This will do it:
   

     echo &quot;Hi, today is $(date)&quot;

Date time will take in an arbitrary format string.

    &gt; date +&quot;Hi, today is - %a %b %e %H:%M:%S %Z %Y&quot;
      Hi, today is - Thu Feb 2 03:28: CET 2012


    echo Hello there, today is `date`

You can also format the output of date using modifiers like:

    echo Hello there, today is `date +%D`
See `man date` for a complete list of the modifiers.

Backtick will do the trick:

    echo &quot;Hi, today is&quot; `date`

For this particular problem, mimisbrunnr&#39;s solution is the right way to go.  For the general question of how to append data to an echo, some common techniques are:
&lt;pre&gt;
$ echo &#39;Hi, today is &#39; | tr -d &#39;\012&#39;; date
Hi, today is Wed Feb  1 18:11:40 MST 2012
$ echo -n &#39;Hi, today is &#39;; date
Hi, today is Wed Feb  1 18:11:43 MST 2012
$ printf &#39;Hi, today is &#39;; date
Hi, today is Wed Feb  1 18:11:48 MST 2012
&lt;/pre&gt;

I am trying to understand how Android launches applications. The question is how (and why) does the Zygote fork a new Dalvik VM?  I do not understand why it is not possible to run multiple applications in the same Dalvik VM.

This might be the least important Scala question ever, but it&#39;s bothering me.  How would I generate a list of n random number.  What I have so far:

    def n_rands(n : Int) = {
     val r = new scala.util.Random
     1 to n map { _ =&gt; r.nextInt(100) } 
    }

Which works, but doesn&#39;t look very Scalarific to me.  I&#39;m open to suggestions.

**EDIT**

Not because it&#39;s relevant so much as it&#39;s amusing and obvious in retrospect, the following looks like it works:

    1 to 20 map r.nextInt

But the index of each entry in the returned list is also the upper bound of that last.  The first number must be less than 1, the second less than 2, and so on.  I ran it three or four times and noticed &quot;Hmmm, the result always starts with 0...&quot;

Basically I want to have the terminal output a message followed by the date and time, like &quot;Hi, today is -dateandtime-&quot;.

So echo can accomplish the first bit, and date can accomplish the last, but only separately, how can I put them together (in one command) so they output together.

Like

echo hello there

-new command-

date

Does it, but not in one line. Is pipelining the answer?

Hi I want to create a cron expression excluding saturday and sunday.


How to skip saturday and sunday in a cron expression?

So I typically run this command a lot: 

&gt; ssh -L 5901:myUser@computer.myHost.edu:5901

I use it to do VNC over SSH. 

How do I convert that command into something that will work in a ~/.ssh/config file? 

ex: 

    host yam
    	HostName yam.myHost.edu
    	User myUserName

all I want to do is type: 

    ssh yam

And have it open a SSH shell with a local listen port, and a remote port forwarded to it. 

Suggestions?

If I have a custom shell script or programs, that I created myself or downloaded from the web, and I want to be able to execute this from the CLI, is there the standard location to put this in Linux/Unix directory structure?

    /usr/bin ?
    /usr/local/bin ?
    /usr/lib ?
    /usr/sbin ?
    /bin ?
    /sbin ?
    /var ?

I usually put it under my ~/bin folder and put it in PATH, but it doesn&#39;t seem clean. And everytime I downloaded a new program, I have to put it in the PATH again.

Let&#39;s say that I have a date in R and it&#39;s formatted as follows.

       date      
    2012-02-01 
    2012-02-01
    2012-02-02

Is there any way in R to add another column with the day of the week associated with the date? The dataset is really large, so it would not make sense to go through manually and make the changes.

    df = data.frame(date=c(&quot;2012-02-01&quot;, &quot;2012-02-01&quot;, &quot;2012-02-02&quot;)) 

So after adding the days, it would end up looking like:

       date       day
    2012-02-01   Wednesday
    2012-02-01   Wednesday
    2012-02-02   Thursday

Is this possible? Can anyone point me to a package that will allow me to do this?
Just trying to automatically generate the day by the date.

How can I list git branches showing and sorting by their last commits&#39; dates?

I&#39;ve found [this](http://www.commandlinefu.com/commands/view/2345/show-git-branches-by-date-useful-for-showing-active-branches):

    for k in `git branch | sed s/^..//`; do
        echo -e `git log -1 --pretty=format:&quot;%Cgreen%ci %Cblue%cr%Creset&quot; &quot;$k&quot;`\\t&quot;$k&quot;;
    done | sort -r

I&#39;d expect plain git to have this feature. Does it?

I also found `git show-branch --date-order` but the output is something different.

I am having the following problem in Java (I see some people are having
a similar problem in JavaScript but I&#39;m using Java)

    System.out.println(new Date().getYear());
    System.out.println(new GregorianCalendar().getTime().getYear());
    System.out.println(this.sale.getSaleDate().getYear());
    System.out.println(this.sale.getSaleDate().getMonth());
    System.out.println(this.sale.getSaleDate().getDate());

returns

    I/System.out( 4274): 112
    I/System.out( 4274): 112

I don&#39;t understand the 112 bit which I thought would have been 2012.
What&#39;s going on? Is the
`java.util.Date` class unusable? I am storing this as a field in several
of my classes to store a date and time. What should I do?

*Using JPA 2 with EclipseLink implementation.*

I&#39;m trying to build a dynamic query which should bring me some records persisted after a given date.

    CriteriaBuilder builder = em.getCriteriaBuilder();
    CriteriaQuery&lt;Event&gt; criteria = builder.createQuery(Event.class);
    Root&lt;Event&gt; root = criteria.from(Event.class);
    criteria.select(root);
    criteria.distinct(true);
    List&lt;Predicate&gt; predicates = new ArrayList&lt;Predicate&gt;();
    //...
    if (dateLimit != null){
        ParameterExpression&lt;Date&gt; param = builder.parameter(Date.class, &quot;dateLimit&quot;);
        predicates.add(builder.lessThanOrEqualTo(root.get(&quot;dateCreated&quot;), param));
    }

`lessThanOrEqualTo()` and `le()` are the only two methods in the API which look like may help me in this case. This warning is thrown by the eclipse though:

    Bound mismatch: The generic method lessThanOrEqualTo(Expression&lt;? extends Y&gt;, Expression&lt;? extends Y&gt;)
    of type CriteriaBuilder is not applicable for the arguments (Path&lt;Object&gt;, ParameterExpression&lt;Date&gt;).
    The inferred type Object is not a valid substitute for the bounded parameter
    &lt;Y extends Comparable&lt;? super Y&gt;&gt;

I can imagine that I&#39;m not taking the correct approach for this problem but I can&#39;t find anywhere some tips or pointers for a possible solution.

I need to see all of the `POST` results that are submitted to the server for testing.

What would be an example of how I can create a new file to submit to that will echo out all of the fields which were submitted with that form?

It&#39;s dynamic, so some fields may have a name/ID of `field1, field2, field3`, etc.


How do I print all POST results when a form is submitted?

Yes, I have googled this question and even referred to my textbook (PHP by Don Gosselin) but I seriously can&#39;t seem to understand the explanation.

From my understanding:

&gt; echo = shows the final result of a function
&gt; 
&gt; return = returns the value from a function

I applied both `echo` and `return` in the following functions I can&#39;t see the difference or the &#39;effectiveness&#39; of using `return` instead of `echo`.

    &lt;?php
    echo &quot;&lt;h1 style=&#39;font-family:Helvetica; color:red&#39;&gt;Using &lt;em&gt;echo&lt;/em&gt;&lt;/h1&gt;&quot;;
    function add1($x, $y){
    	$total = $x + $y;
    	echo $total;
    }
    echo &quot;&lt;p&gt;2 + 2 = &quot;, add1(2, 2), &quot;&lt;/p&gt;&quot;;
    
    echo &quot;&lt;h1 style=&#39;font-family:Helvetica; color:red&#39;&gt;Using &lt;em&gt;return&lt;/em&gt;&lt;/h1&gt;&quot;;
    function add2($x, $y){
    	$total = $x + $y;
    	return $total;
    }
    echo &quot;&lt;p&gt;2 + 2 = &quot;, add2(2, 2), &quot;&lt;/p&gt;&quot;;
    
    ?&gt;

Both display the result!
What am I not understanding?

How can I echo the whole content of a .html file in PHP?

I&#39;m trying to use the result of `ls` in other commands (e.g. echo, rsync):

    all:
        &lt;Building, creating some .tgz files - removed for clarity&gt;
    	FILES = $(shell ls)
    	echo $(FILES)

But I get:

    make
    FILES = Makefile file1.tgz file2.tgz file3.tgz
    make: FILES: No such file or directory
    make: *** [all] Error 1

I&#39;ve tried using `echo $$FILES`, `echo ${FILES}` and `echo $(FILES)`, with no luck.

How to use shell commands in Makefile

I am trying to automate the addition of a repository source in my arch&#39;s pacman.conf file but using the `echo` command in my shell script.  However, it fails like this:-

    sudo echo &quot;[archlinuxfr]&quot; &gt;&gt; /etc/pacman.conf
    sudo echo &quot;Server = http://repo.archlinux.fr/\$arch&quot; &gt;&gt; /etc/pacman.conf
    sudo echo &quot; &quot; &gt;&gt; /etc/pacman.conf
    
    -bash: /etc/pacman.conf: Permission denied

If I make changes to /etc/pacman.conf manually using vim, by doing

    sudo vim /etc/pacman.conf

and quiting vim with `:wq`, everything works fine and my pacman.conf has been manually updated without &quot;Permission denied&quot; complaints.

Why is this so? And how do I get `sudo echo` to work? (btw, I tried using `sudo cat` too but that failed with Permission denied as well)
