Tutorial

Search for all files in the directory below

$ cd ~/gren/test/data

$ gren abc
abc.rb:1:def abc
abc.rb:6:abc

Heuristic, case-sensitive

# The case-insensitive when all lower case
$ gren testcase
testcase.txt:1:testcase
testcase.txt:2:TestCase
testcase.txt:3:TESTCASE

# Character mixed capitalization is strictly Search
$ gren TestCase
testcase.txt:2:TestCase
$ gren TESTCase
Not found..

# If you would like to search case strictly, use --cs(--case-sensitive)
$ gren testcase --cs
testcase.txt:1:testcase

AND search in piles keyword

$ gren abc def
abc.rb:1:def abc

NOT

$ gren abc --not def
abc.rb:6:abc

OR

$ gren --or aaa --or bbb
aaa.txt:1:aaa
bbb.txt:1:bbb

Specify starting directory

$ gren ccc -d sub
sub/ccc.txt:1:ccc

Filter by filename

$ gren bb 
abc.rb:4:bb
bbb.txt:1:bbb

$ gren bb -f abc
abc.rb:4:bb

$ gren bb --if abc
bbb.txt:1:bbb
