AWK is a effective, sample-matching programming language that will work in the command line to locate various styles in command outputs and files.

We can contemplate AWK an enhancement in excess of Sed since it features extra characteristics, together with arrays, variables, loops, and superior old, regular expressions.

In this tutorial, we will rapidly examine how you can use many delimiters in an AWK command. Ahead of we carry on, please notice that this tutorial is not a beginner’s guide to AWK, nor did I intend it as these types of.

You should refer to the pursuing source if you will need a beginner’s guideline to AWK.

How to Use AWK on Linux

What are Delimiters?

I am guaranteed that, considering the fact that you are taking the time to go through this post, you are acquainted with the principle of delimiters. But it does not harm to recap, so let us do that now:

In a nutshell, delimiters are a sequence of characters utilized to independent string textual content values. There are various widespread types of delimiters that incorporate:

Name Symbol
Comma ,
Colon :
Semi-Colon
Period .
Pipe |
Backslash
Slash /
Parenthesis ( )
Curly Braces
Sq. Brackets [ ]
Space

AWK RegEx Discipline Separator

The AWK Area Separator (FS) is utilised to specify and management how AWK splits a file into many fields. Also, it can acknowledge a solitary character of a common expression. The moment you specify a regular expression as the price for the FS, AWK scans the enter values for the sequence of figures set in the frequent expression.

We are going to implement the performance of AWK to settle for Common Expression values in the industry separator to link several delimiters.

Use Many Delimiters

To illustrate how to independent making use of various delimiters in AWK, I will use a very simple illustration to present you how to use this functionality.

Suppose you have a file with data as follows:

/org/gnone/desktop/interface:proven:Apr17 16.59.09|org.gnome.Terminal.desktop[1099]

From the higher than file, we desire to get the output identical to the just one demonstrated underneath:

org/gnome/desktop/interface proven Apr 17 16:59.09 org.gnome.Terminal.desktop[1099]

To different the file making use of the a variety of delimiters—in this situation, a colon, house, and a pipe—we can use a command as revealed underneath:

awk -F‘[: |]’ ‘print $1, $2, $3, $4, $5, $6’ consumer.log

The earlier mentioned command outputs the data as revealed below:

As you can see, you can mix additional than 1 delimiter in the AWK subject separator to get distinct information.

Summary

In this quick guideline, we discussed making use of AWK to different several delimiters in an enter file.
