One of the renowned search tool on Unix-like systems which can be used to search for anything whether it be a file, or a line or multiple lines in file is grep utility. Due its varying functionalities, it has many variants including grep, egrep (Extended GREP), fgrep (Fixed GREP), pgrep (Process GREP), rgrep (Recursive GREP) etc. Main thing that remains to be investigated is what are the differences between the three main variants i.e.
In case of egrep, even if you do not escape the meta-characters, it would treat them as special characters and substitute them for their special meaning instead of treating them as part of string.
Like here, egrep searched for “file” string when the meta-characters were not escaped as it would mean by the meaning of these characters. Fgrep or the Fixed grep or grep -F is yet another version of grep which is fast in searching when it comes to search for the entire string instead of regular expression as it doesn’t recognize the regular expressions, neither any meta-characters. Fgrep searches for complete string and doesn’t even recognize special characters as part of regular expression even if escaped or not escaped.

We’ve already covered some practical examples of grep command you can read them here, if you want to get more out of grep command in Linux.
If you find any other differences between these three versions of grep, do mention them in your comments. Currently a Computer Science student and a geek when it comes to Operating System and its concepts. Normally, most of us do not use Calculator in Windows, but even if we do, we use it for small calculations. Now, I will tell how to use built-in Calculator of Windows to perform data calculations, to find answers to the questions that were asked at the beginning.
Using this option, you can find difference between two dates in terms of years, months and days. It is very easy to navigate through years and months in Calculator and fill the fields as specified. If you want to know what was the day which is 5 years, 4 months and 3 days before today’s date. Make some interesting and fun calculations using the Windows Calculator and let us know through comments.
Sridhar is a Software Engineer who loves to stay updated with developments in the world of technology. It is very vast in functionality which can be attributed to the large number of options it supports like: searching using string pattern, or reg-ex pattern or perl based reg-ex etc. But these variants have minor differences to original grep which has made them popular and to be used by various Linux programmers for specific tasks. This version of grep is efficient and fast when it comes to searching for a regular expression pattern as it treats meta-characters as is and doesn’t substitute them as strings like in grep, and hence you are freed from the burden of escaping them as in grep. Apart from difference in the set of regular expressions used, and speed of execution, rest command line parameters remain same for all the three versions of grep and even instead of “egrep” or “fgrep”, “grep -E” or “grep -F” are recommended to be used.

Have 1+ years of experience in Linux and currently doing a research on its internals along with developing applications for Linux on python and C. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. Click on Calculate and the result is displayed in years, months, days and in entire days also. For example, you have come across “Offer is valid till 65 days from now!” Then, it is not so easy to find the accurate day and date after 65 days from now.
Then, you need to select Subtract and enter 5 in Year(s) field, 4 in Month(s) field and 3 in Day(s) field.
But when the special characters were escaped, then instead of treating them as part of string, grep treated them as meta-characters and searched for words “file” or “gile” in the file. You can carry out conversions from one unit to other – like from feet to meters, currency conversions and more. The Calculator gets expanded which allows us to perform additional tasks, including calculations on Date. Suppose, you want to find out how old you are, then you can select your date of birth in From field and today’s date in To field. You can be free from using third party software to get answers to these questions, when you know how to use the Calculator in Windows.
It shows that, after 65 days from today (Day on which article was written) is Saturday, March 28, 2015. Apart from basic calculations, it has some unique features like finding the difference between two dates and finding the day that would come after 65 days from now and so on.
