Hi Admins,

M preparing a shift which gives VG details with free space etc.

In some servers some VGs are deactivated.

If i run my script m getting correct output to a file..but without the error message for deactivated VGs.The same error message is displaying after i run the script but not in output file.

$ ./freecalc
vgdisplay: Volume group not activated.
vgdisplay: Cannot display volume group "/dev/vgtest1".
$ more /home/uxgsmc/disk.out

/dev/vg00 has total 2 disks
/dev/dsk/c2t0d0s2
/dev/dsk/c2t2d0s2
Used space is 71568 MB
Free space is 66608 MB

I want to include those message in output file..

Plz help on this

Hi Himacs:

All good Unix code uses STDERR (FD #2) to report errors and STDOUT (FD # 1) for "standard", normal output.

Thus, simply do:

# vgdisplay > myfile 2>&1

...which redirects STDOUT to 'myfile' and redirects STDERR to the same place as STDOUT which now is 'myfile'.

Regards!
