Alright, I am sure this is a laughable question, but I don't know so I am going to ask anyway.

Hello All,
I have to write a shell script and use it in informatica. The script has to perform below actions:
The script gets executed from edw user.
Through the script, a DT folder has to be created under edw_sca user.
Is this scenario possible through a SHELL script or not.

The `bash` below uses the oldest folder in the specified directory and logs it. The goes though an analysis process and creates a log. My problem is that if there are 3 folders in the directory folder1,folder2,folder3, the bash is using folder2 for the analysis eventhough folder1 is the oldest... (0 Replies)
I am trying to create subdirectories in each folder in /home/cmccabe/Desktop/NGS/test/*. When I use echo I can see each folder in the directory, but I can not seem to add the commented out portion in bold.

In the bash below the oldest folder in a directory is selected. If there are 3folders in the directory /home/cmccabe/Desktop/NGS/test and nothing is done to them (ie. no files deleted, renamed) then the bash correctly identifies f1 as the oldest. However, if something is done to the folder then... (4 Replies)
I am trying to use bash to automate the scan of a specific directory using clamav. Having this in place is a network requirement. The below is an attempt to:

In the below I am trying to create a parent directory using the R_2019 line from f1 if what above it is not empty.
I then create sub-directories under each parent if there is a match between $2 of f1 and $2. Inside each sub-folder the matching paths in $3 and $4 in f2are printed. If there is no... (2 Replies)

glstencilfunc
GLSTENCILFUNC(3G)GLSTENCILFUNC(3G)NAME
glStencilFunc - set function and reference value for stencil testing
C SPECIFICATION
void glStencilFunc( GLenum func,
GLint ref,
GLuint mask )
PARAMETERS
func Specifies the test function. Eight tokens are valid: GL_NEVER, GL_LESS, GL_LEQUAL, GL_GREATER, GL_GEQUAL, GL_EQUAL, GL_NOTEQUAL, and
GL_ALWAYS. The initial value is GL_ALWAYS.
ref Specifies the reference value for the stencil test. ref is clamped to the range [0,2n-1], where n is the number of bitplanes in the
stencil buffer. The initial value is 0.
mask Specifies a mask that is ANDed with both the reference value and the stored stencil value when the test is done. The initial value is
all 1's.
DESCRIPTION
Stenciling, like depth-buffering, enables and disables drawing on a per-pixel basis. You draw into the stencil planes using GL drawing
primitives, then render geometry and images, using the stencil planes to mask out portions of the screen. Stenciling is typically used in
multipass rendering algorithms to achieve special effects, such as decals, outlining, and constructive solid geometry rendering.
The stencil test conditionally eliminates a pixel based on the outcome of a comparison between the reference value and the value in the
stencil buffer. To enable and disable the test, call glEnable and glDisable with argument GL_STENCIL_TEST. To specify actions based on
the outcome of the stencil test, call glStencilOp.
func is a symbolic constant that determines the stencil comparison function. It accepts one of eight values, shown in the following list.
ref is an integer reference value that is used in the stencil comparison. It is clamped to the range [0,2n-1], where n is the number of
bitplanes in the stencil buffer. mask is bitwise ANDed with both the reference value and the stored stencil value, with the ANDed values
participating in the comparison.
If stencil represents the value stored in the corresponding stencil buffer location, the following list shows the effect of each comparison
function that can be specified by func. Only if the comparison succeeds is the pixel passed through to the next stage in the rasterization
process (see glStencilOp). All tests treat stencil values as unsigned integers in the range [0,2n-1], where n is the number of bitplanes
in the stencil buffer.
The following values are accepted by func:
GL_NEVER Always fails.
GL_LESS Passes if ( ref & mask ) < ( stencil & mask ).
GL_LEQUAL Passes if ( ref & mask ) <= ( stencil & mask ).
GL_GREATER Passes if ( ref & mask ) > ( stencil & mask ).
GL_GEQUAL Passes if ( ref & mask ) >= ( stencil & mask ).
GL_EQUAL Passes if ( ref & mask ) = ( stencil & mask ).
GL_NOTEQUAL Passes if ( ref & mask ) != ( stencil & mask ).
GL_ALWAYS Always passes.
NOTES
Initially, the stencil test is disabled. If there is no stencil buffer, no stencil modification can occur and it is as if the stencil test
always passes.
ERRORS
GL_INVALID_ENUM is generated if func is not one of the eight accepted values.
GL_INVALID_OPERATION is generated if glStencilFunc is executed between the execution of glBegin and the corresponding execution of glEnd.
