For example, you lot tin hand the sack extract columns from a comma separated file or a piping or colon delimited file using cutting command. For example, if you lot are entirely interested inwards get-go 2 columns you lot tin hand the sack demo them using this command.  In this Linux cut dominance tutorial nosotros volition run into unlike options of cutting command, unlike examples of Linux cutting dominance in addition to around of import points close cutting inwards UNIX.

In gild to demonstrate the ability of cut dominance through diverse examples, nosotros volition next colon delimited text file equally input. This text file contains details of pop smartphones inwards 2011. The file contains five columns i.e. model, company, price, camera, in addition to 4G inwards the same order.

Here is the content of the file for your reference

How to role CUT dominance inwards Linux

Now, let's run into around of the oftentimes used examples of cutting dominance inwards Linux. You volition acquire close how to extract columns from a text file inwards Linux, extracting columns yesteryear characters, using cut dominance amongst whatsoever delimiter e.g. colon or pipe, extracting columns yesteryear the tab character, how to display the get-go column, in addition to how to display multiple columns from the text file using cut dominance inwards Linux.

How to Cut Text yesteryear Columns inwards UNIX

Since our file is colon delimited, nosotros tin hand the sack role a colon equally a delimiter in addition to and hence extract columns equally shown inwards the next example:

$ cutting -d: -f1 list-of-smartphones-2011.txt Model IPhone4 Milky Way Optimus Sensation IPhone4S N9

You tin hand the sack run into that entirely information from get-go column is displayed.

Unix Cut yesteryear Characters

In the next instance of the cutting dominance inwards UNIX volition cutting yesteryear characters from 1st to ninth character. you lot tin hand the sack depository fiscal establishment stand upward for each trouble of the output is precisely ix characters long.

$ cutting -c 1-9 list-of-smartphones-2011.txt Model:Com IPhone4:A Galaxy:Sa Optimus:L Sensation IPhone4S: N9:Nokia:

Unix Cut yesteryear delimiter

The tab graphic symbol is default delimiter for cutting command. in addition to "-f" choice is used to cutting yesteryear a delimiter. You tin hand the sack override delimiter yesteryear providing the "-d" option. Following UNIX or Linux cut command instance volition demo you how to split upward a trouble yesteryear delimiter inwards UNIX.

$ cutting -d: -f2 list-of-smartphones-2011.txt Company Apple Samsung LG HTC Apple Nokia

In this instance delimiter is a colon i.e. ":" character, specified merely later on "-d" in addition to nosotros bring displayed values from the minute column. If you lot desire to display values from third column in addition to hence merely hand iii later on -f e.g. -f3, similarly for nth column merely hand -fn. See Linux Command Line: Influenza A virus subtype H5N1 consummate Introduction if you lot desire to acquire to a greater extent than close this option.

UNIX cutting +sed command instance amongst tab delimiter

To demo you lot an instance of the cutting dominance amongst tab delimiter, nosotros bespeak to get-go modify our delimiter from ":" to tab, for that nosotros tin hand the sack role the sed command, which volition supplant all colon with \t or tab character.

Here is the exact dominance you lot tin hand the sack role to produce that

$ sed 's/:/\t/g' list-of-smartphones-2011.txt | cutting -f 1 Model IPhone4 Milky Way Optimus Sensation IPhone4S N9

How to Cut the First Character of a Line inwards UNIX

Following is an example of the cutting inwards UNIX volition display the get-go graphic symbol of each trouble from the input file.

$ cutting -c 1 list-of-smartphones-2011.txt M I G O south I N

You tin hand the sack run into that entirely get-go graphic symbol from each trouble is displayed.

How to display the get-go column from a delimited file

Sometimes, nosotros bespeak value from the get-go column from a comma separated or colon separated file. that's real tardily amongst UNIX/Linux cutting command. define a delimiter in addition to specify a column number. hither is an instance of UNIX cutting the get-go column.

$ cutting -d: -f1 list-of-smartphones-2011.txt Model IPhone4 Milky Way Optimus Sensation IPhone4S N9

Displaying multiple columns on output using cutting dominance inwards Linux

You tin hand the sack demo to a greater extent than than ane columns using Linux cutting command. next instance volition demo both get-go in addition to minute columns from a file.

$ cutting -d: -f '1 2' list-of-smartphones-2011.txt Model:Company IPhone4:Apple Galaxy:Samsung Optimus:LG Sensation:HTC IPhone4S:Apple N9:Nokia

You tin hand the sack run into that both column 1 in addition to column 2 are displayed together.

Important points on cutting dominance inwards UNIX in addition to Linux

Let's revisit around of import things close cutting dominance inwards *NIX operating system. It's ane of your helpful mates when awk command is non available.

1) The cutting dominance is used to display selected business office of file content inwards UNIX.

2) The default delimiter inwards cutting dominance is "tab", you lot tin hand the sack modify delimiter amongst the choice "-d" inwards the cutting command.

3) The cutting dominance inwards Linux allows you lot to pick out business office of content yesteryear bytes, yesteryear character, in addition to yesteryear plain or column.

5) In UNIX, cutting -d dominance is used to cutting yesteryear a delimiter.

6) The cutting -c dominance choice is used to acquire trouble segments yesteryear characters.


Here is a summary of of import cutting dominance examples inwards Linux:

That's all close cut dominance inwards UNIX in addition to Linux. I dear this dominance for its simplicity inwards power, clever role of cutting dominance is capable of parsing log files, extracting the details you lot actually bespeak inwards ane column in addition to they you lot tin hand the sack role the ability of Excel to filter in addition to kind that equally per your need. In UNIX you lot tin hand the sack combine the output of the cut command to uniq and sort to filter duplicate in addition to impress them inwards sorted order.
