cut

Print a specific character/field range of each line

$ [command] | cut --[characters|fields]=[1|1,10|1-10|1-|-10]

$ [command] | cut --delimiter="[,]" --[fields]=[1]

$ cut --[characters]=[1] [path/to/file]

cut OPTION... [FILE]...

Print selected parts of lines from each FILE to standard output.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.

-b, --bytes=LIST

select only these bytes

-c, --characters=LIST

select only these characters

-d, --delimiter=DELIM

use DELIM instead of TAB for field delimiter

-f, --fields=LIST

select only these fields; also print any line that contains no delimiter character, unless the -s option is specified

-n

(ignored)

--complement

complement the set of selected bytes, characters or fields

-s, --only-delimited

do not print lines not containing delimiters

--output-delimiter=STRING

use STRING as the output delimiter the default is to use the input delimiter

-z, --zero-terminated

line delimiter is NUL, not newline

--help

display this help and exit

--version

output version information and exit

Use one, and only one of -b, -c or -f. Each LIST is made up of one range, or many ranges separated by commas. Selected input is written in the same order that it is read, and is written exactly once. Each range is one of:

N

N'th byte, character or field, counted from 1

N-

from N'th byte, character or field, to end of line

N-M

from N'th to M'th (included) byte, character or field

-M

from first to M'th (included) byte, character or field
