Hi

use

diff

if you wanted to know if they are one and same, then use

cksum - if both has similar output numbers the files are identical

Hi Miquel:

While 'diff' and 'cmp' will compare and optionally report the differences of ASSCII text files, all that will be returned for binary files is whether they differ or not.

If two binary files differ, 'diff' will simply note:

"Binary files f1 and f2 differ"

The best way to valid the "sameness" of any two files is to compare their 'cksum' value:

# cksum /stand/vmunix
2335558063 10340004 /stand/vmunix

The first number is the computed cksum; teh second is the number of octets.

Regards!

Hi Miquel:

On each server, do:

# kmtune -l > /tmp/kmtune.$(hostnmae)

Then:

# diff -bC1 /tmp/kmtune.host1 /tmp/kmtune.host2

...to show lines in context...or simply:

# diff /tmp/kmtune.host1 /tmp/kmtune.host2

See the manpages for 'diff' for more information.

Regards!

diff /stand/system /stand/build/system to see any changes you have made, but next time just use Sam to make kernel changes that way you can see the current value and the pending value before you reboot your server

On HP-UX you can use:
#diff file1 file2

Try as,

nm /stand/vmunix > /tmp/kernel1.symbol
nm > /tmp/kernel2.symbol
diff /tmp/kernel1.symbol /tmp/kernel2.symbol

Another way as,

strings /stand/vmunix > /tmp/kernel1
strings > /tmp/kernel2
diff /tmp/kernel1 /tmp/kernel2
