To remove the hyphens from `%%j` which has the value `00-e0-4c-88-88-ee` and change it to `00e04c8888ee` in a batch script using `for /f`, you can use the following approach. Here's a sample script snippet:

```batch
@echo off
setlocal enabledelayedexpansion
set "input=00-e0-4c-88-88-ee"
set "output="
for /f "tokens=1-6 delims=-" %%a in ("%input%") do (
set "output=%%a%%b%%c%%d%%e%%f"
)
echo %output%
endlocal
```

In the above script:

1. First, we enable delayed expansion with `enabledelayedexpansion`.
2. We define the input string with the hyphens.
3. Then, we use `for /f` with `delims=-` to split the input string by hyphens into tokens `%%a` to `%%f`.
4. We concatenate these tokens together to form the string without hyphens, storing the result in `output`.
5. Finally, we echo the resulting string which should be `00e04c8888ee`.

If you are already reading from an external file using `for /f`, you can adjust the script accordingly to process each line from the file similarly. For example, if you have a file named `data.txt` with each line being the string with hyphens, the script would be:

```batch
@echo off
setlocal enabledelayedexpansion
for /f "usebackq delims=" %%i in ("data.txt") do (
set "line=%%i"
set "result="
for /f "tokens=1-6 delims=-" %%a in ("!line!") do (
set "result=%%a%%b%%c%%d%%e%%f"
)
echo !result!
)
endlocal
```

This script reads each line from `data.txt`, processes it to remove hyphens, and then echoes the result.

Deleting specified characters from a variable is equivalent to replacing the specified content with an "empty" character, which is "~:)"

For details, see the fifth floor of the post (you can copy it directly and change the string to what you need). A more general method ~:)

set a=%%j

echo %a:-=%

set a=%%j

echo %a:-=%

The person upstairs, please explain why %a:-=% can remove all "-"? Can you talk about the usage?

The function of %a:x=y% is: replace all "x" contained in variable "a" with "y". In the above example, there are no characters after the equal sign (=), which is replaced with an empty value (not a space), which is equivalent to deleting the "-".

Add a hyphen in delims= in for /f
Then %%j becomes %%j-%%k-%%l-%%m
00e04c8888ee is %%j%%k%%l%%m

It's really that many hands make light work: ) Brother zerocq has another method, haha...
It's a pity that all my points have been used up today: (

High, really high!

I like to use sed for replacements in files

I think there are only these two methods for CMD. Who among the experts can come up with a third one, without using third-party tools?

Too bad I've already used up all my points today: (

I'll help you add some

Haha... Why are the only plus points options 1, 3, 5, 7, 9... Where did the original +2 points option go?
