  • Autorun a removable device in Linux

    - by Zloy Smiertniy
    I have a removable device setup so it autoruns when plugged into a Windows machine and pops up a message giving the owner's information, so it can be returned if lost. Is there a way to do this in Linux as well? It doesn't need to be complex, it can be an option in a right-click menu, or a splashscreen, or anything.

  • Get part of a string of part of regular expression?

    - by Buttink
    Im trying to make a script that will go into a directory and run my own application with each file matching a regular expression, specifically "Test[0-9]*.txt". My input filenames look like this "TestXX.txt". Now, I could just use cut and chop off the Test and .txt, but how would I do this if XX wasn't predefined to be 2 numbers? What would I do if i had "Test1.txt" ... "Test10.txt"? In other words, How would I get the [0-9]* part? Just so you know, I want to be able to make a OutputXX.txt :)

  • Bash Scripting: I want to open a set of .html files, and add line before html tag

    - by Bashn00b
    Hi guys, I have a set of .php files in a folder, I want to add text just before these lines: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" > What i want is to insert just before these lines in the html file. So just want to prepend that file before each docType declaration. However the DOCTYPE declaration is never on line 1, as there is loads of php lines before. I have this current script (where FE is the folder containing all the scripts i want to edit): for file in ${fe}*; do echo "$file" done Thanks,

  • Which file types are worth compressing (zipping) for remote storage? For which of them the compresse

    - by user193655
    I am storing documents in sql server in varbinary(max) fileds, I use filestream optionally when a user has: (DB_Size + Docs_Size) ~> 0.8 * ExpressEdition_Max_DB_Size I am currently zipping all the files, anyway this is done because the Document Read/Write work was developed 10 years ago where Storage was more expensive than now. Many files when zipped are almost as big as the original (a zipped pdf is about 95% of original size). And anyway unzipping has some overhead, that becomes twice when I need also to "Check-in"/Update the file because I need to zip it. So I was thinking of giving to the users the option to choose whether the file type will be zipped or not by providing some meaningful default values. For my experience I would impose the following rules: 1) zip by default: txt, bmp, rtf 2) do not zip by default: jpg, jpeg, Microsoft Office files, Open Office files, png, tif, tiff Could you suggest other file types chosen among the most common or comment on the ones I listed here?

  • strip version from package name using Bash

    - by cd1
    hi, I'm trying to strip the version out of a package name using only Bash. I have one solution but I don't think that's the best one available, so I'd like to know if there's a better way to do it. by better I mean cleaner, easier to understand. suppose I have the string "my-program-1.0" and I want only "my-program". my current solution is: #!/bin/bash PROGRAM_FULL="my-program-1.0" INDEX_OF_LAST_CHARACTER=`awk '{print match($0, "[A-Za-z0-9]-[0-9]")} <<< $PROGRAM_FULL` PROGRAM_NAME=`cut -c -$INDEX_OF_LAST_CHARACTER <<< $PROGRAM_FULL` actually, the "package name" syntax is an RPM file name, if it matters. thanks!

  • Ignoring specific differences in diff

    - by naumcho
    When doing recursive diffs I want to ignore expected differences/translations - is there a way to do that with standard unix tools? E.g. file1: 1 ... 2 /path/to/something/ver1/blah/blah 3 /path/to/something/ver1/blah/blah 4 ... file2: 1 ... 2 /path/to/something/ver2/blah/blah 3 /path/to/something/ver3/blah/blah 4 ... I want to be able to do something like: diff file1 file2 --ignore-transltion "ver1>ver2" This should show only show me that line 3 is different Does anyone know of a good way to do that? I can easily write a perl script to do it but i will end up re-implementing most of the rest of the functionality of 'diff'. Update: My goal is to run this on directories with different versions of the same files with "diff -r" so I can spot unexpected differences in versions.

  • How to get line count from variable (from MYSQL query)?

    - by Mint
    My problematic code: testMYSQL=`mysql -u $mysqlUser -p$mysqlPass -h $mysqlHost --skip-column-names --batch -D $mysqlDB -e "SELECT $select FROM $mysqlTable WHERE nameTXT='test';"` $testMYSQL now contains: test test test Then I do: TEST=$(echo $testMYSQL | wc -l) echo "$TEST" I would of thought that would work, but it doesn't, it returns 1 But if I put this into $testMYSQL: "test\ntest\ntest" it will say 3… Whats going on here? does MYSQL not use new lines? PS, I know I can use a for loop to loop though the lines then count up the lines that way, but I was hoping for a simpler solution like wc

  • Linux How to print all the files with the same prefix after searching for them?

    - by Alyx
    I need to search through a directory which contains many sub directories, each which contain files. The files read as follows question1234_01, where 1234 are random digits and the suffix _01 is the number of messages that contain the prefix, meaning they are apart of the same continuing thread. find . -name 'quest*' | cut -d_ -f1 | awk '{print $1}' | uniq -c | sort -n example output: 1 quest1234 10 quest1523 This searches for all the files then sorts them in order. What I want to do is print all the files which end up having the most occurrences, in my example the one with 10 matches. So it should only output quest1523_01 - 11

  • Creating a Custom Ubuntu Daemon

    - by Chris S
    What's the "correct" way to create a custom daemon in Ubuntu, that will start at boot time and be controllable by Ubuntu's standard daemon start/stop commands? Can I just copy and paste one of the scripts in /etc/init.d or do I need to "register" the daemon somewhere else?

  • How to check an exectuable's path is correct in PHP?

    - by nickf
    I'm writing a setup/installer script for my application, basically just a nice front end to the configuration file. One of the configuration variables is the executable path for mysql. After the user has typed it in (for example: /path/to/mysql-5.0/bin/mysql or just mysql if it is in their system PATH), I want to verify that it is correct. My initial reaction would be to try running it with "--version" to see what comes back. However, I quickly realised this would lead to me writing this line of code: shell_exec($somethingAUserHasEntered . " --version"); ...which is obviously a Very Bad Thing. Now, this is a setup script which is designed for trusted users only, and ones which probably already have relatively high level access to the system, but still I don't think the above solution is something I want to write. Is there a better way to verify the executable path? Perhaps one which doesn't expose a massive security hole?

  • how to search for a term only in non test files

    - by dorelal
    I use ack and I like it. However from time to time I need to search for something in my code base and I want to ignore all the files residing in test directory. Basically all the files which have test in their absolute path should be not included in the search. How do I achieve that? I am willing to have a custom bash script. Something like ack_no_test "application" - search for "application" in all files but ignore files residing in test directory
