Bash – Fix Syntax Error Near Unexpected Token ‘(‘

You're nesting single quotes within single quotes. That doesn't work.

Try using "double quotes" in the inner expression.

So what in the world is wrong with my code?

To check your shell scripts you can use ShellCheck. Here is the output from checking your code:

1. You are missing a few fis.

   Adding the fis generates a new error:

   

2. drivetest() appears to be missing a closing }

   Correcting this leaves you with a few warnings (which I will leave for you to fix):

   

Corrected code:

#!/bin/bash

drivetest()
{
        echo "How much data do you want to write (in MiB):"
        read data
        echo "Are you sure you want to perform a $data MiB write onto your disk?[Y/N]"
        read confirm
        if [ "$confirm" == "Y" ]; then
                dd bs=1M count=$data if=/dev/zero of=test conv=fdatasync
        elif [ "$verify" == "y" ]; then
                dd bs=1M count=$data if=/dev/zero of=test conv=fdatasync
        else
                echo "Exiting the test."
        fi
}


stresstest()
{
        echo "How long is your stress(tips: Use letters along numbers like s,m,h. If you type number with OUT letter, default as second):"
        read time
        echo "How many CPU workers do you want?"
        read cpu_worker
        sudo stress --cpu $cpu_worker --timeout $time
        echo ""
        echo -e "${yellow}Thermal results:${res}"
        sensors
}

        echo "Type 1 for a drive test.    "
        echo "Type 2 for a stress test.   "
        echo "Type 3 to perform all tests."
        echo "Type other stuffs to exit.  "
        read value

ShellCheck - A shell script static analysis tool

ShellCheck is a GPLv3 tool that gives warnings and suggestions for bash/sh shell scripts:

Screenshot of a terminal showing problematic shell script lines highlighted.

The goals of ShellCheck are

• To point out and clarify typical beginner's syntax issues that cause a shell to give cryptic error messages.

• To point out and clarify typical intermediate level semantic problems that cause a shell to behave strangely and counter-intuitively.

• To point out subtle caveats, corner cases and pitfalls that may cause an advanced user's otherwise working script to fail under future circumstances.
