? My first thought was to use the control name to identify each column, then I realized that the user can edit the form and rename, so that maybe "name" becomes "employee" or "wages" becomes ":salary". I am leaning towards a unique number for each. B) how best to key the rows? I was thinking of a timestamp to allow me to query and a column for the row Id from A) C) I have to handle column rename/insert/delete. Foe deletion, I am unsure whether to delete the data from the database. Even if the user is not inputting it from the form any more he may wish to query what was previously entered. Or there may be some legal requirements to retain the data. Any gotchas in column rename/insert/delete? D) For the querying, I can have my PHP interrogate the database to get column names and generate a form with a list where each entry has a database column name, a checkbox to say if it should be used in the query and, based on column type, some selection criteria. That ought to be enough to build searches like "position = 'senior salesman' and salary 50k". E) I probably have to generate some fancy charts - graphs, histograms, pie charts, etc for query results of numerical data over time. I need to find some good FOSS PHP for this. F) What else have I forgotten? This all seems very tricky to me, but I am database n00b - maybe it is simple to you gurus?

  • Programmatically printing git revision and checking for uncommitted changes

    - by Andrew Grimm
    To ensure that my scientific analysis is reproducible, I'd like to programmatically check if there are any modifications to the code base that aren't checked in, and if not, print out what commit is being used. For example, if there are uncommitted changes, it should output Warning: uncommitted changes made. This output may not be reproducible. Else, produce Current commit: d27ec73cf2f1df89cbccd41494f579e066bad6fe Ideally, it should use "plumbing", not "porcelain".

  • Runtime C function details

    - by Sridhar
    Hi, Is there any way to find particular C language function's input and output parameters from a framework (apple's ARM) during the runtime or from any method with out knowing the headers. It is a framework and there are no header files for it.I decompile it with IDA Pro and it gives me the function names but not input and output parameters information. I am able to load those private functions using dlsym. Is it possible to find the parameters info in runtime (C language or Objective C) or from IDA Pro ? Regards, Raghu

  • Parsing line and selecting values corresponding to a key

    - by gagneet
    there is a set of data which is arranged in a specific manner (as a tree), as is given below. basically a key=value pair, with some additional values at the end, which informs how many children does the branch have and some junk value. 11=1 123 2 11=1>1=45 234 1 11=1>1=45>9=16 345 1 11=1>1=45>9=16>2=34 222 1 11=1>1=45>9=16>2=34>7=0 2234 1 11=1>1=45>9=16>2=34>7=0>8=0 22345 1 11=1>1=45>9=16>2=34>7=0>8=0>0=138 22234 1 11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0 5566 1 11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0>4=0 664 1 11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0>4=0>6=10 443 1 11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0>4=0>6=10>3=11 445 0 11=1>1=47 4453 1 11=1>1=47>9=16 887 1 11=1>1=47>9=16>2=34 67 1 11=1>1=47>9=16>2=340>7=0 98 1 11=1>1=47>9=16>2=34>7=0>8=0 654 1 11=1>1=47>9=16>2=34>7=0>8=0>0=138 5789 1 11=1>1=47>9=16>2=34>7=0>8=0>0=138>5=0 9870 1 11=1>1=47>9=16>2=34>7=0>8=0>0=138>5=0>4=0 3216 1 11=1>1=47>9=16>2=34>7=0>8=0>0=138>5=0>4=0>6=10>3=11 66678 0 my problem is to get the appropriate branch from the above data, which satisfies exactly the values, which i give as the input. suppose, my input value to search in the above data stack are: 5=0 4=0 6=10 3=11 11=1 1=45 0=138 9=16 2=34 7=0 8=0 for the above given list of key-values, the function should return 11=11=459=162=347=08=00=1385=04=06=103=11 as the match. likewise, for another input file, in which another set of keys is given: 5=0 4=0 6=10 3=11 11=1 1=45 9=16 2=34 7=0 8=0 the function should return 11=11=459=162=347=08=0 1 as the match. not the last line; as that would also match all the values given in my input key, but, i want only the exact match. Also, I want to find out how many nodes were selected in the given array. (separated by ). What will be the best way to implement this kind of scenario?

  • Neural Network: Handling unavailable inputs (missing or incomplete data)

    - by Mike
    Hopefully the last NN question you'll get from me this weekend, but here goes :) Is there a way to handle an input that you "don't always know"... so it doesn't affect the weightings somehow? Soo... if I ask someone if they are male or female and they would not like to answer, is there a way to disregard this input? Perhaps by placing it squarely in the centre? (assuming 1,0 inputs at 0.5?) Thanks

  • JSF trimming white spaces

    HI, I have an input field in which I want to trim any leading/trailing whitespaces. We are using JSF and binding the input field to a backing bean in the jsp using: <h:inputText id="inputSN" value="#{regBean.inputSN}" maxlength="10"/> My question is that besides validation can this be done in the jsp? I know we can also do this using the trim() java function in the Handler, but just wondering if there is a more elegant way to achieve this in JSF. Thanks.
