rozdzielenie bash

# Basic syntax:
cut -d "delimeter" -f split_number your_file
# Where:
#	- -d specifies the delimeter to split by
#	- -f specifies which element to return after splitting
# Note, if running this in a bash script, use syntax like:
"$(cut -d ',' -f split_number <<<$variable_to_split)"

# Note, there are lots of ways of doing this, e.g. with awk:
awk -F delimiter '{print $split_number}' your_file
# Where:
#	- -F specifies the field delimiter

# Note, awk also has a split function which has this syntax:
awk '{split($column, a, "delimiter"); action_after_split }' your_file
# Where:
#	- the column is the column to be split (awk uses whitespace to determine
#		columns by default)
#	- a is an array variable which will store the contents of the split
#	- delimiter is the delimiter by which to split the column

# Example usage:
# Say you have a file with this line:
my	file	with	fields_to_split
# You can print "to" with:
awk '{split($4, a, "_"); print a[2] }' your_file
--> to
