One use might be, for example, searching a log file for errors. \r\n\r\n2. find: walk a file hierarchy. Distinguished from grep in that it is a file locator, while grep searches for patterns within files. Find and grep can be used together to do both things. \r\n\r\n3. sed: stream editor. Unix utility that parses and transforms text. Many people use s, the substitute command, which changes all occurrences of the regular expression into a new value. This seems to have been the original motivation behind sed. "}}
