bash split string with awk
# Basic syntax:
awk '{split($column_to_split,array_name,"delimiter"); print a[index]}'
# Where:
# - the array_name is usually shortened to a
# - delimiter is the delimiter you want to split the string by
# - index is the index of the string "piece" you want to work with
# Example usage:
# Say you want to split the following string by underscores and print
# the third item:
string_containing_CODE_to_pentagon
echo "string_containing_CODE_to_pentagon" | awk '{split($0,a,"_"); print a[3]}'
--> CODE
# Example usage:
# Say you have input_file.txt that contains two columns and you want to
# split the second column by | and then by _ and then print the second
# string of the final split:
cat file.txt
--> code_1 12|ab_cd|34_ef
code_2 ef_56|gh_78_ij
awk '{split($2, a, "|"); split(a[2],b,"_"); print b[2]}' file.txt
--> cd
