Solving case sensitive problem for xml files in Linux

[danielvasc]

I was facing some issues on my Ubuntu 22.04 server because the .lua files mentioned in my actions.xml file were saved with both uppercase and lowercase letters, and Linux is case-sensitive. As a result, I encountered such problems:

>> Loading vocations
>> Loading items... OTB v2.7.2
>> Loading script systems
>> Using Lua 5.2
>> Loading lua libs

You can imagine the headache it would be to rename each file manually, right?

So, I created a shell script to solve my problem:

#!/bin/bash


# Function to extract the script path from XML lines
get_script_path() {
    local line=$1
    local start_pos=$(expr index "$line" '"')
    local end_pos=$(expr index "${line:$start_pos}" '"')
    echo "${line:$start_pos:$end_pos-1}"
}


# Main script starts here
# Check if the XML file is provided as argument
if [ $# -ne 1 ]; then
    echo "Usage: $0 <actions.xml>"
    exit 1
fi


# Store the XML file path
xml_file=$1


# Check if the XML file exists
if [ ! -f "$xml_file" ]; then
    echo "Error: XML file '$xml_file' not found."
    exit 1
fi


# Loop through each line in the XML file
while read -r line; do
    # Check if the line contains the 'script=' attribute
    if [[ "$line" == *"script=\""* ]]; then
        # Extract the script path from the line
        script_path=$(get_script_path "$line")
        
        # Check if the script file exists
        if [ ! -f "/home/TFS-1.5-Downgrades-8.0/data/actions/scripts/$script_path" ]; then
            echo "Script file '$script_path' not found."
        else
            # Extract the directory and filename from the script path
            dir_path=$(dirname "$script_path")
            file_name=$(basename "$script_path")
            
            # Change directory to the script directory
            cd "/home/TFS-1.5-Downgrades-8.0/data/actions/scripts/$dir_path" || exit
            
            # Rename the script file to match the filename in the XML
            mv "$(ls | grep -i "$file_name")" "$file_name"
            
            # Output success message
            echo "Script file '$script_path' renamed successfully."
        fi
    fi
done < "$xml_file"

This script is designed to read an XML file containing a list of script paths and their corresponding filenames. It iterates through each line of the XML file, extracts the script path, and checks if the corresponding script file exists in a specific directory. If the script file exists, it renames the script file to match the filename specified in the XML. Finally, it outputs a success message for each script file that is successfully renamed.

To run the script, simply navigate to the "data/actions" directory and execute the following command:

./rename_scripts.sh actions.xml

Remember that to execute the script, you need to make it executable. To do this in Linux, simply use the following command:

chmod +x rename_scripts.sh

You can adapt it to any situation by simply modifying some lines in the script where the directory is defined, as in my example: "/home/TFS-1.5-Downgrades-8.0/data/actions/scripts/$script_path".
