Well believe it or not GREP is your friend, it will save you lots of time, as long as you use it wisely. This article will hope to show you how to use it, and help you get the full use out of it.
grep can be used to do a search for a word or pattern of words, with a set of characters such as a file. When using grep to search files, an example would be, any matches to the word or characters you
specify. Then the findings are printed as a complete line in which the grep found in the files in the file which the search occurred.
Example : Lets say you have a file called
chuckie.txt and you are looking for the word FreeBSD within that file you would do.
To search for any listing of 'freebsd', you could type:
grep freebsd chuckie.txt
Once it finds something, it would show the text within the file on the screen.
grep is case sensitive by default, If you wanted to find all chances of the word freebsd in the
chuckie.txt files you would do the following, by adding a -i to the command line, shown below.
grep -i freebsd chuckie.txt
Lets say we have several .txt files that we wish to search for the word freebsd, to do this without having to open each file you would do the following command line.
grep -i freebsd *.txt
Ok, lets say we are looking
for dog and want to see every file shown on the machine that has the word dog listed in it, to do this you would do the following. First you will need to goto the root directory, to do this.
cd \
grep -R dog * |more
The |more at the end will stop the text one screen worth at a time, so you can read it, otherwise it might go by so fast you couldn't read the screen, thus missing what you might be looking for.
