fish shell : exec format error












0














On an Ubuntu ($ uname -a : Linux kumanaku 4.15.0-43-generic #46-Ubuntu SMP Thu Dec 6 14:45:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux), I just installed fish ($ fish --version : fish, version 2.7.1) using the following commands :



sudo apt-add-repository ppa:fish-shell/release-2

sudo apt-get update

sudo apt-get install fish

chsh -s /usr/bin/fish

echo /usr/bin/fish | sudo tee -a /etc/shells


I can launch fish and use it but when I launch a simple shell file like :



echo "something"


I got the following message :



$ ./myscript.sh



Failed to execute process './myscript.sh'. Reason:

exec: Exec format error

The file './myscript.sh' is marked as an executable but could not be run by the operating system.


There's no shebang in my script. If I add #!/usr/bin/env fish, everything's ok (i.e. the script is successfully launched) but I'd like to avoid such a line to keep my script compatible with different shells.



Any idea to help me ?
