Linux Find modified file-find command at specified time

If you do not remember after modifying the file under Linux, we need to find the files that have been changed in the specified time, and we can use Find command to look for them.

Find/opt-iname "*"-atime 1-type F

"Find the files that/opt visited the next day."

All options always return true values, and they are always executed, unless they are placed in an expression that cannot be performed. So for clarity, it's best to put them at the beginning of an expression.
