These scripts and commands are used to convert various image files to TGA format, with options to handle different file types (PCX, JPG, JPEG) and color spaces. They use tools like wal2tga, convert, and find to automate the conversion process in Windows and Bash environments.

Code Breakdown

Windows Script

for /r %%v in (*.wal) do "Z:\planet_quake_data\tools\Wal2TGA\wal2tga copy.exe" "%%v" "%%~dpv%%~nv.tga"

• This is a Windows batch script that loops through all files with the .wal extension in the current directory and its subdirectories (/r option).
• For each file, it runs the wal2tga copy.exe executable from the specified path, passing the file path (%%v) and a new TGA file path generated by combining the original file's directory path (%%~dpv) and name (%%~nv) with a .tga extension.

Windows Script (Alternative)

for /r %%v in (*.pcx or *.jpg or *.jpeg) do convert -colorspace RGB "%%v" "%%~dpv%%~nv.tga" ; done

• This script is similar to the previous one but loops through files with the .pcx, .jpg, and .jpeg extensions.
• For each file, it runs the convert command from ImageMagick, converting the file to RGB color space and saving it as a new TGA file in the same directory.

Bash Script

for i in $(find. -iname '*.pcx' -o -iname '*.jpg' -o -iname '*.jpeg' -o -iname '*.tga'); \
do if [! -f "${i%.*}.tga" ]; \
then convert -colorspace RGB "$i" "${i%.*}.tga"; \
fi; \
done;

• This script uses find to search for files with the .pcx, .jpg, .jpeg, and .tga extensions in the current directory and its subdirectories (.).
• For each file, it checks if a corresponding TGA file with the same name but different extension exists. If not, it runs the convert command from ImageMagick, converting the file to RGB color space and saving it as a new TGA file in the same directory.

Single Command Example

convert -colorspace RGB pak0.pk3dir/models/deadbods/dude/dead1.pcx pak0.pk3dir/models/deadbods/dude/dead1.tga

• This is a single command that converts a specific PCX file to a TGA file using the convert command from ImageMagick.
