Linux basic commands grep

Raja PLECI: JSF 2.0 tutorial with Eclipse and Glassfish

The file is in Arabic script, but the search on command line does not show that search string. How can we grep for patterns in an Arabic file. Can we read the binary file and search for a particular pattern there. Is there any website/ tutorial on using grep with Arabic script. When I type the pattern to look for, it shows nothing.

So the command above will produce whole 4 line of each record, which contain dd:uvw. ** answer2 **
How to check value of aa: in the record which contain dd:uvw. To show only lines with aa: and their values, we can simply add subsequent grep:
cat file | grep -B3 ‘dd:uvw’ | grep ‘aa’
and that’s it. Cat file | grep -B3 ‘dd:uvw’
-B3 tells grep to show line that matches our pattern and 3 lines Before (you can change this number if you want, you can use -A4 to show 4 lines After).

When searching through big files, grep may take a while to complete its task. Typically you may be using already a specific word that you want to be matched. The only downside is that regular expressions can not be used. By using the -F (fixed strings) option this can be dramatically improved.

Sample outputs:.

Not sure whether anyone will even see mine 🙂 anyway, there is a nifty trick I’ve come up with recently – a way to display configuration files without all the junk (comments, empty lines, etc). Try it – much easier to read. This is one terribly long trail of comments.

The format is s/search/replace/ so if I wanted to replace the word cat with dog I would use s/cat/dog/ where it matches cat and replaces it with dog. This gives you back just the number without any tab/space padding on either end. The first one says if there is any empty space at the start of the line then to delete it. Using the two forward slashes at the end says replace it with nothing or delete it. The second rule says if there is any space at the end then delete it.

Any one can help that’d be great. I was able to get everything I needed but when it comes down to getting only “x” amount of records to print in each file I’m lost. Below is what i have for a script right now. I am not sure if grep can do this or not but I have a script and needed to go through an xml file and take the basic record count and divide it into threes.
