"command not found" when running shell script

Question

Here is the simple script.sh file I have:

#!/bin/bash
pwd
date
ls -lg

I have used chmod +x to make the file executable, but when running it with ./script.sh I get command not found: pwd command not found: date and only the ls -lg command works. I'm a bit perplexed as to why the first two commands aren't working because when I type them into the command terminal they work the way they should.

Welcome to stackoverflow! Can you edit the post and copy-paste complete and exact error messages? (Just everything from your terminal including yourprompt$ ./script.sh until the script exits.) This is very helpful in file and character encoding issues, because even a missing or additional space, period or colon can hint at what's wrong and where. — that other guy

Try cat -A script.sh. This will show you any hidden characters. If cat -A doesn't work, try cat -v. — Keith Thompson

Maybe your (non-interactive) bash path is all messed up. Try adding some echo's in there, like echo $PATH — Xen2050

Also do not use a variable called PATH (cause it is already used :)

how valuable clue you gave us. I was making mistake and wasn't work my code just because I used a variable with name PATH

Maybe there is a (invisible) character there that should not be there. Try typing it again from scratch in the environment that it will run (ex: Linux) or use this command od -c /folder/script.sh to reveal those pesky characters.

Thanks, there did in fact appear to be an invisible character somewhere. I retyped the file from scratch and suddenly it worked just fine.
