Bash script shows error for "pwd", simple script

Question

I'm trying to make a Bash shell script but it is not working. Here is the contents of the script:

#!/bin/bash pwd 

I would expect this to print out the current directory. Instaed, it prints this:

: not found: build.sh: #!/bin/bash : not found: build.sh: : not found: build.sh: pwd 

Why is it doing that? I can't find any articles of other people having this problem.

I did chmod 777 on the script, and am running it like so:

sh build.sh 

Answer 1

The file probably has DOS/Windows-style line endings.

See "Are shell scripts sensitive to encoding and line endings?" on stackoverflow.

BTW, you should almost never use chmod 777 (do you really want all users to be able to edit the script?), and run scripts with ./build.sh rather than explicitly using sh.
