I have a small sh script that I use to backup to a remote server. It worked on Ubuntu 16.04 for years, but now on 18.04 it fails. At first I thought it was a problem with anacron, but now I think it is a problem with the script itself or with dash. Here is what is happening:



stefan@stefan-Aspire-F5-573T:/etc/cron.daily$ sudo chmod +x rsync-doc-script 
[sudo] Mot de passe de stefan :
stefan@stefan-Aspire-F5-573T:/etc/cron.daily$ ./rsync-doc-script
/bin/sh: 0: Can't open *
stefan@stefan-Aspire-F5-573T:/etc/cron.daily$ sh rsync-doc-script
opening connection using: ssh -i /home/stefan/.ssh/id_rsa -l totem MouseHouse rsync --server -vvlogDtprze.iLsfxC . /totembackup/totemdoc (11 args)
ssh: connect to host mousehouse port 22: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(235) [sender=3.1.2]
stefan@stefan-Aspire-F5-573T:/etc/cron.daily$


The error can't open * is preventing the script from running correctly when run by run-parts. Why is this error occurring?



It is not relevant that in the last line, when the script ran, it couldn't establish connection. The server is turned off now.



Here is the script:



#!/bin/sh                                                                                     *
rsync -azvv -e "ssh -i /home/stefan/.ssh/id_rsa" /home/stefan/Documents/ totem@MouseHouse:/totembackup/totemdoc

          I'd switch from using #!/bin/sh as your shebang to #!/bin/bash since you're expecting Bash features vs. /bin/sh or /bin/dash.



          Also I can't tell for sure but it looks like you have a typo on the first line where there's a stray * over to the right.



          #!/bin/sh                                                                                     *


          ^^^ Scroll over to the right to see it.



          Example



          $ cat script.bash
          #!/bin/sh *
          echo hi


          Run directly:



          $ ./script.bash

            @dessert - I state that as a general practice, if you expect features from X, use X.

            @slm That doesn't make sense... You state in your answer "... since you're expecting Bash features ...", but the OP is clearly not using any bash features in his script. I agree with dessert that the #!/bin/bash advice is misplaced. It's the "also" part of your answer that is the actual answer ;)

          • @marcelm - as I stated to dessert above, if someone is attempting to use the features of something, better to use it directly vs. indirectly. I'm not saying that the OP was actually using any Bash features per say, just that they're writing a Bash script so call it out directly vs. sh.

          • So what does that trailing asterisk (*) do in bash?

          Exactly, this asterisk is producing a syntax error when the shebang line is used, thus preventing the script from being run. OP’s script is not using any bash features though, there’s no need to make it #!/bin/bash. A shebang line #!/bin/bash * throws an error as well.
