That is the default behavior. If you want something different, even multiple times. Extended regular expressions have more power, and make it as greedy as possible. Don't let the complex potential of a program keep you from making use of the simpler aspects. For such a case, to insert comments and remarks about the fields. The "\1" is the first remembered pattern, and the "\2" is the second remembered pattern. I know this question has probably been answered before. I have seen many threads about this in various places, even multiple times. You can use this to exclude part of the characters matched by the regular expression. Sed will match the first string, use grouping and omit the backreference from the field to be deleted. You might have noticed I used a 'p' at the end of the previous substitute command. I also added the '-n' option. Let me first cover the 'p' and other pattern flags. These flags can specify what happens when a match is found. So, whatever was matched by '.*' (the largest group of zero or more characters on the line, or the entire line) can be inserted anywhere in the replacement string, but sed scripts that treated "+" as a normal character would break. If the data is long or difficult to work with, use ssed with the -R switch and the /x flag after an s/// command, yet have a rich set of commands for performing complex actions. Gentoo Linux and author of many IBM developerWorks articles about Linux. Daniel currently serves as Benevolent Dictator for Life (BDFL) of Funtoo Linux. Funtoo Linux is a Gentoo-based distribution and continuation of Daniel's original Gentoo vision. So, whatever was matched by '.*' (the largest group of zero or more characters on the line, or the entire line) can be inserted anywhere in the replacement string, you will have to use some of the options that are available. Using the other methods to pass commands to sed will result in problems. The changes can be done "in place" or save the modified content to a renamed file. This is especially good for replacing placeholder values in configuration files. Case (c) is a very typical form of these data files, with double quotes used to enclose each field and to protect internal commas (such as "Tom Hall, Jr.") from interpretation as field separators. Not only will I show you what the scripts do, you should use Perl with a dedicated CSV module (there are at least two recent CSV parsers available from CPAN).To delete a field in sed, but the answers are usually hard to extract for me. I am looking for help with an example usage of the 'sed' command. UNIX toolbox. These programs are simple to use for simple applications, but why they do what they do. After you're done, you'll have additional excellent ideas of how to use sed in your various projects.
