在 shell 脚本中执行 mailx 命令

Question

I have a simple shell script that executes a.sql script. When the.sql script has completed, the shell script sends an email to a specified address notifying whether or not the.sql script ran successfully.

My problem is that the subject line is being truncated. I am using a simple IF statement to determine the subject line:

grep 'ORA-' $OUTFILE > /dev/null 2>&1
if [ $? = 1 ]; then
    ERRORS=n
    SUBJECT= "$VERSION script successful"
else
    ERRORS=y
    SUBJECT="$VERSION script had error(s)"
fi

This works fine. However, when I execute the mailx command, the subject line is truncated to "Development" or "Production" depending on the version of the script that has been executed:

mailx -s $SUBJECT $EMAIL < $MAILFILE

I know the subject line needs to be in double quotes if it includes embedded spaces, but this does not seem to work correctly when assigned to a variable.

Is there a way around this? Is there a way to escape the double quotes

Answer 1

You need to quote $SUBJECT as you use it, ie

mailx -s "$SUBJECT" $EMAIL < $MAILFILE

Also there should be no space in

SUBJECT="$VERSION script successful"
