The tr command squeezes repeated characters using the -s option followed by the set of characters you want to squeeze. For example, to squeeze repeated spaces into a single space, you would use the following command:
tr -s ' ' < input_file.txt
This command reads from input_file.txt, replaces consecutive spaces with a single space, and outputs the result to the terminal. If you want to save the output to a new file, you can use output redirection:
tr -s ' ' < input_file.txt > output_file.txt
In this case, output_file.txt will contain the text with squeezed spaces.
