  • symlink files newer than X age, then later remove symlink once file ages?

    - by bleomycin
    Hello everyone, i have a large number of files/folders coming in each day that are being sorted automatically to a wide variety of folders. I'm looking for a way to automatically find these files/folders and create symlinks to them all within an "incoming" folder. Searching for file age should be sufficient for finding the files, however searching for age and owner would be ideal. Then once the files/folders being linked to reach a certain age, say 5 days, remove the symlinks to them automatically from the "incoming" folder. Is this possible to do with a simple shell or python script that can be run with cron? Thanks!

  • shell script segment to avoid overwriting files

    - by johndashen
    I have a perl script (or any executable) E which will take a file foo.xml and write a file foo.txt. I use a Beowulf cluster to run E for a large number of XML files, but I'd like to write a simple job server script in shell (bash) which doesn't overwrite existing txt files. I'm currently doing something like #!/bin/sh PATTERN="[A-Z]*0[1-2][a-j]"; # this matches foo in all cases todo=`ls *.xml | grep $PATTERN`; isdone=`ls *.foo | grep $PATTERN`; whatsleft=todo - isdone; # what's the unix magic? #and then call the job server; jobserve E "$whatsleft"; and then I don't know how to get the difference between $todo and $isdone. I'd prefer using sort/uniq to something like a for loop with grep inside, but I'm not sure how to do it (pipes? temporary files?) As a bonus question, is there a way to do lookahead search in bash grep?

  • how to run few vim commands in a raw

    - by temujin.ya.ru
    Hello. This is really noob question. There is set of vim commands : command1 : command2 etc., which I would neet to type in in a raw quite often. How to I make it automatic? It is simple regexp replace command set, however I cannot script those in sed, since it involves non-latin locales and for some reason vim handles non-latin regexps correctly, while sed not.

  • Text replacement for multiple script/config files

    - by user343804
    I am doing some sort of science with a combination of Python, bash scripts and configuration files with weird syntaxes from old C programs. To run different tests, I have to tune (open text file, edit and save) a number of these files, but it is getting harder and harder to remember which files to edit. Also, the tasks are very repetitive and I end having a bunch of comment lines, switching on and off the settings for a specific run. I dream of a tool that can keep a list of files (regardless of the file format) and allow me to centrally choose from a predefined list of "profiles", taking care of editing the script/config files. For example lets say I have a config and script file: config.cfg var1 = 1.0 #var1 = 1.5 script.sct function(200.0) #function(300.0) I would like to instead have auxiliary text files: config.cfg.tem var1 = $$var1$$ script.sct.tem function($$par1$$) and in a central script or even better, a GUI, just switch from profile1 (e.g. var1=1.0,par1=200.0) to profile2 (e.g. var1=1.5,par1=300.0), and the tool to automatically update the text files. Any idea if such a tools exists?

  • Shell Script Variable Quoting Problem

    - by apinstein
    I have an sh script that contains the line $PHP_COMMAND -r 'echo get_include_path();' I can not edit this script, but I need the eventual command line to be (equivalent to) php -d include_path='/path/with spaces/dir' -r 'echo get_include_path();' How can I achieve this? Below is a script that demonstrates the problem. #!/bin/sh # shell script quoting problem demonstration # I need to be able to set a shell variable with a command with # some options, like so PHP_COMMAND="php -d 'include_path=/path/with spaces/dir'" # then use PHP_COMMAND to run something in another script, like this: $PHP_COMMAND -r 'echo get_include_path();' # the above fails when executed. However, if you copy/paste the output # from this line and run it in the CLI, it works! echo "$PHP_COMMAND -r 'echo get_include_path();'" php -d include_path='/path/with spaces/dir' -r 'echo get_include_path();' # what's going on? # this is also interesting echo "\n--------------------" # this works great, but only works if include_path doesn't need quoting PHP_COMMAND="php -d include_path=/path/to/dir" echo "$PHP_COMMAND -r 'echo get_include_path();'" $PHP_COMMAND -r 'echo get_include_path();' echo "\n--------------------" # this one doesn't when run in the sh script, but again if you copy/paste # the output it does work as expected. PHP_COMMAND="php -d 'include_path=/path/to/dir'" echo "$PHP_COMMAND -r 'echo get_include_path();'" $PHP_COMMAND -r 'echo get_include_path();' Script also available online: http://gist.github.com/276500

  • How do I daemonize an arbitrary script in unix?

    - by dreeves
    I'd like a daemonizer that can turn an arbitrary, generic script or command into a daemon. There are two common cases I'd like to deal with: I have a script that should run forever. If it ever dies (or on reboot), restart it. Don't let there ever be two copies running at once (detect if a copy is already running and don't launch it in that case). I have a simple script or command line command that I'd like to keep executing repeatedly forever (with a short pause between runs). Again, don't allow two copies of the script to ever be running at once. Of course it's trivial to write a "while(true)" loop around the script in case 2 and then apply a solution for case 1, but a more general solution will just solve case 2 directly since that applies to the script in case 1 as well (you may just want a shorter or no pause if the script is not intended to ever die (of course if the script really does never die then the pause doesn't actually matter)). Note that the solution should not involve, say, adding file-locking code or PID recording to the existing scripts. More specifically, I'd like a program "daemonize" that I can run like % daemonize myscript arg1 arg2 or, for example, % daemonize 'echo `date` >> /tmp/times.txt' which would keep a growing list of dates appended to times.txt. (Note that if the argument(s) to daemonize is a script that runs forever as in case 1 above, then daemonize will still do the right thing, restarting it when necessary.) I could then put a command like above in my .login and/or cron it hourly or minutely (depending on how worried I was about it dying unexpectedly). NB: The daemonize script will need to remember the command string it is daemonizing so that if the same command string is daemonized again it does not launch a second copy. Also, the solution should ideally work on both OS X and linux but solutions for one or the other are welcome. (If I'm thinking of this all wrong or there are quick-and-dirty partial solutions, I'd love to hear that too.)

  • Bash command that prints a message on stderr

    I want to know if there is a built-in BASH command that prints some text on stderr, just like the echo command that prints text on stdout. I don't want to use temporary io-redirection. I use a built-in command to generate an error on stderr such as ls --asdf (ls: unrecognized option '--asdf') but I want something neater,

  • How do I convert filenames from unicode to ascii

    - by zedwarth
    I have a bunch of music files on a NTFS partition mounted on linux that have filenames with unicode characters. I'm having trouble writing a script to rename the files so that all of the file names use only ASCII characters. I think that using the iconv command should work, but I'm having trouble escaping the characters for the mv command.

  • Enter a letter when prompted by another command

    - by kij
    Hi all, I'm trying to automate the installation and deployement of an application. To do it, i have a shell script with the following instructions: /usr/local/bin/amf install -u $1 -p $2 $localTarget where $1, $2 and $localTarget are options for the command named 'amf'. The problem is that the 'amf' command make severall instructions and ask the user to enter a letter during those instructions (to confirm the installation). At the moment, i can't bypass or modify the behaviour of the 'amf' command, so my question is: How can i catch this behaviour and/or automatically enter a letter in my script. This behaviour currently make my script not working, because the 'amf instal...' instruction is followed by another command to start my application. But as the install failed, the application can't start. Thanks in advance for your help. Best regards. Kij.

  • How to script a URL screenshot without X?

    - by cwopen
    I'd like to automate a 'screenshot' of arbitary URL's using a Linux build that doesn't have X installed. There appears to be some (costly) web services to do this, but I specifically want something I can do locally. Tried imagemagick without much success, though Mozilla used to have a command line option to do it?

  • Please help me with a Power shell Script which rearranges Paths.

    - by Hamish Grubijan
    Hi, I have both Sybase and MSFT SQL Servers installed. There is a time when Sybase interferes with MS SQL because they have they have some overlapping commands. So, I need two scripts: A) When runs, script A backs up the current path, grabs all paths that contain sybase or SYBASE or SyBASE (you get the point) in them and move them all at the very end of the path, while preserving the order. B) When it runs, script B restores the path from back-up. Both script a and script b should affect the path immediately. So, if a.bat that calls patha.ps1, pathb.ps1 looks like so: @REM Old path here call patha.ps1 @REM At this point the effective path should be different. call pathb.ps1 @REM Effective old path again Please let me know if this does not make sense. I am not sure if call command is the best one to use. I have never used P.S. before. I can try to formulate the same thing in Python (I know S.O. users tend to ask for "What have you tried so far"). Well, at this point I am VERY slow at writing anything in Power Shell language. Please help.
