10 Examples Of Cutting Ascendency Inwards Unix Together With Linux

The cut ascendance inwards UNIX is a squeamish utility plan which allows yous to cutting information from a text file. The Linux cut command allows yous to cutting information yesteryear character, yesteryear champaign or yesteryear column. if used correctly along alongside sed, find, or grep in UNIX, the cut tin produce lots of reporting stuff. For example, yous tin extract columns from a comma separated file or a piping or colon delimited file using cutting command. For example, if yous are entirely interested inwards get-go 2 columns yous tin demo them using this command.  In this Linux cut ascendance tutorial nosotros volition run into unlike options of cutting command, unlike examples of Linux cutting ascendance as well as simply about of import points virtually cutting inwards UNIX.

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

Here is the content of the file for your reference

Original File
trader@asia: /perl truthful cat list-of-smartphones-2014.txt
Model:Company:Price:Camera:4G
IPhone4:Apple:1000$:Yes:Yes
Galaxy:Samsung:900$:Yes:Yes
Optimus:LG:800$:Yes:Yes
Sensation:HTC:400$:Yes:Yes
IPhone4S:Apple:1100:Yes:Yes
N9:Nokia:400:Yes:Yes

How to purpose CUT ascendance inwards Linux

Now, let's run into simply about of the often used examples of cutting ascendance inwards Linux. You volition larn virtually how to extract columns from a text file inwards Linux, extracting columns yesteryear characters, using cut ascendance alongside whatever delimiter e.g. colon or pipe, extracting columns yesteryear the tab character, how to display the get-go column, as well as how to display multiple columns from the text file using cut ascendance inwards Linux.

How to Cut Text yesteryear Columns inwards UNIX

Cutting yesteryear Column is easy, yous get-go require to determine a delimiter, default is tab as well as therefore yous require to specify column let on with -f option,  f stands for a field, for example, cut -f1 file volition display get-go column data. Since our file is colon delimited, nosotros tin purpose a colon every bit a delimiter as well as and therefore extract columns every bit shown inwards the next example:

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

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

Unix Cut yesteryear Characters

In the next event of the cutting ascendance inwards UNIX volition cutting yesteryear characters from 1st to ninth character. yous tin banking concern tally each employment of the output is just nine 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 grapheme is default delimiter for cutting command. as well as "-f" selection is used to cutting yesteryear a delimiter. You tin override delimiter yesteryear providing the "-d" option. Following UNIX or Linux cut command event volition demo you how to separate a employment yesteryear delimiter inwards UNIX.

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

In this event delimiter is a colon i.e. ":" character, specified simply afterward "-d" as well as nosotros convey displayed values from the minute column. If yous desire to display values from third column as well as therefore simply laissez passer iii afterward -f e.g. -f3, similarly for nth column simply laissez passer -fn. See Linux Command Line: Influenza A virus subtype H5N1 consummate Introduction if yous desire to larn to a greater extent than virtually this option.

UNIX cutting +sed command event alongside tab delimiter

To demo yous an event of the cutting ascendance alongside tab delimiter, nosotros require to get-go alter our delimiter from ":" to tab, for that nosotros tin purpose the sed command, which volition supervene upon all colon with \t or tab character. After that, nosotros tin use and as well as therefore nosotros volition apply the cutting ascendance of Linux to extract the get-go column. 

Here is the exact ascendance yous tin purpose 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 grapheme of each employment from the input file.

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

You tin run into that entirely get-go grapheme from each employment is displayed.

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

Sometimes, nosotros require value from the get-go column from a comma separated or colon separated file. that's real slow alongside UNIX/Linux cutting command. define a delimiter as well as specify a column number. hither is an event 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 ascendance inwards Linux

You tin demo to a greater extent than than 1 columns using Linux cutting command. next event volition demo both get-go as well as 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 run into that both column 1 as well as column 2 are displayed together.

Important points on cutting ascendance inwards UNIX as well as Linux

Let's revisit simply about of import things virtually cutting ascendance inwards *NIX operating system. It's 1 of your helpful mates when awk command is non available.

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

2) The default delimiter inwards cutting ascendance is "tab", yous tin alter delimiter alongside the selection "-d" inwards the cutting command.

3) The cutting ascendance inwards Linux allows yous to conduct business office of content yesteryear bytes, yesteryear character, as well as yesteryear champaign or column.

4) The cutting ascendance inwards UNIX or Linux tin function alongside files or yous tin piping it alongside the output of other UNIX/Linux command.

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

6) The cutting -c ascendance selection is used to acquire employment segments yesteryear characters.


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

That's all virtually cut ascendance inwards UNIX as well as Linux. I honey this ascendance for its simplicity inwards power, clever purpose of cutting ascendance is capable of parsing log files, extracting the details yous actually require inwards 1 column as well as they yous tin purpose the ability of Excel to filter as well as kind that every bit per your need. In UNIX yous tin combine the output of the cut command to uniq and sort to filter duplicate as well as impress them inwards sorted order.
