Question

I want my shell can only find out the pattern in the quote,
but the result also returned something like "MSGxxxxx"
Anybody who can give me some advise?

Here is my script:

if egrep -e 'Msg|duplicate|deadlock|status = -|terminated due to disconnect' MYFILE.log
 then
    echo "I found something in your RAW data."    
  else
    echo "Nothing found!"
fi

Answer 1

Use the -w flag in order to select only those lines containing matches that form whole words.

if egrep -w -e 'Msg|duplicate|deadlock|status = -|terminated due to disconnect' file
then
    echo "I found something in your RAW data."    
else
    echo "Nothing found!"
fi

Alternatively, use a word boundary \b as shown below:

if egrep -e '\bMsg\b|duplicate|deadlock|status = -|terminated due to disconnect' file
then
    echo "I found something in your RAW data."    
else
    echo "Nothing found!"
fi
