Bash Error "Unexpected token near done"

[deKoch13]

Hi!

I wrote the following little bash script:

echo Processing...

inputDir="/home/j490h/localhome/fastq/"
output_folder="/home/j490h/localhome/fastq/textfiles/"

for input_FASTQfile in `ls ${inputDir}/*fastq*`
do
        filename_only=`basename ${input_FASTQfile}`
	echo ${filename_only}
	zcat ${filename_only} | sed -n '1~4p' > ${output_folder}/${filename_only}_ReadIDs.txt
done

output_folder2="/home/j490h/localhome/fastq/textfiles/combined_textfiles/"
trimmed="trimmed"
shuffled="shuffled"
reconstructed="reconstructed"

for file1 in `ls ${output_folder}/*txt*`
do
	for file2 in `ls ${output_folder}/*txt*` 
	do
		if [ ${trimmed} in ${file1} & ${file2} ]
		then 
			cat ${file1} ${file2} > ${output_folder2}/${file1}_${file2}_combined.txt
		elif [ ${shuffled} in ${file1} & ${file2} ]
		then
			cat ${file1} ${file2} > ${output_folder2}/${file1}_${file2}_combined.txt
		elif [ ${reconstructed} in ${file1} & ${file2} ]
		then
			cat ${file1} ${file2} > ${output_folder2}/${file1}_${file2}_combined.txt
		else
			echo Invalid input FASTQfile
	done
done

and I get the error:
"Unexpected token near done" at the last two lines.
Unfortunately, I dont know why...
I already checked cat -v file.sh, but there do not seem to be unexpected characters or something...

Do you have any idea?

Greetings!

I believe you are missing a
fi
line before the last two done lines
