## To use in a program, define the following variables:
|
|
|
|
## PROGRAM=program-name
|
|
## INSTANCE_ID=program-instance-name
|
|
## _DEBUG=true/false
|
|
## _LOGGER_SILENT=true/false
|
|
## _LOGGER_VERBOSE=true/false
|
|
## _LOGGER_ERR_ONLY=true/false
|
|
## _LOGGER_PREFIX="date"/"time"/""
|
|
## _LOGGER_WRITE_PARTIAL_LOGS=true/false
|
|
|
|
## Also, set the following trap in order to clean temporary files
|
|
## trap GenericTrapQuit TERM EXIT HUP QUIT
|
|
|
|
## Then simply source ofunctions with
|
|
## source "./ofunctions.sh"
|
|
|
|
## Why use GenericTrapQuit in order to catch exitcode ?
|
|
## Logger sets {ERROR|WARN}_ALERT variable when called with critical / error / warn loglevel
|
|
## When called from subprocesses, variable of main process cannot be set. Status needs to be get via $RUN_DIR/$PROGRAM.Logger.{error|warn}.$SCRIPT_PID.$TSTAMP

## Main asynchronous execution function
|
|
## Function can work in:
|
|
## WaitForTaskCompletion mode: monitors given pid in background, and stops them if max execution time is reached. Suitable for multiple synchronous pids to monitor and wait for
|
|
## ParallExec mode: takes list of commands to execute in parallel per batch, and stops them if max execution time is reahed.
|
|
|
|
## Example of improved wait $!
|
|
## ExecTasks $! "some_identifier" false 0 0 0 0 true 1 1800 false
|
|
## Example: monitor two sleep processes, warn if execution time is higher than 10 seconds, stop after 20 seconds
|
|
## sleep 15 &
|
|
## pid=$!
|
|
## sleep 20 &
|
|
## pid2=$!
|
|
## ExecTasks "$pid;$pid2" "some_identifier" 0 0 10 20 1 1800 true true false false 1
|
|
|
|
## Example of parallel execution of four commands, only if directories exist. Warn if execution takes more than 300 seconds. Stop if takes longer than 900 seconds. Exeute max 3 commands in parallel.
|
|
## commands="du -csh /var;du -csh /etc;du -csh /home;du -csh /usr"
|
|
## conditions="[ -d /var ];[ -d /etc ];[ -d /home];[ -d /usr]"

## ExecTasks "$commands" "some_identifier" false 0 0 300 900 true 1 1800 true false false 3 "$conditions"
