Why doesn't curl from bash script work?

Question

bash

There is this script:

#!/usr/bin/env bach
curl -o /home/user/local.txt http://localhost/download/server.txt

I run it like this:
$ bash /home/user/my-script.sh
In response I get:
curl: command not found
But if I execute this command immediately from the console:

$ curl -o /home/user/local.txt http://localhost/download/server.txt

then everything is great! file uploaded!
What to do????

Answer 1

different paths in PATH
echo $PATH just run
without bash
./my-script.sh

Answer 2

#!/usr/bin/env bach

man bach
No manual entry for bach

#!/bin/bash
#!/usr/bin/env bash

Answer 3

In general, it is better to set full paths to commands in scripts.
for example

#!/usr/bin/env bach
/usr/bin/curl -o /home/user/local.txt http://localhost/download/server.txt

Or at the beginning of the script, use the PATH variable.
For example

#!/bin/sh
PATH=/path/to/bin
export PATH
....
