Fish: The file is not executable by this user

Question

I made fish function in ~/.config/fish/functions/confgit.fish:

function confgit
    /home/john/Projects/confgit $argv
end

But when I run this function it just says:

fish: The file “/home/john/Projects/./confgit” is not executable by this user  
    /home/john/Projects/./confgit $argv  
    ^  
in function 'confgit'

The config file is normal python script. If I run it by ./confgit it runs fine.

There are the permissions of the script:

-rwxr-xr-x  1 john john 5.8K 29. nov 02.04 confgit*

How can I fix this so I can use this function ?
Thank you for help

Answer 1

I worked to reproduce your problem, and the closest thing I could emulate was this:

# file: ~/bin/janstest
echo $argv

# file: ~/bin/janstest2
function janstest
  ~/bin/janstest $argv
end

janstest It works!

and file permissions as:

stew@stewbian ~> ls -l ~/bin/jans*
-rwxr-xr-x /home/stew/bin/janstest*
-rwxr-xr-x /home/stew/bin/janstest2*

When I run it I get a similar error:

stew@stewbian ~> ~/bin/janstest2
Failed to execute process '/home/stew/bin/janstest2'. Reason:
exec: Exec format error
The file '/home/stew/bin/janstest2' is marked as an executable but could not be run by the operating system.
stew@stewbian ~ [125]>

The solution was to prepend #!/usr/bin/fish to the the script.

stew@stewbian ~> cat ~/bin/janstest2
#!/usr/bin/fish
function janstest
  ~/bin/janstest $argv
end

janstest It works
stew@stewbian ~> ~/bin/janstest2
It works
