Hi,
Excuse my ignorance here - I'm a networks man and my knowledge of all things unix is somewhat limited.
We have a very large file (/var/tmp/mond.log) that we need to zero - does the "cat /dev/null > /var/tmp/mond.log" command achieve this? (4 Replies)
Hello,
I am working on a script to measure the read performance of a busybox environment. The logical choice is to use a command line like:
(time cp * /dev/null) 2> /tmp/howlong.txt
Ah, the rub is cp or /dev/null will only accept a single file at a time.
The result in the txt file is and... (1 Reply)
I stumbled across a somewhat strange behavior of tar and find no explanation for it: i was testing a DVD for read errors and thought to simply tar the content and direct the output to /dev/null:
tar -cvf - /my/mountpoint/*ts > /dev/null
This way i expected the system to read the complete... (4 Replies)
How are these two different? They both prevent output and error from being displayed. I don't see the use of the "&"
echo "hello" > /dev/null 2>&1
echo "hello" > /dev/null 2>1 (3 Replies)
Hi Guru's,
I am trying to test the network speed or load by this command.

I apologize if this question has been answered else where or is too elementary.
I ran across a KSH script (long unimportant story) that does this:
if ; then
CAS_SRC_LOG="/var/log/cas_src.log 2>&1"
else
CAS_SRC_LOG="/dev/null 2>&1"
fithen does this:

I'm using an text-to-speech synthesis in a script, and I need to redirect it's output to /dev/null

glgetshaderinfolog
GLGETSHADERINFOLOG(3G) OpenGL 3.3 GLGETSHADERINFOLOG(3G)NAME
glGetShaderInfoLog - Returns the information log for a shader object
C SPECIFICATION
void glGetShaderInfoLog(GLuint shader, GLsizei maxLength, GLsizei *length, GLchar *infoLog);
PARAMETERS
shader
Specifies the shader object whose information log is to be queried.
maxLength
Specifies the size of the character buffer for storing the returned information log.
length
Returns the length of the string returned in infoLog (excluding the null terminator).
infoLog
Specifies an array of characters that is used to return the information log.
DESCRIPTION
glGetShaderInfoLog returns the information log for the specified shader object. The information log for a shader object is modified when
the shader is compiled. The string that is returned will be null terminated.
glGetShaderInfoLog returns in infoLog as much of the information log as it can, up to a maximum of maxLength characters. The number of
characters actually returned, excluding the null termination character, is specified by length. If the length of the returned string is not
required, a value of NULL can be passed in the length argument. The size of the buffer required to store the returned information log can
be obtained by calling glGetShader() with the value GL_INFO_LOG_LENGTH.
The information log for a shader object is a string that may contain diagnostic messages, warning messages, and other information about the
last compile operation. When a shader object is created, its information log will be a string of length 0.
NOTES
The information log for a shader object is the OpenGL implementer's primary mechanism for conveying information about the compilation
process. Therefore, the information log can be helpful to application developers during the development process, even when compilation is
successful. Application developers should not expect different OpenGL implementations to produce identical information logs.
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 maxLength is less than 0.
ASSOCIATED GETS
glGetShader() with argument GL_INFO_LOG_LENGTH
glIsShader()
