Content of variable
I have a variable that contains filenames like this:
variable="file_1.extension<blank>file_2.extension<blank>file_3.extension<blank>file_4.extension and so on"
How can I make filenames to be separated by newline: (I tried Sed but it didn't worked well)
file_1.extension
file_2.extension
file_3.extension
file_4.extension
I don't want another temporary file and want to do this with the variable:
while read filename; do
some stuff
done<< END
$variable
END
Thank you for suggestions!

is this possible?
its kind of like incrementing the value of a number in a variable. but in this case, instead of the value of the variable being a number, it's just contents/strings/characters/alpha-numeric etc. NOT a number.

glutextensionsupported
glutExtensionSupported(3GLUT) GLUT glutExtensionSupported(3GLUT)
NAME
glutExtensionSupported - helps to easily determine whether a given OpenGL extension is supported.
SYNTAX
int glutExtensionSupported(char *extension);
ARGUMENTS
extension Name of OpenGL extension.
DESCRIPTION
glutExtensionSupported helps to easily determine whether a given OpenGL extension is supported or not. The extension parameter names the
extension to query. The supported extensions can also be determined with glGetString(GL_EXTENSIONS), but glutExtensionSupported does the
correct parsing of the returned string.
glutExtensionSupported returns non-zero if the extension is supported, zero if not supported.
There must be a valid current window to call glutExtensionSupported.
glutExtensionSupported only returns information about OpenGL extensions only. This means window system dependent extensions (for example,
GLX extensions) are not reported by glutExtensionSupported.
EXAMPLE
Here is an example of using glutExtensionSupported:
if (!glutExtensionSupported("GL_EXT_texture")) {
fprintf(stderr, "Missing the texture extension!
");
exit(1);
}
Notice that the name argument includes both the GL prefix and the extension family prefix (EXT).
