In a linux-based system, you can use the grep command to find text that does not contain certain characters. To filter out specific characters, you can use the-E option in the grep command to indicate the extended search mode. For example, if you want to find a text that does not contain all letters, you can enter the following command: ``` grep -E '[[: alnum:]]' file ``` This will find all alphabetic characters in the file and use the-E option to indicate that the extended search mode is used. If you want to find all the numbers, you can enter the following command: ``` grep -E '[[: alnum:]]+' file ``` This will find all the alphabetic characters in the file and use the + option to match consecutive characters. In addition to using the-E option, you can also use the-o option to output the filtered result. For example: ``` grep -E '[[: alnum:]]' file| grep -o '* Unfiltered characters *' ``` This will find all the unfiltered characters in the file and use the grep -o option to output the filtered result.
