searches with the grep command

I am new to HPUX. I am having some trouble formulating a command within grep to search for a specific message as follows:  vx_nospace - /dev/vg02_eva/lvol4 file system full 

Is there anyone wiling to help? I know it needs to start with the grep command but no matter how I assemble the command, I cant get it to find "no_space" or "file system full"

Thanks in advance

Re: searches with the grep command

   Do you want to search in one file or in multiple files?

> [...] no matter how I assemble the command, [...]

   Some examples of failed attempts would have been more useful than
that.  With my weak psychic powers, I can only try to guess what you
might be doing wrong.

   One explanation for the first part of that would be that the message
shown says "_nospace", not "no_space".

pro3$ echo 'vx_nospace - /dev/vg02_eva/lvol4 file system full' >

pro3$ grep 'file system full' fred.txt
vx_nospace - /dev/vg02_eva/lvol4 file system full

pro3$ grep 'file system empty' fred.txt
pro3$

If you're looking for a fixed prefix and fixed suffix, you can use:

grep 'vx_nospace.*file system full' file
