I have a problem where I have a large amount of files that I need to scan and return a line and its following line, but only when the following line begins with a string.
String one - line one must begin with 'Bill'
String two - line two must begin with 'Jones'.
If these two criteria are matched, it returns the two lines. Repeat for the whole file.
ie. original file:
I'd want it to return only:
Any ideas? No idea where to begin with this, I only have basic scripting skills with sed/awk etc... At the moment I am using this to get the filename and its following line, but it is giving me too much useless information that I have to strip off with other sed commands.
I guess there's a far more elegant way of getting only the lines I need. Any help would be lovely!
Hi,
Iam calling a C program from a Unix shell script. The (C) program reads encrypted username/password from a text file , decrypts and returns the decrypted string.
Is there any way i can return the decrypted string to Unix shell program.

glgetconvolutionfilter
GLGETCONVOLUTIONFILTER(3G)GLGETCONVOLUTIONFILTER(3G)NAME
glGetConvolutionFilter - get current 1D or 2D convolution filter kernel
C SPECIFICATION
void glGetConvolutionFilter( GLenum target,
GLenum format,
GLenum type,
GLvoid *image )
PARAMETERS
target The filter to be retrieved. Must be one of GL_CONVOLUTION_1D or GL_CONVOLUTION_2D.
format Format of the output image. Must be one of GL_RED, GL_GREEN, GL_BLUE, GL_ALPHA, GL_RGB, GL_BGR, GL_RGBA, GL_BGRA, GL_LUMINANCE, or
GL_LUMINANCE_ALPHA.
type Data type of components in the output image. Symbolic constants GL_UNSIGNED_BYTE, GL_BYTE, GL_BITMAP, GL_UNSIGNED_SHORT, GL_SHORT,
GL_UNSIGNED_INT, GL_INT, GL_FLOAT, GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV, GL_UNSIGNED_SHORT_5_6_5,
GL_UNSIGNED_SHORT_5_6_5_REV, GL_UNSIGNED_SHORT_4_4_4_4, GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1,
GL_UNSIGNED_SHORT_1_5_5_5_REV, GL_UNSIGNED_INT_8_8_8_8, GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, and
GL_UNSIGNED_INT_2_10_10_10_REV are accepted.
image Pointer to storage for the output image.
DESCRIPTION
glGetConvolutionFilter returns the current 1D or 2D convolution filter kernel as an image. The one- or two-dimensional image is placed in
image according to the specifications in format and type. No pixel transfer operations are performed on this image, but the relevant pixel
storage modes are applied.
Color components that are present in format but not included in the internal of the filter are returned as zero. The assignments of
internal color components to the components of format are as follows.
-----------------------------------------
Internal Component Resulting Component
-----------------------------------------
Red Red
Green Green
Blue Blue
Alpha Alpha
Luminance Red
Intensity Red
-----------------------------------------
NOTES
glGetConvolutionFilter is present only if GL_ARB_imaging is returned when glGetString is called with an argument of GL_EXTENSIONS.
The current separable 2D filter must be retrieved with glGetSeparableFilter rather than glGetConvolutionFilter.
ERRORS
GL_INVALID_ENUM is generated if target is not one of the allowable values.
GL_INVALID_ENUM is generated if format is not one of the allowable values.
GL_INVALID_ENUM is generated if type is not one of the allowable values.
GL_INVALID_OPERATION is generated if glGetConvolutionFilter is executed between the execution of glBegin and the corresponding execution of
glEnd.
GL_INVALID_OPERATION is generated if type is one of GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV, GL_UNSIGNED_SHORT_5_6_5, or
GL_UNSIGNED_SHORT_5_6_5_REV and format is not GL_RGB.
GL_INVALID_OPERATION is generated if type is one of GL_UNSIGNED_SHORT_4_4_4_4, GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1,
GL_UNSIGNED_SHORT_1_5_5_5_REV, GL_UNSIGNED_INT_8_8_8_8, GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, or
GL_UNSIGNED_INT_2_10_10_10_REV and format is neither GL_RGBA nor GL_BGRA.
