Unexpected Exit on Grep.

[nyounker]

Initially I attempted a "grep" to search for a string inside a file using the -irl flags and found that the -L (lowercase) was not available but then tried the -n flag instead

Command executed

grep -irn "test" *

cash exits to windows prompt.

verification of error.

I don't know if this output will help and I'm not sure if there is an issue with an thirdparty .js, however I did test this exit with the following commands just to verify as well.. same result of exiting.

grep -irn "test*" *
grep -irn 'test*' *
grep -irn 'test' *

Thanks.

I'll try to resolve this issue.

Wow. I didn't mean to make a spectacle of that error. I really apologize and thank you for legien stepping up.. after a month later I realized when m$ saw your project they got scared. You put some sense into the world of m$ . You and everybody participating. so they released bash/ or if you are from windows \ mixed with ubuntu and unity. ... There is a lot more that needs to be done with this project, only because everybody noticed the hard cut that m$ tried to apply. someone is scared about this project and that means WE should keep on working on it.

[nyounker]

I would recommend some additional help as this issue is still unresolved and I think it is an important issue to solve no matter the statement of releasing bash for ms, as is no one has solved this issue. seems like a power play to me to deviate from the good work that is going on here.

[steveoh]

The whole project was not updated for a month. I had no time recently. So, in you want to resolve this issue: Go ahead.

@nyounker thanks for your kind words :)

@Legien sorry about that! I've been super busy in life recently and haven't had any time for OSS :(

Hoping that will change soon!
