grep command with combined variables in Ksh
Hi,
I'd like to grep two variables that are seperated with one space in ksh.
var1="Feb"
var2="09"

I tried to grep "$var1 ""$var2" /usr/file

It turn into grep Feb 09 /usr/file when it runs.

I got error.

Can some one help me with this one?

Thanks a lot for your help!

Why dont you try putting the variables together inside the double quotes instead of quoting them seperately? That will get you the grep command that you are looking for.

Or if you want to find both strings even when they are not right next to each other, pipe your greps together, like this:

grep Feb /usr/file | grep 09

This would find it even if the exact text isn't Feb 09 but both pieces are on the same line. For example, it would find "Today is Feb 09" but it would also find "My grandfather was born in February 1909". The method blowtorch suggested is better if you want to find just the exact string Feb 09.

Ok, I just noticed the line where you said they need to be separated by one space, so I guess blowtorch's method is better. But I might as well leave this here for more information since I bothered to type it in. :-)

Too many quotes.

grep "$var1 $var2" filename
