It can also be caused by piping out of a pair of curly braces on a line.

This fails:

{ /usr/local/bin/mycommand ; outputstatus=$? } >> /var/log/mycommand.log 2>&1h
do_something
#Get NOW that saved output status for the following $? invocation
sh -c "exit $outputstatus"
do_something_more

while this is allowed:

{
   /usr/local/bin/mycommand
   outputstatus=$?
} >> /var/log/mycommand.log 2>&1h
do_something
#Get NOW that saved output status for the following $? invocation
sh -c "exit $outputstatus"
do_something_more

Helpful post  I found that my error was using else if instead of elif like so   if   -z   VARIABLE1     then       do stuff else if   -z   VARIABLE2     then       do other stuff fi   Fixed it by changing to this   if   -z   VARIABLE1     then       do stuff elif   -z   VARIABLE2     then       do other stuff fi

Indentation when using a block can cause this error and is very hard to find    if     -d  var lib mysql mysql    then     usr bin mysql --protocol socket --user root  lt  lt  EOSQL         SET   SESSION SQL LOG BIN 0          CREATE USER  root          EOSQL fi      Example above will cause an error because EOSQL is indented  Remove indentation as shown below  Posting this because it took me over an hour to figure out the error   if     -d  var lib mysql mysql    then     usr bin mysql --protocol socket --user root  lt  lt  EOSQL         SET   SESSION SQL LOG BIN 0          CREATE USER  root       EOSQL fi

I have found that this is sometimes caused by running a MS Dos version of a file   If that s the case dos2ux should fix that   dos2ux file1  gt  file2

You ve got an unclosed quote  brace  bracket  if  loop  or something   If you can t see it just by looking  I d recommend a syntax colouring editor and a neat indentation style   take a copy of the script  and delete half of it  cutting it of somewhere that ought to be valid  If the script runs  as far as it can  then the problem is in the other half  Repeat until you ve narrowed down the problem

In my case  I found that placing a here document  like sqplus      lt  lt  EOF  statements indented also raise the same error as shown below     dbuser case ksh  line 25  syntax error  unexpected end of file   So after removing the indentation for this  then it went fine   Hope it helps

Edit  Note that the original post has been edited since this answer was written and has been reformatted  You should look at the history to see the original formatting to understand the context for this answer   This error occurs often when you have mismatched structure - that is  you do not have matching double quotes  matching single quotes  have not closed a control structure such as a missing fi with an if  or a missing done with a for   The best way to spot these is to use correct indentation  which will show you where you have a broken control structure  and syntax highlighting  which will show you where quotes are not matched   In this particular case  I can see you are missing a fi  In the latter part of your code  you have 5 ifs and 4 fis  However you also have a number of other problems - your backquoted touch  tmp alert txt    command is syntactically invalid  and you need a space before the closing bracket of an if test   Clean up your code  and errors start to stand out
