Hello! I get this error when running the script

RaspiBackup.sh: 122: RaspiBackup.sh: Syntax error: Bad for loop variable

dolorosus commented 4 years ago

ok this looks strange, so I need some more information.

Please post the output of:

uname -a bash --version ls -lisa /bin/bash

Here you have it:

Stunning...

Software env looks good.

So the script seemed to be called by sh instead of bash. The shebang points to /bin/bash, but if you insist on running it with the shell (e.g. calling it with "sh RaspiBackup.sh") the shebang will not force the script to be run with bash.

Call it either with "bash RaspiBackup.sh" or simply "RaspiBackup.sh" and it will work.

with bash, it goes! (without it, nope) Thanks!
