Bash split string<\/strong> refers to slicing a string into several parts based on a specific symbol, character, or substring as a delimiter. Here, a delimiter<\/strong> is a specific character or sequence of characters used to separate a string. The steps to split a string in Bash are:<\/p>\n

    \n
  1. Initialize a string variable with any sentence or text. You can also read text from any file or user input.<\/li>\n
  2. Choose a separator based on which you want to split the string.<\/li>\n
  3. Read the string and Split it using the IFS variable, readarray<\/strong> command or tr command, etc.<\/li>\n
  4. Store the split-ted words either into an array or into a variable.<\/li>\n
  5. Finally, print split-ted words using loop<\/a> , echo<\/a>, or printf <\/strong>commands.<\/li>\n<\/ol>\n

    You can use the following 8 methods to split strings in Bash:<\/p>\n

      \n
    1. Using IFS<\/strong> variable:\n
      IFS='Delimiter'\nread -a <array_name> <<< <string_variable><\/code><\/pre>\n<\/li>\n
    2. Using “readarray” <\/strong>command:\n
      readarray -d "delimiter" -t <array_name> <<< <string_variable><\/code><\/pre>\n<\/li>\n
    3. Using parameter <\/strong>expansion:\n
      echo "${STRING_VARIABLE#* DELIMITER}"\necho "${STRING_VARIABLE##* DELIMITER}"\necho "${STRING_VARIABLE% DELIMITER*}"\necho "${STRING_VARIABLE%% DELIMITER*}"<\/code><\/pre>\n<\/li>\n
    4. Using positional <\/strong>parameters:\n
      set -- $STRING_VARIABLE<\/code><\/pre>\n<\/li>\n
    5. Using “tr” <\/strong>command:\n
      array_name=($(echo $STRING_VARIABLE | tr "DELIMITER" "REPLACING_DELIMITER"))<\/code><\/pre>\n<\/li>\n
    6. Using “awk” <\/strong>command:\n
      echo "$STRING_VARIABLE" | awk -F ' DELIMITER' '{print $1,$2,$3,...field\u2019s positional value}'<\/code><\/pre>\n<\/li>\n
    7. Using “sed” <\/strong>command:\n
      SPLIT_STRING=$(echo "$STRING_VARIABLE" | sed 's\/DELIMITER\/REPLACING_DELIMITER\/g')<\/code><\/pre>\n<\/li>\n
    8. Using “cut” <\/strong>command:\n
      echo "$STRING_VARIABLE" | cut -d DELIMITER -f FIELD_NUMBER<\/code><\/pre>\n<\/li>\n<\/ol>\n
