Using cut
To use the cut
command, you must specify which portion of your input you wish to retain. Only the portions of your input you specify will be output. In order to specify the portion of your input you wish to keep, you need to use either the -c
or the -f
argument.
The -c
argument allows you to specify a range of characters which you would like to retain.
The -f
argument allows you to specify a range of fields you would like to retain. By default, the tab character is the default delimiter of cut
, but you can set a different delimiter using the -d
argument.
With either the -c
or the -f
argument, you specify the range using one of four options:
N
: Retains only the N-th character or field (counted from 1).N-
: Retains all characters or fields from the N-th to the end of the line.N-M
: Retains all characters or fields from the N-th to the M-th.-M
: Retains all characters or fields from the first to the M-th.
Examples
Retain only the 3rd field (fields in the input are delimited by tabs):
cut -f 3
Retain only the first four characters:
cut -c -4
Retain all but the first character:
cut -c 2-
Retain only the 2nd, 3rd and 4th fields (fields in the input are delimited by “|”):
cut -f 2-4 -d "|"
