Why I use long parameter names in scripts, such as `--force` instead of `-f`.
---
The other day, [I posted about a script I'd written][0] that found the longest commit message in a repository.
As I couldn't find a native way to do this with Git, the script loops over each commit in the repository, calculates its length and stores the length and commit SHA in a file.
The lines in the file are sorted so the longest commit is first.
Whilst I commonly use short parameters, such as `git add -p` when typing commands, in scripts, I prefer to use the equivalent longer parameters, where possible.
For example, in the script, I execute this command to sort the lines:
```bash
sort "${result_file}" --reverse --numeric-sort --output "${result_file}"
```
This could be re-written as:
```bash
sort "${result_file}" -rn -o "${result_file}"
```
Whilst the original is more verbose and longer to type, I prefer its verbosity which makes it easier for me or others to read and understand in the future.
