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 :
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 ?
