Any awk one liner to print df output?
Hi,

OS = Solaris

Can anyone advise if there is a one liner to print specific output from a df -k output?

Running df from a command line, it sometimes gives me 2 lines for some volume. By re-directing the output to a file, it always gives 1 line for each.

Below is an example output, I've modified some of the volume names for confidential reason.

Code:
Filesystem            kbytes    used   avail capacity  Mounted on
server01:/vol/vol_01/01 319815680 246331968 73483712    78%    /nas_mnt/server01/vol_01/01
server01:/vol/vol_02/02 284164096 255495160 28668936    90%    /nas_mnt/server01/vol_02/02
server01:/vol/vol_03/03 8388608 7686776  701832    92%    /nas_mnt/server01/vol_03/03
server01:/vol/vol_04/04 12066816 6133128 5933688    51%    /nas_mnt/server01/vol_04/04
server01:/vol/vol_05/05 752877568 394102812 358774756    53%    /nas_mnt/server01/vol_05/05
server01:/vol/vol_06/06 3145728 2591832  553896    83%    /nas_mnt/server01/vol_06/06
server01:/vol/vol_07/07 6266880 5037936 1228944    81%    /nas_mnt/server01/vol_07/07

Can anyone advise if there is any way to print the lines matching where the capacity is >= 80%?

How do I change the one-liner below to print the whole line?

Code:
 
awk '{ print $5 }' /tmp/df.out | awk -F% '$1 >= 80 { print $1 }'

Ideally, I would want to convert the kbytes, used and avail to GB as well but the first one will give errors as it is the df header.

FYI, I am using df -k because some of my Solaris servers do not have the df -h so I need a df -k output but I want to convert them to GB via awk.

Any advice much appreciated. Thanks in advance.

Hi Yoda,

That works alright, anyway I can use awk instead?

If not, any way I can have the kbytes, used, avail to GB, i.e. have $2, $3, $4 divided by 1024/1024?

Hi,

Tried that but didn't work.

\| is a GNU extension. There is no alternation operator in standard basic regular expression grammar. Outside of GNU (and Busybox, probably, since they explicitly model their implementation on GNU tools), I don't believe that will work anywhere.

Portable equivalents:
Code:
grep -e '[89][0-9]%' -e 100% file

... and ...
Code:
grep '[89][0-9]%
100%' file
