To remove the word immediately following "```" in a file, you can use the sed command with a regular expression to perform the substitution. Here's the command:
sed -E 's/(```)[[:alnum:]]+/\1/g' input_file.txt > output_file.txt
Here's the breakdown of the command:
sed: The command itself -E: Tells sed to use extended regular expressions 's/(```)[[:alnum:]]+/\1/g': The substitution expression s/: Starts the substitution command (````): Matches the three backticks and captures them in a group [[:alnum:]]+: Matches one or more alphanumeric characters /\1/: Replaces the matched pattern with the content of the first captured group (the three backticks) g: Global flag to perform the substitution for all occurrences in each line input_file.txt: The file you want to modify (replace this with the actual filename)
outputfile.txt: Redirects the output to a new file (replace this with the desired output filename) This command will create a new file (outputfile.txt) with the words immediately following "```" removed. If you want to perform the operation in-place (i.e., modify the input file directly), you can use the -i option:
sed -i -E 's/(```)[[:alnum:]]+/\1/g' input_file.txt
This command will modify the input_file.txt directly.
