UNIX for Beginners Questions & Answers

How could I use the env command to change the enviroment variable GREP_OPTIONS so that grep is not case sensitive by setting it to "-i'?

So that the command:

Code:

grep a <<< A

Will produce the same output as

Code:

grep -i a <<< A

Any attempts/ideas/thoughts from your side? What would man env say?

Would

Code:

env $GREP_OPTIONS="-i"

work?


*EDIT:*
Actually I got

Code:

env GREP_OPTIONS=-i grep a <<< A

to work.

Code:

env GREP_OPTIONS=-i grep a <<< A
A

What happened when you tried it on your server? I would expect a syntax error from env $GREP_OPTIONS="-i"

Try:-

Code:

GREP_OPTIONS="-i"            # Assign the value to the variable
grep a <<< A                 # Test it

Does that help?

Looks like he sneak-edited after your question.

I'm so sneaky with my large *EDIT:* tag.

Note that your "large *EDIT:* tag", is exactly the same size as the rest of the text in your post (so I'm not sure what "large" means in this case).

Note also that anyone subscribed to your thread will receive notification by e-mail when a new post is added to your thread after the current contents have been read; but will receive no notice when you edit a post. And, if someone trying to help you is editing a response to one of your posts, there isn't much incentive to go back and look for changes in posts that have already been read -- unless you add a new post pointing out that earlier text has been modified.

Those of us who read a lot of threads in this forum and try to help out by answering questions appreciate it when new information is added by submitting a new post to the thread instead of by editing an existing post.
