awk not working as expected

I have what I am assuming to be a very simple problem. I have used the following command in scripts many times before without issues.

display=/some/file/with/data
sed -i "s/$(more ${display} | grep 110 | gawk '{ print $3 }')/"replacestring"/g" ${display}

Never had an issue with this command.

I created a script that simplified everything that was needed and have the following code:

displayText=$(more ${display} | grep 110 | gawk '{ print $3 }')

I keep receiving

line 2: syntax error: unexpected end of file.

I am very familiar with Linux so the problem has been quite irritating as the answer has escaped me. Please assist.

Not sure why you are using more. You also have backquotes around the awk script where you should have single quotes.

displayText=$(cat ${display} | grep 110 | gawk '{ print $3 }')

You will be told that this is a useless-use-of-cat (the cat command isn't needed since grep can read a file). You can just do:

displayText=$(grep 110 ${display} | gawk '{ print $3 }')

As awk can also search, this can be simplified further into:

displayText=$(gawk '/110/ {print $3}'  ${display})
