Check if file exists and continue else exit in Bash


I have a script that is one script in a chain of others that sends an email.

At the start of the script I want to check if a file exists and continue only if it exists, otherwise just quit.

Here is the start of my script:

if [ ! -f /scripts/alert ];
then
    echo "File not found!" && exit 0
else
        continue
fi

However I keep getting a message saying:

line 10: continue: only meaningful in a `for', `while', or `until' loop

Any pointers?


Solution

  • Change it to this:

    {
    if [ ! -f /scripts/alert ]; then
        echo "File not found!"
        exit 0
    fi
    }
    

    A conditional isn't a loop, and there's no place you need to jump to. Execution simply continues after the conditional anyway.

    (I also removed the needless &&. Not that it should happen, but just in case the echo fails there's no reason not to exit.)
