# The `cut` command
|
|
|
|
The `cut` command lets you remove sections from each line of files. Print selected parts of lines from each FILE to standard output. With no FILE, or when FILE is -, read standard input.
|
|
|
|
### Usage and Examples:
|
|
|
|
1. Selecting specific fields in a file
|
|
```
|
|
cut -d "delimiter" -f (field number) file.txt
|
|
```
|
|
|
|
2. Selecting specific characters:
|
|
```
|
|
cut -c [(k)-(n)/(k),(n)/(n)] filename
|
|
```
|
|
Here, **k** denotes the starting position of the character and **n** denotes the ending position of the character in each line, if _k_ and _n_ are separated by “-” otherwise they are only the position of character in each line from the file taken as an input.
|
|
|
|
3. Selecting specific bytes:
|
|
```
|
|
cut -b 1,2,3 filename //select bytes 1,2 and 3
|
|
cut -b 1-4 filename //select bytes 1 through 4
|
|
cut -b 1- filename //select bytes 1 through the end of file
|
|
cut -b -4 filename //select bytes from the beginning till the 4th byte
|
|
```
|
|
**Tabs and backspaces** are treated like as a character of 1 byte.
|
|
|
|
### Syntax:
|
|
|
|
```
|
|
cut OPTION... [FILE]...
|
|
```
|
|
|
|
