egrep

[simanek]

Hi all,

I've been working on a simple egrep expression for about a day now and i'm hoping someone will have some more insight to it than I do. Basically, what I want my egrep expression to do is return the first letter of an environment variable called $NAME, which is actually an echo of 'whoami'. I would think that egrep ^. $NAME would work...but noooooooo. Any ideas out there? Thanks. Mike

Hi,
Why use egrep when u can use just the cut command....
whoami|cut -c 1
or
echo $NAME|cut -c 1
will give u the desired output....

Are you writing this egrep in script or is it a program written in c? If it is written in c, try using
getevn("LOGNAME&quotit will return the name of the user logged in. Then use a pointer to point to the first letter of the name.
