Which of the following commands can be used to view a file and do search operations within it while viewing the contents?

`less` is an interactive terminal pager that displays file contents one screen at a time and supports search operations using `/` for forward search and `?` for backward search while viewing the file. Unlike editors, it opens files read-only, and unlike `more`, it allows bidirectional navigation through the content.

`find` is used to locate files and directories within a filesystem based on criteria such as name or type, not to view or search within file contents.

`grep` searches for patterns within files and prints matching lines to stdout, but it does not provide an interactive viewing interface for browsing the full file.

`report` is not a standard Linux/Unix command for viewing files.

`see` is not a standard Linux/Unix command for viewing or searching file contents.
