sed and single quote [']

Question

I have a file readme.txt

in which I want to find the text

'I like pizza'

and remove the ' character with sed cmd and to modify to:

I like pizza

I have tried with this script

#!/bin/bash

echo $1'/readme.txt'

$1/build.ninja
sed -i "s|\'I like pizza\'|I like pizza|g" $1/readme.txt

but i does not work

What was wrong with `sed -i "s/'//g" $1/readme.txt` or `sed -i "s|'I like pizza'|I like pizza|g" $1/readme.txt`? See https://ideone.com/O4YurK — Wiktor Stribiżew, Nov 30 '21 at 22:49

To remove all single quotation marks you can use

sed -i "s/'//g" $1/readme.txt

Or, if you really simply want to replace a literal 'I like pizza' with I like pizza, you can use

sed -i "s|'I like pizza'|I like pizza|g" $1/readme.txt

#!/bin/bash
s="'I like pizza'"
sed "s|'I like pizza'|I like pizza|g" <<< "$s"
sed "s|'||g" <<< "$s"

Output:

I like pizza
