Unexpected end of file Bash(last line)

Question

I tried almost all solutions suggested here but this very simple code of mine keeps showing this error

x=1
echo $x
while [$x -le 5];
do
echo $x
x=$(($x+1))
done

:

-sh-4.1$ sh test1.sh
1
test1.sh: line 10: syntax error: unexpected end of file

line 10 is one line after the "done" command. I know it has something to do with the spaces, but there aren't any spaces in my program.

I used the spaces. I feel it should work but i stil get the same error — RAJKUMAR PADILAM, Dec 22 '14 at 00:38
Do you have DOS line endings in your script? try `cat -v test1.sh` and see if you're having ugly `^M` at the end of your lines. — gniourf_gniourf, Dec 22 '14 at 00:41

You must have spaces around [ ] to do the whole script working, so :

x=1
echo $x
while [ $x -le 5 ]; do
#      ^        ^
#    space    space
    echo $x
    x=$(($x+1))
done

or with bash arithmetic :

x=1
echo $x
while ((x < 5)); do
    echo $((x++))
done

Thanks. I just did the same thing. I copied and pasted the exact first snippet of yours, but it is still giving the same error. – RAJKUMAR PADILAM Dec 22 '14 at 00:28
Can I try anything else. I just can't get rid of this error. – RAJKUMAR PADILAM Dec 22 '14 at 00:39
Are you sure you are running bash and not another shell ? `echo $SHELL` will tell you – Gilles Quénot Dec 22 '14 at 00:52
yes, when I do $SHELL, it gives me /bin/sh – RAJKUMAR PADILAM Dec 22 '14 at 15:44

@RAJKUMARPADILAM, `/bin/sh` is not bash. – Charles Duffy Nov 04 '15 at 17:27

try put a header into the script

#!/bin/bash

this way linux will automatically interpret the script as a bash script.

I am using the header. ##!/bin/bash -vx – RAJKUMAR PADILAM Dec 22 '14 at 15:45

@RAJKUMARPADILAM, `##!/bin/bash` is not `#!/bin/bash`. – Charles Duffy Nov 04 '15 at 17:28

I found the problem - carriage-return characters in the file.

I was typing the script in Windows (text pad) and executing it on Linux. The editor on Windows ends lines with \r\n; when running the script on Linux, the presence of \r was creating a problem.

Using vi as editor helped me resolve this issue.
