Find and Replace random numeric value with non-numeric value
Can someone tell me how to change the first column in a very large 17k line file from a random 10 digit numeric value to a non numeric value. The format of lines in the file is:
1702938475,SNU022,201004
the first 10 numbers always begin with 170

glgetshaderprecisionformat
GLGETSHADERPRECISION(3G) [FIXME: manual] GLGETSHADERPRECISION(3G)
NAME
glGetShaderPrecisionFormat - retrieve the range and precision for numeric formats supported by the shader compiler
C SPECIFICATION
void glGetShaderPrecisionFormat(GLenum shaderType, GLenum precisionType, GLint *range, GLint *precision);
PARAMETERS
shaderType
Specifies the type of shader whose precision to query. shaderType must be GL_VERTEX_SHADER or GL_FRAGMENT_SHADER.
precisionType
Specifies the numeric format whose precision and range to query.
range
Specifies the address of array of two integers into which encodings of the implementation's numeric range are returned.
precision
Specifies the address of an integer into which the numeric precision of the implementation is written.
DESCRIPTION
glGetShaderPrecisionFormat retrieves the numeric range and precision for the implementation's representation of quantities in different
numeric formats in specified shader type. shaderType specifies the type of shader for which the numeric precision and range is to be
retrieved and must be one of GL_VERTEX_SHADER or GL_FRAGMENT_SHADER. precisionType specifies the numeric format to query and must be one
of GL_LOW_FLOAT, GL_MEDIUM_FLOAT GL_HIGH_FLOAT, GL_LOW_INT, GL_MEDIUM_INT, or GL_HIGH_INT.
range points to an array of two integers into which the format's numeric range will be returned. If min and max are the smallest values
representable in the format, then the values returned are defined to be: range[0] = floor(log2(|min|)) and range[1] = floor(log2(|max|)).
precision specifies the address of an integer into which will be written the log2 value of the number of bits of precision of the format.
If the smallest representable value greater than 1 is 1 + eps, then the integer addressed by precision will contain floor(-log2(eps)).
ERRORS
GL_INVALID_ENUM is generated if shaderType or precisionType is not an accepted value.
