如何grep带有撇号的文本文件？

Question

people... Im coding a linux bash file and I need it to grep for the text 'Josh''1234 . Is there any way to ignore those apostrophes? heres what I tried: (Josh is set as usr and 1234 as pas .)

if grep -q '\'$usr\'\'$pas\''; then
    echo username and password correct
else
    echo INCORECT
    sleep 10
fi

Just quote with double quotes, so that single quotes can be included normally:

grep "'$usr''$pas"
#    ^           ^
#     ^    ^^
#     single quotes to match
