Welcome on the FAQ!

How do I restart a failed script?

To restart a script previously failed, you just have to rerun it.
It will restart from the last failed step.
To force the restart from the first stop, you can use --fromscratch parameter from command line, or restart from a specific step using --fromstep parameter

My script is launched by a scheduler (or crontab), how can I know if it's running or not?

You can use the --status parameter from command line.
Quotation:

./example1.sh --status
example1 status [STOPPED]

Quotation:

./example5.sh --status
example5 status [RUNNING]

How do I kill a running script?

To kill a script you can use the --kill parameter from command line
Quotation:

./example5.sh --kill
[2017/12/20 09:30:28] Killing PID 10140

Why do the script exit with an error?

If a command launched in the script exit with an exit status different than 0 ($?), DjeShellSteps will end with this error code.
To avoid this, you can change use the "true" command using || true
Replace:
Quotation:

ls /tmsd

By:
Quotation:

ls /tmsd || true

By this way, the script will continue without any error.

How can I display a specific help message from command line?

To add a specific help message from command line, you just have to fill the Help variable inside you rscript.

Example:

Help="<input>;Input file name|<output>;Output file name"

Will display a specific help when using --help parameter

$./my_script.sh --help

./my_script.sh                                (powered by DjeShellSteps v1.01)

                                              (c) Jerome DESMOULINS
