Change File Encoding to utf-8 via vim in a script

Change File Encoding to utf-8 via vim in a script

To change the file encoding to UTF-8 using vim in a script, you can use the following approach. This involves opening the file in vim, setting the encoding to UTF-8, and saving the file. Here's how you can do it:

Method using vim commands in a script:

  1. Create a script file (e.g., convert_encoding.sh) and add the following content:

    #!/bin/bash # Usage: ./convert_encoding.sh filename.txt # Check if filename is provided if [ $# -ne 1 ]; then echo "Usage: ./convert_encoding.sh filename.txt" exit 1 fi # Check if file exists if [ ! -f "$1" ]; then echo "File '$1' not found." exit 1 fi # Open file in vim, set encoding to utf-8, and save vim -c ':set fileencoding=utf-8 | :wq' "$1"

  2. Save the script (convert_encoding.sh) and make it executable:

    chmod +x convert_encoding.sh

  3. Usage:

    To convert the encoding of a file (e.g., example.txt) to UTF-8, you would run:

    ./convert_encoding.sh example.txt

Explanation:

  • Script Description: The script checks if a filename argument is provided and if the file exists. Then, it opens the file in vim, sets the file encoding to UTF-8 (:set fileencoding=utf-8), and saves the file (:wq).

  • Vim Commands:

    • :set fileencoding=utf-8: Sets the file encoding to UTF-8.
    • :wq: Saves the file and exits vim.

  • Error Handling:

    • Checks if the correct number of arguments is provided ($# -ne 1).
    • Checks if the file exists (! -f "$1").

Notes:

  • Ensure that the file you are converting (filename.txt in the example) is originally in a different encoding that vim recognizes and can convert to UTF-8. vim supports various encodings, but the original encoding should be one that vim can detect and convert from.

  • Adjust the script as per your specific requirements, such as handling different encodings or adding more error checks.

This script provides a straightforward way to automate the conversion of file encoding to UTF-8 using vim in a bash script. Adjustments can be made based on your specific needs and environment.

Examples

  1. Change file encoding to UTF-8 using vim

    Description: This query involves using vim commands within a script to convert a file's encoding to UTF-8.

    #!/bin/bash # Edit file in vim and set encoding to UTF-8 vim -c 'set fileencoding=utf-8' -c 'wq' file.txt

    This script opens file.txt in vim, sets the file encoding to UTF-8 (set fileencoding=utf-8), and saves the file (wq).

  2. Convert multiple files to UTF-8 using vim in a loop

    Description: This query involves converting multiple files to UTF-8 encoding using a loop and vim commands in a script.

    #!/bin/bash # List of files to convert files=("file1.txt" "file2.txt" "file3.txt") # Loop through files and convert encoding to UTF-8 using vim for file in "${files[@]}"; do vim -c 'set fileencoding=utf-8' -c 'wq' "$file" done

    This script iterates through each file listed in the files array and converts their encoding to UTF-8 using vim commands.

  3. Batch convert files in a directory to UTF-8 using vim

    Description: This query involves batch converting all files in a directory to UTF-8 encoding using vim commands in a script.

    #!/bin/bash # Directory containing files directory="/path/to/directory" # Convert all files in directory to UTF-8 using vim find "$directory" -type f -exec vim -c 'set fileencoding=utf-8' -c 'wq' {} \;

    This script uses find command to locate all files (-type f) in the specified directory ($directory) and applies vim commands to set their encoding to UTF-8 and save them.

  4. Convert a file to UTF-8 and preserve original file permissions

    Description: This query involves converting a file's encoding to UTF-8 using vim while preserving its original file permissions.

    #!/bin/bash # File to convert file="file.txt" # Save original file permissions permissions=$(stat -c "%a" "$file") # Convert file encoding to UTF-8 using vim vim -c 'set fileencoding=utf-8' -c 'wq' "$file" # Restore original file permissions chmod "$permissions" "$file"

    This script first saves the original file permissions using stat command, converts file.txt to UTF-8 with vim commands, and then restores the original permissions using chmod.

  5. Convert file encoding to UTF-8 and create backup using vim

    Description: This query involves converting a file's encoding to UTF-8 using vim and creating a backup of the original file.

    #!/bin/bash # File to convert file="file.txt" # Create a backup of the original file cp "$file" "$file.bak" # Convert file encoding to UTF-8 using vim vim -c 'set fileencoding=utf-8' -c 'wq' "$file"

    This script first creates a backup (file.txt.bak) of file.txt, then converts file.txt to UTF-8 using vim commands.

  6. Convert file encoding to UTF-8 recursively in subdirectories

    Description: This query involves recursively converting all files in a directory and its subdirectories to UTF-8 using vim commands in a script.

    #!/bin/bash # Root directory to start conversion root_dir="/path/to/root" # Convert all files in root directory and subdirectories to UTF-8 using vim find "$root_dir" -type f -exec vim -c 'set fileencoding=utf-8' -c 'wq' {} \;

    This script uses find command to locate all files (-type f) starting from root_dir and its subdirectories, then applies vim commands to convert their encoding to UTF-8 and save them.

  7. Convert file encoding to UTF-8 and display conversion status

    Description: This query involves converting a file's encoding to UTF-8 using vim and displaying the conversion status in the terminal.

    #!/bin/bash # File to convert file="file.txt" # Convert file encoding to UTF-8 using vim with status message echo "Converting $file to UTF-8..." vim -c 'set fileencoding=utf-8' -c 'wq' "$file" echo "Conversion complete."

    This script prints a message indicating the file being converted (file.txt), performs the conversion using vim commands, and then displays a completion message.

  8. Convert file encoding to UTF-8 with vim and handle errors

    Description: This query involves converting a file's encoding to UTF-8 using vim and handling any errors that may occur during the conversion process.

    #!/bin/bash # File to convert file="file.txt" # Convert file encoding to UTF-8 using vim with error handling if vim -c 'set fileencoding=utf-8' -c 'wq' "$file"; then echo "Conversion successful." else echo "Error: Conversion failed." fi

    This script attempts to convert file.txt to UTF-8 using vim commands and displays a success message if the conversion is successful, or an error message if it fails.

  9. Convert file encoding to UTF-8 and append a timestamp

    Description: This query involves converting a file's encoding to UTF-8 using vim and appending a timestamp to the filename.

    #!/bin/bash # File to convert file="file.txt" # Append timestamp to filename timestamp=$(date +"%Y%m%d%H%M%S") new_file="${file%.*}_${timestamp}.${file##*.}" # Convert file encoding to UTF-8 using vim vim -c 'set fileencoding=utf-8' -c 'wq' "$file" # Rename file with timestamp mv "$file" "$new_file"

    This script appends a timestamp to file.txt before converting it to UTF-8 using vim commands, then renames the file to include the timestamp.

  10. Convert file encoding to UTF-8 using vim and remove BOM

    Description: This query involves converting a file's encoding to UTF-8 using vim and ensuring that any Byte Order Mark (BOM) is removed.

    #!/bin/bash # File to convert file="file.txt" # Convert file encoding to UTF-8 and remove BOM using vim vim -c 'set bomb' -c 'set fileencoding=utf-8' -c 'wq' "$file"

    This script uses vim commands (set bomb and set fileencoding=utf-8) to convert file.txt to UTF-8 and ensure that any existing Byte Order Mark (BOM) is removed during the conversion process.
