make sense and corrected the script(though earlier it was running fine (), don't know how).
Currently I'm trying to get the command I'm running using below sample test script:
Code:
$ [] cat bgPIDTest.ksh
# Some function that takes a long time to process
longprocess() {
# Sleep up to 14 seconds
#sleep $((RANDOM % 15))
sleepTime=$((RANDOM % 5))
# Randomly exit with 0 or 1
exitCode=$((RANDOM % 2))
echo "sleeping for: $sleepTime with exit code: $exitCode "
sleep $sleepTime
exit $exitCode
}
pids=""
failCnt=0
# Run five concurrent processes
( longprocess ) &
# store PID of process
pids+=" $!"
echo PID $pids
( longprocess ) &
# store PID of process
pids+=" $!"
echo PID $pids
( longprocess ) &
# store PID of process
pids+=" $!"
echo PID $pids
( longprocess ) &
# store PID of process
pids+=" $!"
echo PID $pids
( longprocess ) &
# store PID of process
pids+=" $!"
echo PID $pids
( longprocess ) &
# store PID of process
pids+=" $!"
echo PID $pids
# Wait for all processes to finish, will take max 14s
echo "initial failCnt is $failCnt"
for p in $pids; do
#if wait $p; then
if ! wait $p; then
cmdJobNM=`ps -p $p -o command=`
failCnt=`expr $failCnt + 1`
echo "failed command is --> $cmdJobNM, PID: $p"
fi
done
echo "total failCnt is $failCnt"
if [ $failCnt -gt 0 ]; then
exit -1
fi
Output:
Code:
$ [] ksh bgPIDTest.ksh
PID 15858
sleeping for: 2 with exit code: 1
PID 15858 15859
sleeping for: 4 with exit code: 0
PID 15858 15859 15860
sleeping for: 0 with exit code: 0
PID 15858 15859 15860 15861
sleeping for: 3 with exit code: 0
PID 15858 15859 15860 15861 15862
sleeping for: 3 with exit code: 1
PID 15858 15859 15860 15861 15862 15863
initial failCnt is 0
sleeping for: 1 with exit code: 0
failed command is --> , PID: 15858
failed command is --> , PID: 15862
total failCnt is 2
Still I'm not getting the command, so that I can awk'ed the passed argument and put into a file. So the logic will be:
Once I'll restart script:
if this new file exist
take this new file
else
use old config file
once successfully done, I'll remove the error file (if any). Please suggest if this feasible.

dpid.h
dpid.h(3) libdaemon dpid.h(3)NAME
dpid.h -
Contains an API for manipulating PID files.
SYNOPSIS
#include <sys/types.h>
Defines
#define DAEMON_PID_FILE_KILL_WAIT_AVAILABLE 1
This variable is defined to 1 iff daemon_pid_file_kill_wait() is supported.
Typedefs
typedef const char *(* daemon_pid_file_proc_t )(void)
Prototype of a function for generating the name of a PID file.
Functions
const char * daemon_pid_file_proc_default (void)
A function for creating a pid file name from daemon_pid_file_ident.
int daemon_pid_file_create (void)
Creates PID pid file for the current process.
int daemon_pid_file_remove (void)
Removes the PID file of the current process.
pid_t daemon_pid_file_is_running (void)
Returns the PID file of a running daemon, if available.
int daemon_pid_file_kill (int s)
Kills a running daemon, if available.
int daemon_pid_file_kill_wait (int s, int m)
Similar to daemon_pid_file_kill() but waits until the process died.
Variables
const char * daemon_pid_file_ident
Identification string for the PID file name, only used when daemon_pid_file_proc is set to daemon_pid_file_proc_default().
daemon_pid_file_proc_t daemon_pid_file_proc
A function pointer which is used to generate the name of the PID file to manipulate.
Detailed Description
Contains an API for manipulating PID files.
Definition in file dpid.h.
Define Documentation
#define DAEMON_PID_FILE_KILL_WAIT_AVAILABLE 1
This variable is defined to 1 iff daemon_pid_file_kill_wait() is supported. Since:
0.3
See also:
daemon_pid_file_kill_wait()
Definition at line 82 of file dpid.h.
Typedef Documentation
typedef const char*(* daemon_pid_file_proc_t)(void)
Prototype of a function for generating the name of a PID file.
Definition at line 37 of file dpid.h.
Function Documentation
int daemon_pid_file_create (void)
Creates PID pid file for the current process. Returns:
zero on success, nonzero on failure
Examples:
testd.c.
pid_t daemon_pid_file_is_running (void)
Returns the PID file of a running daemon, if available. Returns:
The PID or negative on failure
Examples:
testd.c.
int daemon_pid_file_kill (int s)
Kills a running daemon, if available. Parameters:
s The signal to send
Returns:
zero on success, nonzero on failure
int daemon_pid_file_kill_wait (int s, int m)
Similar to daemon_pid_file_kill() but waits until the process died. This functions is new in libdaemon 0.3. The macro
DAEMON_PID_FILE_KILL_WAIT_AVAILABLE is defined iff libdaemon supports this function.
Parameters:
s The signal to send
m Seconds to wait at maximum
Returns:
zero on success, nonzero on failure (timeout condition is considered a failure)
Since:
0.3
See also:
DAEMON_PID_FILE_KILL_WAIT_AVAILABLE
Examples:
testd.c.
const char* daemon_pid_file_proc_default (void)
A function for creating a pid file name from daemon_pid_file_ident. Returns:
The PID file path
int daemon_pid_file_remove (void)
Removes the PID file of the current process. Returns:
zero on success, nonzero on failure
Examples:
testd.c.
Variable Documentation
const char* daemon_pid_file_ident
Identification string for the PID file name, only used when daemon_pid_file_proc is set to daemon_pid_file_proc_default(). Use
daemon_ident_from_argv0() to generate an identification string from argv[0]
Examples:
testd.c.
daemon_pid_file_proc_t daemon_pid_file_proc
A function pointer which is used to generate the name of the PID file to manipulate. Points to daemon_pid_file_proc_default() by default.
