Question

I am facing a problem in a bash shell script. This script is supposed to execute another shell script (./script here) and the output of the script is redirected to a file(tmp). Then the file should be read line by line and for each of the lines the same script(./script) should be executed giving the line as argument and the result should be stored in a file(tmp1). Eventually these results should be appended to the first file(tmp).

I am pasting my script below:

./script $1 $2 > tmp
cat tmp | while read a
do
 ./script $a $2 >> tmp1
done

cat tmp1 | while read line
do
 ./script $line $2 >> tmp
done

I get the following error when I execute the script “./script: line 11: syntax error: unexpected end of file”

Can anyone please help me out in this??

Thanks a lot in advance.

The script file has DOS/Windows line endings. Try this command, then run your script:

dos2unix ./script

You’re probably editing the file using a Windows editor and that’s adding \r (0x0d) to the end of each line. This can be removed by using dos2unix.
