If you post code, logs, data etc. use code-tags for better readability please.
Ok, processing the relevant part of your output:
Setting | as field separator
$NF is the last field, checking if it contains the pattern Alive
If so, the stuff in the curly braces is being done, ie. it increases the record counter r by +1 and the Alive counter a by 1. With the record counter we track how many rows we processed over all.
If it doesn't find the pattern "Alive" in the last field, it will use this line and check $NF for the pattern "Down". It increases the record counter by 1 and the Down counter d. The Down counter is not necessary but maybe for future use.
In the end, when all lines are processed, it checkes the variables and if the Alive counter is not equal the number of processed relevant rows/records, it will spit an error message as you can see.
All other lines that don't fit to the 2 rules $NF ~ /Alive/ or $NF ~ /Down/ are just bypassed.

On AIX 5.2, I use "ps -ef " command to display the process status, the field of command looks like: , the detailed contents are:

Hi,
I am writing a shell script to invoke a C++ program. Before I start the C++ program (oi7loadbalancer), I am checking if the process is already running. I start the process only if it is not already running. I have the following check in my script.

Hi all,
How can a process be aware of the signals it handles. I looked at available signal API, but couldn't find any help.
If a process defines it own handler for a signal, the default handler for that signal becomes overridden.

hello everybody!!
i want to post a question!
is there any way to get process status using C commands?
To be more specific, i want to know whether a process is running or is stop or killed.
thanks in advance! (3 Replies)
All,

Hi,
I want to write one program in C in Unix OS which will check the running status of a process time to time. If the process is stopped somehow by any means, it will ensure that the process is restarted and only one copy of the process image should run in memory at any point of time for the user....

GLGETACTIVEATOMICCOU(3G) OpenGL Manual GLGETACTIVEATOMICCOU(3G)NAME
glGetActiveAtomicCounterBufferiv - retrieve information about the set of active atomic counter buffers for a program
C SPECIFICATION
void glGetActiveAtomicCounterBufferiv(Gluint program, GLuint bufferIndex, GLenum pname, GLint *params);
PARAMETERS
program
The name of a program object from which to retrieve information.
bufferIndex
Specifies index of an active atomic counter buffer.
pname
Specifies which parameter of the atomic counter buffer to retrieve.
params
Specifies the address of a variable into which to write the retrieved information.
DESCRIPTION
glGetActiveAtomicCounterBufferiv retrieves information about the set of active atomic counter buffers for a program object. program is the
name of a program object for which the command glLinkProgram() has been issued in the past. It is not necessary for program to have been
linked successfully. The link may have failed because the number of active atomic counters exceeded the limits.
bufferIndex specifies the index of an active atomic counter buffer and must be in the range zero to the value of
GL_ACTIVE_ATOMIC_COUNTER_BUFFERS minus one. The value of GL_ACTIVE_ATOMIC_COUNTER_BUFFERS for program indicates the number of active atomic
counter buffer and can be queried with glGetProgram().
If no error occurs, the parameter(s) specified by pname are returned in params. If an error is generated, the contents of params are not
modified.
If pname is GL_ATOMIC_COUNTER_BUFFER_BINDING, then the index of the counter buffer binding point associated with the active atomic counter
buffer bufferIndex for program is returned.
If pname is GL_ATOMIC_COUNTER_BUFFER_DATA_SIZE, then the implementation-dependent minimum total buffer object size, in baseic machine
units, required to hold all active atomic counters in the atomic counter binding point identified by bufferIndex is returned.
If pname is GL_ATOMIC_COUNTER_BUFFER_ACTIVE_ATOMIC_COUNTERS, then the number of active atomic counters for the atomic counter buffer
identified by bufferIndex is returned.
If pname is GL_ATOMIC_COUNTER_BUFFER_ACTIVE_ATOMIC_COUNTER_INDICES, then a list of the active atomic counter indices for the atomic counter
buffer identified by bufferIndex is returned. The number of elements that will be written into params is the value of
GL_ATOMIC_COUNTER_BUFFER_ACTIVE_ATOMIC_COUNTERS for bufferIndex.
If pname is GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_VERTEX_SHADER, GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_TESS_CONTROL_SHADER,
GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_TESS_EVALUATION_SHADER, GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_GEOMETRY_SHADER,
GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_FRAGMENT_SHADER, GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_COMPUTE_SHADER then a boolean value
indicating whether the atomic counter buffer identified by bufferIndex is referenced by the vertex, tessellation control, tessellation
evaluation, geometry, fragment or compute processing stages of program, respectively, is returned.
NOTES
glGetActiveAtomicCounterBufferiv is available only if the GL version is 4.2 or higher.
GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_COMPUTE_SHADER is available only of the GL version is 4.3 or higher.
ERRORS
GL_INVALID_VALUE is generated if program is not the name of a program object for which glLinkProgram() has been called in the past.
GL_INVALID_VALUE is generated if bufferIndex is greater than or equal to the value of GL_ACTIVE_ATOMIC_COUNTER_BUFFERS for program.
GL_INVALID_ENUM is generated if pname is not one of the accepted tokens.
