• Show last command with up arrow on a linux c shell

  - by nunos

  I have implemented a simple linux shell in c. Now, I am adding some features and one I immediately thought about was to be able to show the last commands with the up arrow. Question 1: However, I have no idea how to accomplish this. Do you? Question 2: Any comment on how to store the "history" commands are also appreciated. I suppose something like a queue which allows access to all elements would be a good idea. Am I wrong? Do I have to implement it or is there already some good implementation out there I should know about? Thanks.

• Shell script to process files

  - by Harish

  I need to write a Shell Script to process a huge folder of nearly 20 levels.I have to process each and every file and check which files contain lines like select insert update When I mean line it should take the line till I find a semicolon in that file. I should get a result like this C:/test.java select * from dual C:/test.java select * from test C:/test1.java select * from tester C:/test1.java select * from dual and so on.Right now I have a script to read all the files #!bin/ksh FILE=<FILEPATH to be traversed> TEMPFILE=<Location of Temp file> cd $FILE for f in `find . ! -type d`; do cat $FILE/addedText.txt>>$TEMPFILE/newFile.txt cat $f>>$TEMPFILE/newFile.txt rm $f cat $TEMPFILE/newFile.txt>>$f rm $TEMPFILE/newFile.txt done I have very little knowledge of awk and sed to proceed further in reading each file and achieve what I want to.Can anyone help me in this

• Chrome Extension: How to display tab objects?

  - by Jalleluhah

  I am in the process of designing an extension for Google Chrome that helps to organize tabs (I know, there are many that already exist; that doesn't matter). I wish to open a popup window that will display tabs as objects (i.e., in the same way that it is displayed in the tab bar at the top of the browser). One way of doing this would be to pull various details (ID, Title, URL, etc.) from each tab, create a class and make instantiations of it upon the opening of each tab using these data, but this seems rather convoluted considering that what I want is sitting right there in the tab bar. Is there any simpler way to achieve this? In addition, I have seen several apps that utilize page previews. Is there something in the API that allows direct access to these?

• change extension obfuscate XML file contents

  - by FFish

  I have SlideShowPro, a Flash photo app that loads an XML file with the paths to the images. Now I don't want people to go sniff in the XML file to get to the images. I tried changing the file images.xml to spacer.gif and it seems to work fine. But I would like to know if I would run into any problems changing the extension. btw already used a few techniques to make the images not so accessible, I know there is no bulletproof solution. Obfuscating the XML file is just another trick..

• Call glutinit in a PHP extension

  - by Yijinsei

  Hi guys, I am developing a php extension that require the use of opengl. I tried to initialize the library with glutinit; it works in CLI environment but when I tried on browser it doesn't seem to execute the code. The code is actually executed on the server side. It is part of a process to extract features from an image, and the server will return a list of closest image to the user. I very new to opengl, so I'm not sure what kind of error is this, does anybody have any knowledge with this?

• Firefox extension dev: observing preferences, avoid multiple notifications

  - by Michael

  Let's say my Firefox extension has multiple preferences, but some of them are grouped, like check interval, fail retry interval, destination url. Those are used in just single function. When I subscribe to preference service and add observer, the observe callback will be called for each changed preference, so if by chance user changed all of the settings in group, then I will have to do the same routine for the same subsystem as many times as I have items in that preferences group. It's a great redundancy! What I want is observe to be called just once for group of preferences. Say extensions.myextension.interval1 extensions.myextension.site extensions.myextension.retry so if one or all of those preferences are changed, I receive only 1 notification about it. In other words, no matter how many preferences changed in branch, I want the observe callback to called once.

• Safari extension cookies not recognized/passed

  - by Alex

  I've recently been porting a Chrome extension to Safari, and encountered this kind of error (bug, feature, etc.) So, in global page i have a XMLHTTP request to a secure page which is available only after you login. Example: I simply login using browser - as usually you do on facebook or other secure pages After that, in global page, I load a login-only-available xmlhttp - and it says i'm not logged in it seems that global page somewhat has it's own cookies, so a secure page thinks i'm new ps: in Chrome i can load that page and it thinks i'm acting on behalf of logged in user, so i guess there are some restrictions in Safari pps: i heard there's a Block third-party cookies option in Safari, but even if i checked it to "Never block" it still doesn't work

• Setting variables in shell script by running commands

  - by rajya vardhan

  >cat /tmp/list1 john jack >cat /tmp/list2 smith taylor It is guaranteed that list1 and list2 will have equal number of lines. f(){ i=1 while read line do var1 = `sed -n '$ip' /tmp/list1` var2 = `sed -n '$ip' /tmp/list2` echo $i,$var1,$var2 i=`expr $i+1` echo $i,$var1,$var2 done < $INFILE } So output of f() should be: 1,john,smith 2,jack,taylor But getting 1,p,p 1+1,p,p If i replace following: var1 = `sed -n '$ip' /tmp/list1` var2 = `sed -n '$ip' /tmp/list2` with this: var1=`head -$i /tmp/vip_list|tail -1` var2=`head -$i /tmp/lb_list|tail -1` Then output: 1,john,smith 1,john,smith Not an expert of shell, so please excuse if sounds childish :)

• C# extension method doesn't seem to exist

  - by blahblah

  I can't seem to get the following extension method to be found in another class in the same namespace (MyProject.Util). using System.Collections.Specialized; namespace MyProject.Util { public static class Extensions { public static string Get( this NameValueCollection me, string key, string def ) { return me[key] ?? def; } } } As you can see it's basically another version of foo[bar] ?? baz, but I still don't understand why VS2008 fails to compile telling me that no version of Get takes two arguments. Any ideas?

• Shell script not picking up password file...

  - by BigDogsBarking

  Running the below shell script seems to ignore the password file I'm feeding it. I'm continually prompted for it. If I enter it, the rest of the script goes without a hitch, but as I'm running it via cron, I really need to get it to read from the file... Any suggestions? #!/bin/sh p=$(<password.txt) set -- $p pass_phrase=$1 destination="/var/www/d" cd /var/sl/ for FILE in *.pgp; do FILENAME=${FILE%.pgp} gpg --passphrase "$pass_phrase" --output "$destination/$FILENAME" --decrypt "$FILE" rm -f $FILE done

• Best way to choose a random file from a directory in a shell script

  - by jhs

  What is the best way to choose a random file from a directory in a shell script? Here is my solution in Bash but I would be very interested for a more portable (non-GNU) version for use on Unix proper. dir='some/directory' file=`/bin/ls -1 "$dir" | sort --random-sort | head -1` path=`readlink --canonicalize "$dir/$file"` # Converts to full path echo "The randomly-selected file is: $path" Anybody have any other ideas? Edit: lhunath makes a good point about parsing ls. I guess it comes down to whether you want to be portable or not. If you have the GNU findutils and coreutils then you can do: find "$dir" -maxdepth 1 -mindepth 1 -type f -print0 \ | sort --zero-terminated --random-sort \ | sed 's/\d000.*//g/' Whew, that was fun! Also it matches my question better since I said "random file". Honsetly though, these days it's hard to imagine a Unix system deployed out there having GNU installed but not Perl 5.

• Shell Script - comparing lines of text, deleting matches

  - by SirRatty

  Hi all, I've done some searching for this but cannot find what I'm after, specifically. I have two files: "a.txt", "b.txt". Each contains a list of email addresses, separated by newlines. For all lines in "a.txt", I need to check for a match anywhere in "b.txt". If so, the email address in "a.txt" needs to be removed. (Alternatively, a new file "c.txt" could be created with the output if that is easier.) I'm using Mac OS X, so am looking for a shell script that could help, or pointers to how I'd go about constructing the script. Thanks for any help.

  - by teehoo

  I have the following gifs on my linux system: $ find . -name *.gif ./gifs/02.gif17.gif ./gifs/fit_logo_en.gif ./gifs/halloween_eyes_63.gif ./gifs/importing-pcs.gif ./gifs/portal.gif ./gifs/Sunflower_as_gif_small.gif ./gifs/weird.gif ./gifs2/00p5dr69.gif ./gifs2/iss013e48788.gif ...and so on What I have written is a program that converts GIF files to BMP with the following interface: ./gif2bmp -i inputfile -o outputfile My question is, is it possible to write a one line command using xargs, awk, find etc. to run my program once for each one of these files? Or do I have to write a shell script with a loop?

• How to kill all subprocesses of shell?

  - by depesz

  I'm writing bash script, which does several thing. In the beginning it starts several monitor scripts, each of them runs some other tools. At the end of my main script, I would like to kill all things that spawned from my shell. So, it might looks like this: #!/bin/bash some_monitor1.sh & some_monitor2.sh & some_monitor3.sh & do_some_work ... kill_subprocesses The thing is that most of these monitors spawn their own subprocesses, so doing (for example): killall some_monitor1.sh will not always help. Any other way to handle this situation?

• Shell script for testing

  - by Helltone

  I want a simple testing shell script that launches a program N times in parallel, and saves each different output to a different file. I have made a start that launches the program in parallel and saves the output, but how can I keep only the outputs that are different? Also how can I actually make the echo DONE! indicate the end? #!/bin/bash N=10 for((i=1; j<=$N; ++i)); do ./test > output-$N & done echo DONE!

I even tried doing a get against cnn.com and got no response. any ideas? thanks

• Extension method return using generics

  - by Steven de Salas

  Is it possible to return a generic type using extension methods? For example, I have the following method: // Convenience method to obtain a field within a row (as a double type) public static double GetDouble(this DataRow row, string field) { if (row != null && row.Table.Columns.Contains(field)) { object value = row[field]; if (value != null && value != DBNull.Value) return Convert.ToDouble(value); } return 0; } This is currently used as follows: double value = row.GetDouble("tangible-equity"); but I would like to use the following code: double value = row.Get<double>("tangible-equity"); Is this possible and if so, what would the method look like?

• "set -e" in shell and command substitution

  - by ivant

  In shell scripts set -e is often used to make them more robust by stopping the script when some of the commands executed from the script exits with non-zero exit code. It's usually easy to specify that you don't care about some of the commands succeeding by adding || true at the end. The problem appears when you actually care about the return value, but don't want the script to stop on non-zero return code, for example: output=$(possibly-failing-command) if [ 0 == $? -a -n "$output" ]; then ... else ... fi Here we want to both check the exit code (thus we can't use || true inside of command substitution expression) and get the output. However, if the command in command substitution fails, the whole script stops due to set -e. Is there a clean way to prevent the script from stopping here without unsetting -e and setting it back afterwards?

  - by arav

  I need to call another shell script testarg.sh within my main script. This script testarg.sh has arguments ARG1 ,ARG2, ARG3. I need to call up the below way ./testarg.sh -ARG1 -ARG2 -ARG3 ARG1 and ARG3 argument Variables are mandatory ones. If its not passed to the main script then i quit. ARG2 is an optional one. If the ARG2 variable is not set with value or it's not defined then i need not pass it from main script.So i need to call up the below way ./testarg.sh -ARG1 -ARG3 If the value exist for the ARG2 Varibale then i need to call the below way ./testarg.sh -ARG1 -ARG2 -ARG3 Do i need to have a if else statement for checking the ARG2 variable is empty or null. Is there any other way to do it.
