Top Forums UNIX for Beginners Questions & Answers Need to find and replace in a file Post 302997764 by RudiC on Friday 19th of May 2017 06:14:41 AM

That specification is not too consistent: It's not clear if any ABC pattern should be matched, or just the one at positions 6 - 8. There's no 120th char position in the input sample, and esp. not 30 onwards. The replacement as well is not 30 char but 10 chars long. Will it always be the rest of the line to be replaced?
To simulate your sample output, try (GNU sed)
Code:
sed '/ABC/ s/./ /94g' file

glsamplemaski

GLSAMPLEMASKI(3G)						   OpenGL Manual						 GLSAMPLEMASKI(3G)

NAME

       glSampleMaski - set the value of a sub-word of the sample mask

C SPECIFICATION

       void glSampleMaski(GLuint maskNumber, GLbitfield mask);

PARAMETERS

       maskNumber
	   Specifies which 32-bit sub-word of the sample mask to update.

       mask
	   Specifies the new value of the mask sub-word.

DESCRIPTION

       glSampleMaski sets one 32-bit sub-word of the multi-word sample mask, GL_SAMPLE_MASK_VALUE.

       maskIndex specifies which 32-bit sub-word of the sample mask to update, and mask specifies the new value to use for that sub-word.
       maskIndex must be less than the value of GL_MAX_SAMPLE_MASK_WORDS. Bit B of mask word M corresponds to sample 32 x M + B.

NOTES

       glSampleMaski is available only if the GL version is 3.2 or greater, or if the ARB_texture_multisample extension is supported.

ERRORS

       GL_INVALID_VALUE is generated if maskIndex is greater than or equal to the value of GL_MAX_SAMPLE_MASK_WORDS.
