Apologies for the utter triviality of this question, but we all have to start somewhere! I've also tried searching but this question is pretty vague so I didn't (a) really know what to search for or (b) get many relevant hits to what I did search for.
Anyway, I'm in the process of self-teaching... (1 Reply)

Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

GLSHADERSOURCE(3G) OpenGL 3.3 GLSHADERSOURCE(3G) NAME
glShaderSource - Replaces the source code in a shader object C SPECIFICATION
void glShaderSource(GLuint shader, GLsizei count, const GLchar **string, const GLint *length); PARAMETERS
shader Specifies the handle of the shader object whose source code is to be replaced. count Specifies the number of elements in the string and length arrays. string Specifies an array of pointers to strings containing the source code to be loaded into the shader. length Specifies an array of string lengths. DESCRIPTION
glShaderSource sets the source code in shader to the source code in the array of strings specified by string. Any source code previously stored in the shader object is completely replaced. The number of strings in the array is specified by count. If length is NULL, each string is assumed to be null terminated. If length is a value other than NULL, it points to an array containing a string length for each of the corresponding elements of string. Each element in the length array may contain the length of the corresponding string (the null character is not counted as part of the string length) or a value less than 0 to indicate that the string is null terminated. The source code strings are not scanned or parsed at this time; they are simply copied into the specified shader object. NOTES
OpenGL copies the shader source code strings when glShaderSource is called, so an application may free its copy of the source code strings immediately after the function returns. ERRORS
GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL. GL_INVALID_OPERATION is generated if shader is not a shader object. GL_INVALID_VALUE is generated if count is less than 0. ASSOCIATED GETS
