Sorting data from a to z

Hi,

Let's say I have these 3 columns;

Code:
NGC1234  6  9
SL899      4  1
NGC1075   8  3
SL709      5  2

And I want to sort the data according to the first column (from a to z) like having them as:

Code:
NGC1075   8  3
NGC1234  6  9
SL709      5  2
SL899      4  1



Can that be done using AWK?

Using awk, I don't know, but you can use sort instead
I created a file named test1 for this example:
Code:
$ cat test1
NGC1234 6 9
SL899 4 1
NGC1075 8 3
SL709 5 2
$ sort test1
NGC1075 8 3
NGC1234 6 9
SL709 5 2
SL899 4 1
$

You can also use sort after a pipe:
Code:
$ awk '{print}' test1 | sort
$ cat test1 | sort

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.
