To remove the second token from each line in a file only if it is not an integer, you can use a combination of bash command-line tools including 'awk' or 'sed', which are efficient for processing large files.
A bash solution optimizing for performance on the command line can parse lines and evaluate the second token effectively, ensuring that only non-integer tokens are removed.
Choosing bash for this repetitive task makes sense due to its native support for text processing and scripting capabilities, suitable for tasks like monthly updates.
Using 'awk', a possible command would be: awk '{if($2!~/^[0-9]+$/) $2=
This achieves the goal of modifying lines in a structured and efficient manner, suitable for extensive files with numerous lines.
