Hello.
Thanks for the note.
Here is additional information:
Sample file excerpt...
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 131072 38912 71% 4261 32% /
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/inputlv 255328256 118925432 54% 564 1% /IPW/input
=46rom this example, I want to evaluate the column labeled %Used for
values greater than 60% and if that value is greater than 60%, I then
want to write that entire line, (/dev/hd4 131072 38912
71% 4261 32% /
) out to a text file that will be emailed out to report on filesystems
that are now at a capacity of 60% or greater.
I already have the script written to create the original df -k output
to a text file and create the email generation. I just need to have
help evaluating the correct values in the original df -k output file
and then creating the new file containing entries of all filesystems
that are at or above 60% capacity.
Does this help clarify my question?
Thanks again,
Karin Walike
