Parse a line of pairs of delimited string and construct new command

 To parse a line of pairs of delimited strings and construct a new command, you can use a scripting language like Python. I'll provide a Python example to illustrate how to do this. Suppose you have a line of pairs of delimited strings, where each pair is separated by a delimiter, and the strings within each pair are separated by another delimiter. You want to construct a new command from these pairs.

Here's an example in Python:

```python

# Sample input line with pairs of delimited strings

input_line = "name=John,age=30;city=New York,occupation=Engineer"

# Split the input line into pairs using the first delimiter

pair_strings = input_line.split(';')

# Initialize an empty dictionary to store the pairs

pair_dict = {}

# Parse each pair and construct the dictionary

for pair_string in pair_strings:

    key_value_pairs = pair_string.split(',')

    for key_value in key_value_pairs:

        key, value = key_value.split('=')

        pair_dict[key] = value

# Construct the new command using the parsed pairs

command = f"command {pair_dict['name']} {pair_dict['age']} {pair_dict['city']} {pair_dict['occupation']}"

# Print the constructed command

print(command)

```

In this example, we first split the input line into pairs using the ';' delimiter. Then, we iterate through each pair, split it into key-value pairs using the ',' delimiter, and construct a dictionary. Finally, we construct a new command using the values from the dictionary.

This is a simple example, and you can adapt it to your specific input format and desired output format. If you're working in a different programming language, the general approach would be similar, but the syntax may vary.
