The cut ascendance inwards UNIX is a prissy utility plan which allows you lot to cutting information from a text file. The Linux cut command allows you lot to cutting information yesteryear character, yesteryear plain or yesteryear column. if used correctly along amongst 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 piping or colon delimited file using cutting command. For example, if you lot are alone interested inwards showtime 2 columns you lot tin exhibit them using this command.  In this Linux cut ascendance tutorial nosotros volition run into dissimilar options of cutting command, dissimilar examples of Linux cutting ascendance in addition to around of import points close cutting inwards UNIX.

In gild to demonstrate the ability of cut ascendance 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 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

How to role CUT ascendance inwards Linux

Now, let's run into around of the oft used examples of cutting ascendance inwards Linux. You volition acquire close how to extract columns from a text file inwards Linux, extracting columns yesteryear characters, using cut ascendance amongst whatever delimiter e.g. colon or pipe, extracting columns yesteryear the tab character, how to display the showtime column, in addition to 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, you lot showtime require to create upwards one's hear a delimiter, default is tab thence you lot require to specify column release with -f option,  f stands for a field, for example, cut -f1 file volition display showtime column data. Since our file is colon delimited, nosotros tin role a colon equally a delimiter in addition to thence 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 run into that alone information from showtime 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. you lot tin cheque each trouble of the output is precisely 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. in addition to "-f" choice is used to cutting yesteryear a delimiter. You tin override delimiter yesteryear providing the "-d" option. Following UNIX or Linux cut command event volition exhibit you how to carve upwards a trouble 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 later "-d" in addition to nosotros accept displayed values from the minute column. If you lot desire to display values from tertiary column thence simply plough over three later -f e.g. -f3, similarly for nth column simply plough over -fn. See Linux Command Line: H5N1 consummate Introduction if you lot desire to acquire to a greater extent than close this option.

UNIX cutting +sed command event amongst tab delimiter

To exhibit you lot an event of the cutting ascendance amongst tab delimiter, nosotros require to showtime alter our delimiter from ":" to tab, for that nosotros tin role the sed command, which volition supervene upon all colon with \t or tab character. After that, nosotros tin use and thence nosotros volition apply the cutting ascendance of Linux to extract the showtime column. 

Here is the exact ascendance you lot tin role 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 showtime grapheme of each trouble from the input file.

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

You tin run into that alone showtime grapheme from each trouble is displayed.

How to display the showtime column from a delimited file

Sometimes, nosotros require value from the showtime column from a comma separated or colon separated file. that's rattling slow amongst UNIX/Linux cutting command. define a delimiter in addition to specify a column number. hither is an event of UNIX cutting the showtime 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 exhibit to a greater extent than than 1 columns using Linux cutting command. next event volition exhibit both showtime 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 run into that both column 1 in addition to column 2 are displayed together.

Important points on cutting ascendance inwards UNIX in addition to Linux

Let's revisit around of import things close 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", you lot tin alter delimiter amongst the choice "-d" inwards the cutting command.

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

4) The cutting ascendance inwards UNIX or Linux tin live amongst files or you lot tin piping it amongst 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 choice is used to acquire trouble segments yesteryear characters.


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

That's all close cut ascendance inwards UNIX in addition to Linux. I honey this ascendance for its simplicity inwards power, clever role of cutting ascendance is capable of parsing log files, extracting the details you lot actually require inwards 1 column in addition to they you lot tin role the ability of Excel to filter in addition to form that equally 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.
