Linux Shell script not working on SunOs 5.10

Well the script in post#1 works on Solaris 10.
However there are some risks e.g. when the order of "df -h" would differ from "df -Pk" (though it never did in my tests).
I suggest the classic shell method: a while loop that reads the columns into distinct variables. Simple, efficient, safe.

Code:

df -kP |
while read fs x x x used x
do
  case $fs in /*)
    echo "File System $fs used space is $used"
  ;;
  esac
done

Perhaps even a simple

Code:

df -k

is hung on your Solaris system?

@hiten11 A little late but please be aware LinuxQuestions has a dedicated Forum for Solaris related questions here.

In any case, note that there is a very simple way to make your original script working almost as is on Solaris. Just add the following line as first instruction, just after the shebang:

Code:

PATH=$(getconf PATH):$PATH

and that's it. This command is setting the PATH for the shell and other commands to run POSIX compliant utilities. Under Solaris, POSIX compliant utilities are not necessarily the default ones. After setting the PATH, the df and awk commands will behave the way you expect.

You script would still be non portable as it uses bashisms but this is not a problem as Solaris has been bundling bash since more than a decade.
