split string in shell

#!/usr/bin/env bash

# There are different method of splitting a string.
# Two of those methods are shown below

# a sample string delimeted by ";"
IN="FirstName=John; LastName=Doe; Email=jd@someone.com"

# First method:
# splits the string on ';' and puts them into an array
person=$(echo $IN | tr ";" "
")

# you can loop through the array
for info in $person
do
    echo "> [$info]"
done



# Second method:
echo "$IN" | cut -d ";" -f 1  # returns the first part
echo "$IN" | cut -d ";" -f 2  # returns the second part

#and so on.

bash split

# 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
