Which of the following commands can perform searches on file contents using regular expressions?
The command 'grep' is specifically designed to search through file contents using regular expressions. It is widely used in Unix-like operating systems to search for patterns within text files. The other commands listed, such as 'find', 'locate', 'reggrep', and 'pgrep', do not have the primary function of searching text using regular expressions. 'find' is used to search for files and directories, 'locate' searches for files by name, 'pgrep' searches for processes, and 'reggrep' is not a standard command.
