  • Regarding PID Shell Script

    - by arav
    I am calling another shell script testarg.sh within my main script. the logfiles of testarg.sh are stored in $CUSTLOGS in the below format testarg.DDMONYY.PID.log example: testarg.09Jun10.21165.log In the main script after the testarg process gets completed i need to grep the log file for the text "ERROR" and "COMPLETED SUCCESSFULLY". How do i get the PID of the process and combine with DDMONYY for grepping. Also i need to check whether file exists before grepping $CUSTBIN/testarg.sh $CUSTBIN/testarg.sh rc=$? if [ $rc -ne 0 ]; then return $CODE_WARN fi

  • Need ideas for reprocessing images using attachment_fu

    - by cswebgrl
    Hi, I discovered a bug in my Rails app due to Rails app and gems upgrades and undocumented code from the previous developers. I have a lot of images that have been processed, but not sized correctly using attachment_fu. All of the images that were uploaded since the upgrade need to be resized correctly. Does anyone have any ideas to reprocess all of the images within the folders and resize them to the correct sizes? I'd hate to have to do these all manually. THANKS!! Cindy

  • Custom Output => List of Errors interpretation in VS2008 IDE.

    - by Hamish Grubijan
    Hello, I have a "database solution" project in VS2008 - it generates SQL for more than one DB vendor from some sort of templates. In order to save time, I also have a tool in VS2008 configured (a Python script), which can compile an individual stored procedure. Now, with the Python script I have the freedom of processing the output and have it take on whatever form I want. I am toying with an idea of having these errors and warnings somehow recognized and populating the click-able Error / Warning list. This is what a typical Oracle error looks like: LINE/COL ERROR -------- ----------------------------------------------------------------- 324/5 PL/SQL: Statement ignored 324/82 PLS-00363: expression 'VSOURCE_SYSTEM_ID' cannot be used as an assignment target Warning: Procedure created with compilation errors. PROCEDURE: ADD_PROPOSED error on creation Errors for PROCEDURE ADD_PROPOSED: LINE/COL ERROR This might be a long shot, but it is worthwhile for me. I do this stuff a lot. Thank you!

  • How can I use git to stage only one line in a file for commit, all from a script?

    - by Sandy
    I'm writing a simple pre-commit git hook that updates the year in copyright headers for files that are staged for commit. After modifying the line with the copyright, I would like the hook to stage that line so that it is part of the commit. It can't just git add the whole file, because there may be other pre-existing changes in there that shouldn't be staged. I don't see any options in the git add manual the let you stage specific lines. I figure I could git stash save --keep-index, apply my change, git add the file, and then git stash pop, but that seems rather crude. Any better approaches?

  • How do I call Matlab in a script on Windows?

    - by Benjamin Oakes
    I'm working on a project that uses several languages: SQL for querying a database Perl/Ruby for quick-and-dirty processing of the data from the database and some other bookkeeping Matlab for matrix-oriented computations Various statistics languages (SAS/R/SPSS) for processing the Matlab output Each language fits its niche well and we already have a fair amount of code in each. Right now, there's a lot of manual work to run all these steps that would be much better scripted. I've already done this on Linux, and it works relatively well. On Linux: matlab -nosplash -nodesktop -r "command" or echo "command" | matlab -nosplash -nodesktop ...opens Matlab in a "command line" mode. (That is, no windows are created -- it just reads from STDIN, executes, and outputs to STDOUT/STDERR.) My problem is that on Windows (XP and 7), this same code opens up a window and doesn't read from / write to the command line. It just stares me blankly in the face, totally ignoring STDIN and STDOUT. How can I script running Matlab commands on Windows? I basically want something that will do: ruby database_query.rb perl legacy_code.pl ruby other_stuff.rb matlab processing_step_1.m matlab processing_step_2.m # etc, etc. I've found out that Matlab has an -automation flag on Windows to start an "automation server". That sounds like overkill for my purposes, and I'd like something that works on both platforms. What options do I have for automating Matlab in this workflow?

  • (UNITY3D) Get slerp to work just as LookAt(,Vector3.right) does

    - by Ben Rokah
    Ive been working over a sidescroller shooter game. Ive got my sidescroller shooter character to look around with these : chest.LookAt(mousepos,Vector3.right); & chest.LookAt(mousepos,Vector3.left); (Left when the character is turned to the left and right when the character is turned to the right) so it wont aim in to any other axis... But when the mouse gets to cross the middle of the character and not around it it gets the rotation to make a small transportation between frames and it wont get all the way to there.. It'll just teleport to its correct rotation like lookat should. Well the question is, how do I get any quaternion slerp which works with a Time.deltTime to work as same as LookAt(,Vector3.right)? I must have the Vector3.right and left so it'll move trough 1 axis. Many thanks to anyone who helps me out. :)

  • script to sum all numbers in a file (linux)

    - by Mark Roberts
    I have a file which contains several thousand numbers, each on it's own line: 34 42 11 6 2 99 ... I'm looking to write a script which will print the sum of all numbers in the file. I've got a solution, but it's not very efficient. (It takes several minutes to run.) I'm looking for a more efficient solution. Any suggestions?

  • How to bundle C code in C shell script?

    - by eSKay
    I have a C shell script that calls two C programs - one after the another with some file handling before, in-between and afterwards. Now, as such I have three different files - one C shell script and 2 .c files. I need to give this script to other users. The problem is that I have to distribute three files - which the users must keep in the same folder and then execute the script. Is there some better way to do this? [I know I can make one C code file out of those two... but I will still be left with a shell script and a C code. Actually, the two C codes do entirely different things... so I want them to be separate]

  • How to perform an action when file changed?

    - by ZeissS
    Hi, I want to create a script that checks an URL and perform an action (download + unzip) when the "Last-Modified" header of the remote file changed. I thought about fetching the header with curl but then I have to store it somewhere for each file and perform a date comparison. Does anyone have a different idea using (mostly) standard unix tools? thanks

  • How to resume an ftp download at any point? (shell script, wget option)?

    - by Dave
    hi! i want to download a huge file from an ftp server in chunks of 50-100MB each. At each point, i want to be able to set the "starting" point and the length of the chunk i want. i wont have the "previous" chunks saved locally (ie i cant ask the program to "resume" the downlaod). what is the best way of going about that? i use wget mostly, but would something else be better?

  • Unable to parse variable length string separated by delimiter

    - by Technext
    Hi, I have a problem with parsing a string, which consists only of directory path. For ex. My input string is Abc\Program Files\sample\ My output should be Abc//Program Files//sample The script should work for input path of any length i.e., it can contain any no. of subdirectories. (For ex., abc\temp\sample\folder\joe) I have looked for help in many links but to no avail. Looks like FOR command extracts only one whole line or a string (when we use ‘token’ keyword in FOR syntax) but my problem is that I am not aware of the input path length and hence, the no. of tokens. My idea was to use \ as a delimiter and then extract each word before and after it (), and put the words to an output file along with // till we reach the end of the string. I tried implementing the following but it did not work: @echo off FOR /F "delims=\" %%x in (orig.txt) do ( IF NOT %%x == "" echo.%%x//output.txt ) The file orig.txt contains only one line i.e, Abc\Program Files\sample\ The output that I get contains only: Abc// The above output contains blank spaces as well after ‘Abc//’ My desired output should be: Abc//program Files//sample// Can anyone please help me with this? Regards, Technext
