grep -w

andi_1 — Thu, 16 May 2002 16:27:38 GMT

Hi guys,

I am using 11.i and I used the following option in grep command -w to grep for a specific word. (grep -w)

I just found out that -w option doesn't exist on 11.0.
I don't have 11.0 - does anyone know what is 11.0 equvalent of grep -w?

Thanks a lot!

Hi

on a 10.20 box

:/home/H092AHE:Sleeves:>grep -w steve /etc/passwd
grep: illegal option -- w

Have checked man pages for grep -w ( nothing found)

Anyone else ?

Steve

Unfortunately, my code will be running on customer's systems, and I cannot rely that they have gnu grep.

Hi:

You can circumvent this by enclosing your string in quotes and providing whitespace, for instance:

# grep -e "^abc" -e " def " -e "abc$"

Nope, no -w in 10.20 or 11.0.
It's apparently a new feature of 11i. I don't think there is an equivalent option in HP-UX grep.

Hi (again):

Sorry, the example should have been:

# grep -e "^abc" -e " abc " -e "abc$" filename

Regards!

Hi all. I've got to say - Ugh!
I've been working on a script the past two days to help me pull the encrypted passwd entry from the respective system accounts in the /tcb/files/auth/* (trusted system dbase area)and pad those entries into field 2 of a temp/psuedo file that resembles the /etc/passwd file. (Basically, recreating the original /etc/passwd file from before the system was trusted.) I can then run this script on any system, extract and pad the necessary encrypted info, then take that output file and run it through the Crack5.0 engine.
Well, to make a long story short. I've been stuck on one particular area of the script. Everything about it worked fine except for one small thing. How to adapt for a search for a user who pulled up multiple matches. i.e. "uucp" would find "uucp and nuucp".
I knew the answer was with using regular expressions, but couldn't find the exact fit. And then I came accross this post today about "grep -w". In fact, I tried playing around with that earlier today, but made no headway. Basically, my problem was I was using the "/" from grep's metacharacter regular expressions. I took these out and it worked fine.

Thanks for the post.

Like I said - To make a short story long!
Just because it is a nice clean way to parse and pad this info I will attatch the script in the event someone wants to use it as they work with Crack. Or if someone can add it to the script archives.

I got this off the forums a while back. I'd give credit to who wrote it, however, it's not in the script nor do I remember ...

Hi Tom. That script is different from the one which I wrote for my needs completely. Now there are multiple ways to approach this. I worked out my script without seeing any others.
