问题
The line in my shell script is
OUTPUTMESSAGE="****Warning error $MYERRORNUM ****"
echo $OUTPUTMESSAGE
The asterisks are expanded to file names so it looks like
file1 file2 file 3 file4 Warning error 404 file1 file2 file 3 file4
How do I prevent the * expansion in echo?
回答1:
Quote the variable name not only in assignment, but also in your echo command:
OUTPUTMESSAGE="****Warning error $MYERRORNUM ****"
echo "$OUTPUTMESSAGE"
