searches with the grep command

robert4604 — Thu, 09 Nov 2017 16:59:03 GMT

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

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

   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' >
fred.txt

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
