Docker Setup

I have setup the docker container to run the model evaluation.

Initial Query

Write a bash script to rename all files of the form "merged_*" to "finished_*". I want to call it by running bash rename.sh /path/to/files.

Query

Write a bash script to rename all files of the form "merged_*" to "finished_*". I want to call it by running bash rename.sh /path/to/files.

Output

Okay, here is a Bash script named `rename.sh` that accomplishes this. **rename.sh:**

**How to use it:** 1. **Save:** Save the code above into a file named `rename.sh`. 2. **Make Executable:** Open your terminal and run `chmod +x rename.sh`. 3. **Run:** Execute the script, providing the path to the directory containing the files as the first argument.

    # Example: If your files are in a subdirectory named 'data_files'
    bash rename.sh ./data_files

    # Example: If your files are in /home/user/project/output
    bash rename.sh /home/user/project/output

    # You can also run it directly if it's in your PATH or current dir
    # ./rename.sh /path/to/files
**Explanation:** 1. **`#!/bin/bash`**: Shebang line, specifies the script should be executed with Bash. 2. **Argument Handling**: Checks if exactly one argument (`$# -ne 1`) is provided. If not, it prints a usage message to standard error (`>&2`) and exits with a status code of 1 (indicating an error). 3. **Directory Validation**: Stores the first argument (`$1`) in `TARGET_DIR` and checks if it's a valid directory (`[ ! -d "$TARGET_DIR" ]`). Exits if it's not. 4. **`cd "$TARGET_DIR"`**: Changes the script's current working directory *to* the target directory. This simplifies the `for` loop and `mv` command as we don't need to prepend the directory path constantly. It includes error checking in case `cd` fails (e.g., due to permissions). 5. **`shopt -s nullglob`**: This shell option is crucial. By default, if a glob pattern (like `merged_*`) doesn't match any files, Bash treats the pattern literally. `nullglob` makes the pattern expand to *nothing* if there are no matches, so the loop simply doesn't run, preventing errors. 6. **`for filename in merged_*; do ... done`**: This loop iterates through all items in the (now current) directory whose names start with `merged_`. 7. **`[ ! -f "$filename" ]`**: Inside the loop, this checks if the found item is a *regular file*. This prevents the script from trying to rename directories or other special files that might match the `merged_*` pattern. 8. **`new_filename="finished_${filename#merged_}"`**: This is the core renaming logic using Bash Parameter Expansion. * `${filename#merged_}` takes the value of `filename` and removes the shortest matching prefix `merged_` from the beginning. * `finished_` is then prepended to the result. 9. **`[ -e "$new_filename" ]`**: This check prevents accidental overwriting. If a file with the *new* name already exists, it prints a warning and skips the rename for that specific file using `continue`. 10. **`mv "$filename" "$new_filename"`**: The actual rename command. Quotes are used around variables to handle filenames with spaces or special characters correctly. Error checking is added. 11. **Counters**: Variables track processed, skipped, and error counts for the summary. 12. **`shopt -u nullglob`**: Resets the `nullglob` option to its default behavior. 13. **Summary**: Prints a report of actions taken. 14. **`exit`**: Exits with 0 if no `mv` errors occurred, or 1 if there were errors during renaming.
