In the following script I get an error:
syntax error: unexpected end of file
What is this error how can I resove it? It is pointing at the line whee the function is called.

If you do a grep (-A1: + 1 line context)
grep -A1 "if " cldtest.sh
you find some embedded ifs, and 4 if/then blocks.
grep "fi " cldtest.sh
only reveals 3 matching fi statements. So you forgot one fi too.
I agree with camh, that correct indentation from the beginning helps to avoid such errors. Finding the desired way later means double work in such spaghetti code.
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.
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 > file2
I have encountered the same error while trying to execute a script file created in windows OS using textpad. so that one can select proper file format like unix/mac etc.. or recreate the script in linux iteself.
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 << 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 << EOSQL
SET @@SESSION.SQL_LOG_BIN=0;
CREATE USER 'root'@'%';
EOSQL
fi
Unrelated to the OP's problem, but my issue was that I'm a noob shell scripter. All the other languages I've used require parentheses to invoke methods, whereas shell doesn't seem to like that.
function do_something() {
# do stuff here
}
# bad
do_something()
# works
do_something
I had this problem when running some script in cygwin. Fixed by running dos2unix
on the script, with proper description of problem and solution given in that answer
In my case, I found that placing a here document (like sqplus ... << 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...
in my case the issue was in the EOL Conversion. (End Of Line).
i created the file on windows and only after i converted the EOL from windows(CR LF) to unix(LF), everything went well.
I did the conversion with Notepad++ very easily from: Edit -> EOL Conversion -> Unix(LF)
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
