Cron job help

[Victor87]

Hello all

I try to add an cron job on truenas scale to grab automatic the epg with webgrabplus app installed from truechart.

If I run the command "/defaults/update.sh" in the pod shell of the webgrab app, everything works perfect. It will look like this: "root@webgrabplus-696c8d9dc8-8f7ls:/# /defaults/update.sh".

But on the cron job all the path what I was trying to add it always fail with error "no such file or directory".

How can I find the correct path of the file?

Thanks

1. Make sure the file has execute permission

Code:

chmod a+x {filename}

2. Prefix the CRON task with

Code:

/bin/sh {path/filename}

I'm beginner and I don't understand very well all the stuff
If I run "chmod a+x update.sh" or "chmod a+x defaults/update.sh"on shell it says no such file or directory.
On shell pod it looks like in the picture.

Also on cron job with comand "/bin/sh default/update.sh" it doesn't find the path or directory

Don't use relative paths. Use absolute paths.

You are missing the leading "/" <--- absolute path

I test with and without. You mean /defaults/update.sh? Doesn't work

I am guessing you don't have the shell shebang in the header of the file.

Code:

#!/bin/sh

Code:

#!/bin/sh

Means that the command in Cron job must look like this?
#!/bin/sh /defaults/update.sh

Or you mean on the wg3-cron file from webgrabplus app? Picture attached
