I'm looking for a command where only the highest disk space usage mount will be shown. So The maximum %usage mount will be shown.
Running df -h

What you are looking for is:
df -h | grep -vw "^\/dev" | sort -k 5 -n | tail -n 2 | head -n 1
Output of df -h | grep -vw "^\/dev":

I'm trying to sort one of the column and keep the 3 lines header without any change.
How can I do it without manipulate to other file?
I tried something similar to the below:
head -3 file.rpt ; sort -nrk4,4 file.rpt | -
I suppose this doesn't really count as a csh answer, but:
sh -c '{ sed 3q file.rpt; sed 1,3d file.rpt | sort -nrk4,4; }'
In csh, you can do:
( sed 3q file.rpt; sed 1,3d file.rpt | sort -nrk4,4; )
You can do this:
head -3 file.rpt ; tail -n +4 file.rpt | sort -nrk4,4
-n: output the last X lines
+4: output starting with line 4. Hence skip the first 3 lines
use | to send the output of tail as the input to sort.
Result:

If we see the size of sdb2 is 39.5GB in fdisk whereas 1k in the lsblk output. What can be the reason for this?

I would like to add the date for each line of the df output.
I tried:
df -m | awk '{print `date +%Y-%m`";"$1";"$2";"$3 }'
... but it doesn't work.
How can I add the date?
Here is an alternative:
df -m | awk '{print strftime("%Y-%m"), $0}'
And here is the output from the command above:
$ df -m | awk '{print strftime("%Y-%m"), $0}'

And here is an alternative version, printing just the 3 columns you wanted on the OP:
df -m | awk '{print strftime("%Y-%m"), $1, $2, $3}' | column -t
And the corresponding output:
$ df -m | awk '{print strftime("%Y-%m"), $1, $2, $3}' | column -t

You may use this way:
df -m | awk -v dt=$(date "+%Y-%m") '{print dt "::", $0}'
We use -v dt=$(date "+%Y-%m") to execute date command in shell and pass it to awk in an argument dt.
If you want only first 3 columns from df command output then use:
df -m | awk -v dt=$(date "+%Y-%m") '{print dt, $1, $2, $3}'
A Perl solution.
df -m | perl -MPOSIX=strftime -alpe '$_ = strftime("%Y-%M ", localtime) . "#F[0..2]"'
Command line options:
-M : Load thestrftime() function from the POSIX module
-a : Autosplit the input records on whitespace into #F
-l : Remove newlines from input and add them to output
-p : Put each input record into $_, execute code and then print $_
-e : Run this code for each input record
The code updates $_ by concatenating the date (strftime("%Y-%M ", localtime)) with the first three columns (#F[0 .. 2]) of the input record.
So at the beginning of my script, I am defining "threshold," which has a number that isn't going to exist in the next part, (2) and a number that will exist in the next part (6). I'm having the result of running df -h to a file called dffile. My question, is how do I get grep in line 7 to search all of the variable "threshold" for the number that will exist in the file? It works if I have the 6 before the 2 in the variable, so it seems as if it's only searching the first number in it. Thanks!
#!/bin/bash
threshold=("2%" "6%")
df -h > dffile
grep $threshold dffile >> thresh
cat thresh | awk '{print $6}' >> finding1
LINES=()
while IFS= read -r finding1
do
find $finding1 -xdev -size +40M -exec ls -lah {} \; | head -n 10
done < "finding1"
The output of df -h on my test server is:
root#tstd0001:~/scripts# df -h
Filesystem Size Used Avail Use% Mounted on
udev 481M 0 481M 0% /dev
tmpfs 99M 616K 98M 1% /run

tmpfs 493M 0 493M 0% /dev/shm

/dev/vda15 105M 3.4M 102M 4% /boot/efi
tmpfs 99M 0 99M 0% /run/user/0
As you can see above, "2" from my variable, does not exist, whereas "6" does. My goal is to make grep find any number that matches a number inside the variable.
Let's consider that cat output_df is the output of your df -h command:
$ cat output_df
Filesystem Size Used Avail Use% Mounted on
udev 481M 0 481M 2% /dev
tmpfs 99M 616K 98M 1% /run
/dev/vda1 25G 1.3G 23G 6% /
tmpfs 493M 0 493M 6% /dev/shm
tmpfs 5.0M 0 5.0M 2% /run/lock
tmpfs 493M 0 493M 0% /sys/fs/cgroup
/dev/vda15 105M 3.4M 102M 4% /boot/efi
tmpfs 99M 0 99M 0% /run/user/0
Then you change the first part of your script in the following way:
thresold="2%|6%"
cat output_df | awk -v VAR=$thresold '{if($5~VAR)print $6}'
of course you will have to replace cat output_df by df -h in the final script.
This will give the output:
/dev
/
/dev/shm
/run/lock
Explanations:
thresold="2%|6%" is a regex that matches 2% or 6% you can generalize it to "2%|6%|X%|Y%|...|Z%"
You pass it as a variable to awk via -v VAR=$thresold
Then you command awk to print the 6th field when the 5th field does match the regex that you have passed to it via '{if($5~VAR)print $6}'
Then you can regroup everything without using intermediate files:
thresold="2%|6%"
for f in `df -h | awk -v VAR=$thresold '{if($5~VAR)print $6}'`
do
find $f -xdev -size +40M -exec ls -lah {} \; 2>/dev/null | head -n10
done
On my box it gives the following output:

Notes: 2>/dev/null this redirection is to remove all the permission errors by redirecting stderr to /dev/null (muting the stderr)
You initialize threshold as an indexed array,
threshold=("2%" "6%")
You then call grep with:
grep $threshold dffile
Since threshold is an array, to dereference all values in the array, you use the form:
${threshold[#]} ## which can be quoted to preserve whitespace in elements
When you deference the array as a normal variable, e.g. $threshold you return only the 1st element, e.g.
echo $threshold ## output '2%'
So before going further, you need to determine what you want to pass to grep, if you want to search for either 2% or 6%, then Allan has a nice explanation above. You can also construct the grep expression using printf -v, e.g.
printf -v gexp "%s\|%s" ${threshold[#]}
or to properly limit to the first 2-elements,
printf -v gexp "%s\|%s" "${threshold[0]}" "${threshold[1]}"
and then call grep with
grep "$gexp" dffile >> thresh
Let me know if you have further questions.

I want to omit the 1st line Filesystem kbytes used avail capacity Mounted on from the output.
I used df -k | tail -n+2 in linux to get exactly what i wanted, but in SunOs I get
zenvo% df -k | tail -n+2
usage: tail [+/-[n][lbc][f]] [file]
tail [+/-[n][l][r|f]] [file]
How can i achieve the Required output:

Note: No. of rows might change
I know it's an old thread, but the shortest and the clearest of all:
df -k | sed 1d
I haven't used SunOS but using sed you should be able to delete the first line like this:
df -k | sed -e /Filesystem/d
edit: But you would have to be careful that the word Filesystem doesn't show up elsewhere in the output. A better solution would be:
df -k | sed -e /^Filesystem/d
If you want to omit the first line of any result, you can use tail:
<command> | tail -n +2
So in your case:
df -k | tail -n +2
https://man7.org/linux/man-pages/man1/tail.1.html
What about:
df -k | tail -$((`df -k | wc -l`-1))
