[SOLVED] Check if string exists in list in one line?

Issue

Trying to do git diff --name-only hash1 hash2, and it gives something like:

package.json
index.ts

...listing the files.

How do I create a one-liner bash command to then check if it includes package.json?

git diff --name-only hash1 hash2 | includes package.json

Solution

Use grep like this:

grep -Fxq package.json

• -F turns off regular expression matching so package.json doesn't match packageXjson, packageYjson, etc.
• -x turns off substring matching so package.json doesn't match Xpackage.json, package.jsonY, etc.
• and -q suppresses normal output so you get only whether there is a match or not.
