fnd

https://secure.travis-ci.org/humanfromearth/fnd.png?branch=master

A golang implementation of the popular find unix utility.

The main reason I coded this is because I find myself writing this a lot:

find -iname "*x*"

Instead I want to write:

fnd x

That's the whole philosophy really.

Install

go get -u github.com/xarg/fnd

Example

fnd <pattern> <path>

$ ls .
dir1
$ fnd # just list the directory
./dir1
$ touch dir1/y; touch ./dir1/2; touch ./dir1/x2 #create a few example files
$ fnd y
./dir1/y
$ fnd 2 # matches *2*
./dir1/2
./dir1/x2
$ mkdir -p dir2/y
$ fnd y ./dir1 # search just in ./dir1
./dir1/y

Regexp example

fnd -e <regexp> <path>

$ fnd -e x$ # ends with x
$ fnd -e ^x # starts with x
./dir1/x2
$ fnd -e y$ ./dir2 #search regexp in a directory
./dir2/y

Benchmarking

$ go test -c # this creates fnd.test. This step is required in order to use it with the profiler.
$ ./fnd.test -test.bench="." -test.cpuprofile="fnd_cpu.prof" -test.memprofile="fnd_mem.prof"
