<button> tag is introduced in HTML 4.0. Almost all the new versions of the browsers support this tag.
This tag takes 4 attributes namely:
1. name
2. type
3. disabled
4. value
“type” attribute specifies the type of button. It takes 3 values. They are : Submit, Reset, Button.
If it is a “submit” button and the browser is IE then it submits the text present in between the button start and end tags. All other browsers submit the content of “value” attribute.
To combine multiple text files in Unix we need to use the “cat” command.
Syntax: cat filename1 filename2 filename3 >> newfilename
Example: cat a.txt b.txt >> c.txt
In the above example we are combining the contents of the 2 text files in to a third text file. The new file “c.txt” contains the contents of “a.txt” and then the contents “b.txt”.
If the command “cat b.txt a.txt >> c.txt” is used then the new file contains the contents of “b.txt” first and then the contents of “a.txt”.
We can combine any number of text files to a single file. All we need to do is to specify the file names before the “>>” symbol which is the output redirection operator in Unix.
