Forgive me for this is a very simple script in Bash. Here's the code:

#!/bin/bash
# june 2011

if [ $# -lt 3 -o $# -gt 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

after running sh file.sh:

syntax error: unexpected end of file

I had the problem when I wrote "if - fi" statement in one line:

if [ -f ~/.git-completion.bash ]; then . ~/.git-completion.bash fi

Write multiline solved my problem:

if [ -f ~/.git-completion.bash ]; then 
    . ~/.git-completion.bash
 fi

This was happening for me when I was trying to call a function using parens, e.g.

run() {
  echo hello
}

run()

should be:

run() {
  echo hello
}

run

FOR WINDOWS:

In my case, I was working on Windows OS and I got the same error while running autoconf.

  • I simply open configure.ac file with my NOTEPAD++ IDE.

  • Then I converted the File with EOL conversion into Windows (CR LF) as follows:

    EDIT -> EOL CONVERSION -> WINDOWS (CR LF)

Missing a closing brace on a function definition will cause this error as I just discovered.

function whoIsAnIidiot() {
    echo "you are for forgetting the closing brace just below this line !"

Which of course should be like this...

function whoIsAnIidiot() {
    echo "not you for sure"
}

In my case, there is a redundant \ in the like following:

function foo() {
    python tools/run_net.py \
                           --cfg configs/Kinetics/X3D_8x8_R50.yaml \
                           NUM_GPUS 1 \
                           TRAIN.BATCH_SIZE 8 \
                           SOLVER.BASE_LR 0.0125 \
                           DATA.PATH_TO_DATA_DIR ./afs/kinetics400 \
                           DATA.PATH_PREFIX  ./afs/kinetics400  \  # Error
}

There is NOT a \ at the end of DATA.PATH_PREFIX ./afs/kinetics400

For people using MacOS:

If you received a file with Windows format and wanted to run on MacOS and seeing this error, run these commands.

brew install dos2unix
sh <file.sh>

If the the script itself is valid and there are no syntax errors, then some possible causes could be:

  • Invalid end-of-lines (for example, \r\n instead of \n)
  • Presence of the byte order mark (BOM) at the beginning of the file

Both can be fixed using vim or vi.

To fix line endings open the file in vim and from the command mode type:

:set ff=unix

To remove the BOM use:

:set nobomb

For those who don't have dos2unix installed (and don't want to install it):

Remove trailing \r character that causes this error:

sed -i 's/\r$//' filename
