.. code-block:: bash

    $ cat text.txt
    This is my cat,
     whose name is Betty.
    This is my dog,
     whose name is Frank.
    This is my fish,
     whose name is George.
    This is my goat,
     whose name is Adam.
    
    Replace text:

    $ pysed -r "name" "surname" text.txt
    This is my cat,
     whose surname is Betty.
    This is my dog,
     whose surname is Frank.
    This is my fish,
     whose surname is George.
    This is my goat,
     whose surname is Adam.

    Replace text in specific lines:
    
    $ pysed -r "name" "surname" 2,4 text.txt
    This is my cat,
     whose surname is Betty.
    This is my dog,
     whose surname is Frank.
    This is my fish,
     whose name is George.
    This is my goat,
     whose name is Adam.
     
    Replace text in specific lines and max:
    
    $ pysed -r "is" "IS" 1,7/1 text.txt
    ThIS is my cat,
     whose surname is Betty.
    This is my dog,
     whose surname is Frank.
    This is my fish,
     whose name is George.
    ThIS is my goat,
     whose name is Adam.

    Add character to the beginning of each line:

    $ pysed -r "^" "# " text.txt
    # This is my cat,
    #  whose name is Betty.
    # This is my dog,
    #  whose name is Frank.
    # This is my fish,
    #  whose name is George.
    # This is my goat,
    #  whose name is Adam.
    
    Add character to the end of each line:
    
    $ pysed -r "$" " #" text.txt

    Find all matching pattern: 

    $ pysed -f "name " text.txt
    name name name name
    
    Find all matching pattern in specific lines: 

    $ pysed -f "name " "" 2,4 text.txt
    name name

    Use the argument "--write" in any case when you want to save the changes:
    
    $ pysed -r "name" "surname" text.txt --write

    
    Use as piping:

    $ echo "This is my cat, whose name is Betty" | pysed -r "cat" "dog"
    This is my dog, whose name is Betty

    $ repl="fish"
    $ echo "This is my cat, whose name is Betty" | pysed -r "cat" $repl
    This is my fish, whose name is Betty
    
    $ echo "This is my cat, whose name is Betty" | pysed -r "[^\W]+" "-"
    - - - -, - - - -
    
    $ echo "This is my cat, whose name is Betty" | pysed -r "is" "IS" 1/1
    ThIS is my cat, whose name is Betty

    $ echo "910a13de57dfbdf6f06675db975f8407" | pysed -r "[^\d+]"
    91013576066759758407

    $ echo "910a13de57dfbdf6f06675db975f8407" | pysed -f "\d+"
    910 13 57 6 06675 975 8407
    
    $ echo "910a13de57dfbdf6f06675db975f8407" | pysed -s "\d+"
    910
    
    $ echo "910a13de57dfbdf6f06675db975f8407" | pysed -s "(\d+)(\w+)" "" 0/1
    910
    
    $ echo "910a13de57dfbdf6f06675db975f8407" | pysed -s "(\d+)(\w+)" "" 0/2
    a13de57dfbdf6f06675db975f8407

    $ echo "The temperature today is at +12 degrees Celsius" | pysed -s ".\d+"
    +12
    
    $ echo "/usr/local/bin" | pysed -r "/local" ""
    /usr/bin

    $ echo "/usr/local/bin" | pysed -r "/LoCal" "" //IGNORECASE
    /usr/bin

    Use with command "find". You can use "find" and "pysed" commands in combination to find 
    and replace text in multiple files. For example:

    $ find . -name *.py -exec pysed -r "lefttext" "righttext" {} --write \;
    
    this command finds 'lefttext' string in all python files and replace it with 'righttext'.
