A grep implementation in golang. A command line program that implements Unix command grep like functionality.
The program has the following features.
To install you can use makefile or build using commands
make build
OR
go build main.go
To run game,
make run
OR
./gorep // after building
To run tests
make test
OR
go test ./... -v
Usage: ./gorep [OPTION]... [PATTERN] [FILES]...
Search for PATTERN in each FILE.
Example: ./gorep 'hello world' menu.txt main.txt
- Search for a string in a file
$ ./gorep "search_string" filename.txt
filename.txt:L2:I found the search_string in the file.
- Search for a string from standard input (using pipe)
$ ls | ./gorep foo
will produce
barbazfoo
food
- Write output to a file instead of a standard out for example,
$ ./gorep -o out.txt lorem loreipsum.txt // It will create an out.txt file with the search output.
$ cat out.txt
lorem ipsum
a dummy text usually contains lorem ipsum
- Search in multiple files.
$ ./gorep "test" test1.txt test2.txt
tests/test1.txt:this is a test file
tests/test1.txt:one can test a program by running test cases
tests/inner/test2.txt:this file contains a test line
- Or search for a string recursively in any of the files in a given directory.
$ ./gorep -d tests test
tests/test1.txt:this is a test file
tests/test1.txt:one can test a program by running test cases
tests/inner/test2.txt:this file contains a test line
