Symlink available commands to bin

[ob7]

This is another question.

Many times we run commands or write scripts that access common paths in linux, such as /bin/bash.

How can I make nixos automatically symlink all commands to the bin directory?

[matthewbauer]

The "Nix" way to do this is to avoid these paths.#!/usr/bin/env $bin should work in all cases.

You definitely can set up a symlink from /bin to /run/current-system/sw/bin but you could also just use the current-system path. Either way though there's probably a better way that doesn't involve hard coding a path.

So my scrips should say:
#!/user/bin/env $bin/bash instead ???
or just #!/usr/bin/env $bin
no matter if its bash or php or perl or python etc?

[Mic92]

No, @matthewbauer meant you should place the interpreter inplace of $bin: ex.: #!/usr/bin/env bash, #!/usr/bin/env php or #!/usr/bin/env python

Thank you

how about #!/usr/bin/env awk -f ???

[Mic92]

$ cat ./foo.awk
#!/usr/bin/env -S awk -f
END { printf "WORKS" }
$ ./foo.awk </dev/null
WORKS

Thanks. -S now works after updating my coreutils to 8.30. https://stackoverflow.com/questions/1418245/invoking-a-script-which-has-an-awk-shebang-with-parameters-vars
