| . | Matches single character. |
| * | Wild character Example C* if found would pull up CC or CAT… |
| {} | Matches any character contained within the bracket. |
| ^ | Represents the beginning of the line, so if you did ^T it would search for any sentence starting with a T. |
| $ | Represents the end of the line, so if you did $. then it would pull up any lines that ended with . |
| \ | Means to take the next character serious so you could search for C\ C. |
Note: Be careful using the characters $, *, [, ^, |, (, ), and \ in the pattern list because they are also meaningful to the shell. It is safest to enclose the entire pattern list in single quotes ‘… ‘.
