At the moment I am trying to add a path for ns-2 to my .bashrc file, I have installed the ns-allinone-2.34 but the command ns gives the result: command not found when entered into the shell. Here is what my .bashrc file currently looks like, I edited it using gedit: # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User specific aliases and functions export PATH=/home/michael/ns-allinone-2.34/bin/ns:/home/michael/ns-allinone-2.34/bin/nam:$PATH Can someone please explain why this isn't working or what a possible solution may be? I am using fedora 17. Brian

I doubt this is possible without extensive jail-breaking, but is it at all possible to edit the iPad's (or any iOS device's) hosts file? No. Apps can only modify files within the documents directory, within their own sandbox. This is for security, and ease of installing/uninstalling. So you could only do this on a jailbroken device. tremoloqui The previous answer is correct, but if the effect you are looking for is to redirect HTTP traffic for a domain to another IP there is a way. Since it technically is not answering your question, I have asked and answered the question here: How can I

This is quite a simple question: I just need to open a file (this filename is galfit.feedme). I can view the file with view galfit.feedme when I'm in the directory, but I do not know how to edit this file and then save the edit. How do you do that? Nick Anthony Paruta Normal text editors are nano , or vi . For example: root@user:# nano galfit.feedme or root@user:# vi galfit.feedme Abhishek Gupta For editing use vi galfit.feedme //if user has file editing permissions or sudo vi galfit.feedme //if user doesn't have file editing permissions For inserting Press i //Do required editing For exiting

For example, line number 2 reads: "0" (without quotes). I want to change that 0 to a 1, without changing anything else in the text file. I know what line the values will be on, so all i need to know is how to change that value to another value that I specify. I also will have to to the same with strings, not just numbers. Example: From: 4.7 0 check 0 1 0 0 To: 4.7 1 check 0 1 0 0 Thanks! try this: @ECHO OFF &SETLOCAL SET "file=file" SET /a Line#ToSearch=2 SET "Replacement=0" (FOR /f "tokens=1*delims=:" %%a IN ('findstr /n "^" "%file%"') DO ( SET "Line=%%b" IF %%a equ %Line#ToSearch% SET "Line=

I'm developing a sync adapter. I found this: http://groups.google.com/group/android-developers/msg/85f9304dfcc4e284 In that forum a google employee states: In releases of Android from Eclair through Gingerbread integrated editing of 3rd party contacts is poorly supported. The trick is to insert a data row, "Edit in MyApp", which would take the user to your app and your app would then provide an editor activity. Also, there is no provision in the Contacts UI for creating new contacts in 3rd party accounts. We have fixed those issues in Honeycomb. Now you can specify two activities in your

I have a 300 GB text file that contains genomics data with over 250k records. There are some records with bad data and our genomics program 'Popoolution' allows us to comment out the "bad" records with an asterisk. Our problem is that we cannot find a text editor that will load the data so that we can comment out the bad records. Any suggestions? We have both Windows and Linux boxes. UPDATE: More information The program Popoolution ( https://code.google.com/p/popoolation/ ) crashes when it reaches a "bad" record giving us the line number that we can then comment out. Specifically, we get a

I'm using Oracle APEX and I have a report region in a page that displays columns from a SQL query. I want to add edit buttons to the first column of this report so that the user can click on it and edit/review one of the results. How do I add this edit button? Thanks. Tony Andrews Add a column to the SELECT statement of the report like this: SELECT '' edit_link, -- This is the new column ... Go to the Report Attributes tab. Move the new column EDIT_LINK to the top of the list of columns (if you want it to be first). Click on the pencil and paper icon to the left of the EDIT_LINK alias to open
