10 Examples Of Cutting Ascendence Inward Unix In Addition To Linux

The cut ascendence inwards UNIX is a overnice utility programme which allows you lot to cutting information from a text file. The Linux cut command allows you lot to cutting information past times character, past times champaign or past times column. if used correctly along alongside sed, find, or grep in UNIX, the cut tin create lots of reporting stuff. For example, you lot tin extract columns from a comma separated file or a pipage or colon delimited file using cutting command. For example, if you lot are alone interested inwards rootage ii columns you lot tin demo them using this command.  In this Linux cut ascendence tutorial nosotros volition encounter unlike options of cutting command, unlike examples of Linux cutting ascendence in addition to roughly of import points most cutting inwards UNIX.

In social club to demonstrate the ability of cut ascendence 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 v 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

Original File

Galaxy:Samsung:900$:Yes:Yes
Optimus:LG:800$:Yes:Yes

How to purpose CUT ascendence inwards Linux

Now, let's encounter roughly of the oft used examples of cutting ascendence inwards Linux. You volition larn most how to extract columns from a text file inwards Linux, extracting columns past times characters, using cut ascendence alongside whatsoever delimiter e.g. colon or pipe, extracting columns past times the tab character, how to display the rootage column, in addition to how to display multiple columns from the text file using cut ascendence inwards Linux.

How to Cut Text past times Columns inwards UNIX

Cutting past times Column is easy, you lot rootage quest to create upward one's take away heed a delimiter, default is tab in addition to hence you lot quest to specify column divulge with -f option,  f stands for a field, for example, cut -f1 file volition display rootage column data. Since our file is colon delimited, nosotros tin purpose a colon every bit a delimiter in addition to and hence 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 encounter that alone information from rootage column is displayed.

Unix Cut past times Characters

In the next instance of the cutting ascendence inwards UNIX volition cutting past times characters from 1st to ninth character. you lot tin cheque each trouble 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 past times delimiter

The tab grapheme is default delimiter for cutting command. in addition to "-f" selection is used to cutting past times a delimiter. You tin override delimiter past times providing the "-d" option. Following UNIX or Linux cut command instance volition demo you how to divide a trouble past times 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 only subsequently "-d" in addition to nosotros convey displayed values from the minute column. If you lot desire to display values from tertiary column in addition to hence only plow over three subsequently -f e.g. -f3, similarly for nth column only plow over -fn. See Linux Command Line: H5N1 consummate Introduction if you lot desire to larn to a greater extent than most this option.

UNIX cutting +sed command instance alongside tab delimiter

To demo you lot an instance of the cutting ascendence alongside tab delimiter, nosotros quest to rootage alter our delimiter from ":" to tab, for that nosotros tin purpose the sed command, which volition supercede all colon with \t or tab character. After that, nosotros tin use and in addition to hence nosotros volition apply the cutting ascendence of Linux to extract the rootage column. 

Here is the exact ascendence you lot tin purpose to create 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 rootage grapheme of each trouble from the input file.

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

You tin encounter that alone rootage grapheme from each trouble is displayed.

How to display the rootage column from a delimited file

Sometimes, nosotros quest value from the rootage column from a comma separated or colon separated file. that's rattling slow alongside UNIX/Linux cutting command. define a delimiter in addition to specify a column number. hither is an instance of UNIX cutting the rootage column.

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

Displaying multiple columns on output using cutting ascendence inwards Linux

You tin demo to a greater extent than than ane columns using Linux cutting command. next instance volition demo both rootage 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 encounter that both column 1 in addition to column 2 are displayed together.

Important points on cutting ascendence inwards UNIX in addition to Linux

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

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

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

3) The cutting ascendence inwards Linux allows you lot to pick out business office of content past times bytes, past times character, in addition to past times champaign or column.

4) The cutting ascendence inwards UNIX or Linux tin function alongside files or you lot tin pipage it alongside the output of other UNIX/Linux command.

5) In UNIX, cutting -d ascendence is used to cutting past times a delimiter.

6) The cutting -c ascendence selection is used to acquire trouble segments past times characters.


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

That's all most cut ascendence inwards UNIX in addition to Linux. I dearest this ascendence for its simplicity inwards power, clever purpose of cutting ascendence is capable of parsing log files, extracting the details you lot actually quest inwards ane column in addition to they you lot tin purpose the ability of Excel to filter in addition to form that every bit per your need. In UNIX you lot tin combine the output of the cut command to uniq and sort to filter duplicate in addition to impress them inwards sorted order.
