Unit Tests

cargo run tests sample.text

Run

cargo run someStringToSearch someFileName

cargo run the sample.txt # shows 2 matching lines

cargo run t sample.txt   # shows 4 matching lines

cargo run \  sample.txt  # match all lines with spaces, in this case all lines except the new line

Executable from anywhere

cargo build --release
cd ~/code/rust/grepy/target/release
./grepy run t sample.txt                                # same as # cargo run t sample.txt
~/code/rust/grepy/target/release/grepy run t sample.txt # same as # cargo run t sample.txt

so.... just add rust to your path and you can then run from anywhere

notice current permissions

these are fine and the same as chmod +x grepy -rwxr-xr-x 2 whoami staff 327K Aug 13 12:54 grepy

./grepy com some/path/to/some/file

it will create a binary file

./target/release/grepy

This binary is completely self-contained, so you can move or copy it to somewhere else on your computer.

Run from anywhere

This is my first rust lang answer on stack overflow
