Alternatively, you can find all the teams ending with United using the following syntax:. If you don't want to return the actual lines that match a pattern using grep but you just want to know how many there are you can use the following syntax:. If the pattern was matched twice then the number 2 would be returned. Imagine you have a list of place names with the countries listed as follows:. You may have noticed that colwyn bay has no country associated with it. To search for all the places with a country you could use the following syntax:.
The results returns would be all the places except for colwyn bay. This obviously only works for places that end in land hardly scientific. You can invert the selection using the following syntax:. This would find all the places that didn't end with land. Imagine you have an input file which is used by a third party application which stops reading the file when it finds an empty line as follows:.
When the application gets to the line after liverpool it will stop reading meaning colwyn bay is missed entirely. You can use grep to search for blank lines with the following syntax:. This isn't particularly useful because it just returns the blank lines. You could, of course, get a count of the number of blank lines as a check to see if the file is valid as follows:. It would, however, be more useful to know the line numbers that have a blank line so that you can replace them.
You can do that with the following command:. Using grep you can determine which lines in a file have uppercase characters using the following syntax:. The square brackets  let you determine the range of characters. In the above example, it matches any character which is between A and Z. Therefore to match lowercase characters, you can use the following syntax:. If you want to match only letters and not numerics or other symbols you can use the following syntax:.
You can do the same with numbers as follows:. Imagine you have a file with phone numbers as follows:. You know the first part of the number needs to be three digits and you want to find the lines that do not match this pattern. From the previous example, you know that  returns all numbers in a file.
In this instance, we want the lines that start with three numbers followed by a hyphen -. You can do that with the following syntax:. The  will search for any number between 0 and 9. As this is included three times it matches 3 numbers. Finally, there is a hyphen to denote that a hyphen must succeed the three numbers. By using the curly brackets you can make the search smaller as follows:. The curly brackets can also be used as follows:. Thus far we have looked at pattern matching within individual files but grep can use the output from other commands as the input for pattern matching.
A great example of this is using the ps command which lists active processes. For example, run the following command:. All of the running processes on your system will be displayed. You can use grep to search for a particular running process as follows:. The grep command is a fundamental Linux command and it is one that is well worth learning as it will make your life much easier when searching for files and processes when using the terminal.
