This week I did only a short post, I have a lot on my plate but wanted to keep the habit of writing These during my weekly train rides.

Anyway, I had to use grep today and realized that I had forgotten the parameters a bit. So here is a little refresher:

-v : Flips what the output grep will show you. If you search for lines that contain the word test just write:

grep "test"

If you want all the lines that don't contain the word test just use the -v Parameter.

grep -v "test"

-n : shows Line numbers

-r : searches the current directory and all subdirectories recursively

--include : useful if you want Limit your search to a certain file pattern or Type.

grep --include="pom.xml" "java.version"

Or

grep --include="*.txt" "Test"

Which searches in all txt files for lines containing the word test.

To save me some typing when need to search through my files for specific terms i have a function in my bash.rc:

function grin() {
 grep -r -n --include="$1" "$2"
}

So when i want to search my Java Project for all XML files containing the term java.version i just type:

grin "*.xml" "java.version"
