I have two files. file1 is executable and file2 is just a text file and I use them frequently but I have to do cd every time to reach the directory.  How can I make file1 universally executable in terminal and how to access the content of file2 irrespective of my location in terminal. Is it possible to add content of file2 in man page so that I can just do man file2.   I think this can be done using /etc/environment but I want to know proper method of doing this.

I thought, "surely someone has asked this question before", and began looking for a duplicate.  is a question with the exact same title, just with a little different punctuation and casing. It was "Jquery vs Javascript" and "jQuery vs. Javascript?". The only difference being the ., ?, and the casing.  Since we now , I propose that when checking for questions with duplicate names, certain punctuation be striped out to prevent the duplicate from occurring in the first place.  As pointed out in the comments, if isn't already, white-space and non-printable characters may want to be removed for duplicate detection as well.

How to set HttpResponse timeout for Android in Java I have created the following function for checking the connection status:  private void checkConnectionStatus() {     HttpClient httpClient = new DefaultHttpClient();      try {       String url = "http://xxx.xxx.xxx.xxx:8000/GaitLink/"                    + strSessionString + "/ConnectionStatus";       Log.d("phobos", "performing get " + url);       HttpGet method = new HttpGet(new URI(url));       HttpResponse response = httpClient.execute(method);        if (response != null) {         String result = getResponse(response.getEntity());         ...

What does "\" mean in math Why does Skynet take prisoners? In the Terminator franchise, extermination camps are often mentioned. But from a machine-logic POV, wouldn't it make more sense to just kill all humans on sight, period? Or herd them into small areas and nuke them? (even today's military electronics are hardened against EMPs and Skynet wouldn't care about the environment.)   IIRC, the reasoning behind ghettoization / concentration camps / extermination camps / gas "showers" is to misdirect or mislead people both inside and outside the country as to what was really going on. But Skynet doesn't have to worry about bad publicity, and can manufacture all the free labor it needs. Is there any in-universe explanation for keeping large groups prisoners?
