Make sure the name of the directory in which the  sh file is present does not have a space character  e g  Say if it is in a folder called  New Folder   you re bound to come across the error that you ve cited  Instead just name it as  New Folder   I hope this helps

I got this answer from this similar problem on StackOverflow  Open the file in Vim and try   set fileformat unix     Convert eh line endings to unix endings and see if that solves the   issue  If editing in Vim  enter the command  set fileformat unix and   save the file  Several other editors have the ability to convert line   endings  such as Notepad   or Atom   Thanks  lemongrassnginger

Missing a closing brace on a function definition will cause this error as I just discovered  function whoIsAnIidiot         echo  quot you are for forgetting the closing brace just below this line   quot   Which of course should be like this    function whoIsAnIidiot         echo  quot not you for sure quot

i also just got this error message by using the wrong syntax in an if clause   else if  syntax error  unexpected end of file   elif  correct syntax    i debugged it by commenting bits out until it worked

I think file sh is with CRLF line terminators   run  dos2unix file sh   then the problem will be fixed   You can install dos2unix in ubuntu with this   sudo apt-get install dos2unix

Another thing to check  just occured to me     terminate bodies of single-line functions with semicolon   I e  this innocent-looking snippet will cause the same error   die      test -n       amp  amp  echo       exit 1     To make the dumb parser happy   die      test -n       amp  amp  echo       exit 1

So I found this post and the answers did not help me but i was able to figure out why it gave me the error  I had a  cat  gt  temp txt  lt  EOF some content EOF   The issue was that i copied the above code to be in a function and inadvertently tabbed the code  Need to make sure the last EOF is not tabbed

I was able to cut and paste your code into a file and it ran correctly   If you execute it like this it should work   Your  file sh       bin bash   june 2011  if      -lt 3 -o    -gt 3    then    echo  Error    Usage   0 host database username     exit 0 fi   The command       file sh arg1 arg2 arg3   Note that  file sh  must be executable     chmod  x file sh   You may be getting that error b c of how you re doing input  w  a pipe  carrot  etc     You could also try splitting the condition into two   if      -lt 3           -gt 3    then    echo  Error    Usage   0 host database username     exit 0 fi   Or  since you re using bash  you could use built-in syntax   if       -lt 3       -gt 3     then    echo  Error    Usage   0 host database username     exit 0 fi   And  finally  you could of course just check if 3 arguments were given  clean  maintains POSIX shell compatibility    if      -ne 3    then    echo  Error    Usage   0 host database username     exit 0 fi

Apparently  some versions of the shell can also emit this message when the final line of your script lacks a newline

User · Answer

I just cut-and-pasted your example into a file  it ran fine under bash   I don t see any problems with it   For good measure you may want to ensure it ends with a newline  though bash shouldn t care    It runs for me both with and without the final newline    You ll sometimes see strange errors if you ve accidentally embedded a control character in the file   Since it s a short script  try creating a new script by pasting it from your question here on StackOverflow  or by simply re-typing it   What version of bash are you using    bash --version   Good luck
