code differences

I am interested to know why the ip are not listed with the -w option in grep
It works fine on my ubuntu 8.04 version(bash) but not in my HP-UX Release 11i (ksh)

mysys:/tmp/x->find . -type f -print | xargs grep -n -w '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'
mysys:/tmp/x->find . -type f -print | xargs grep -n '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'
./test/myfile.txt:2:this line contains ip 192.162.110.2
./test/myfile.txt:3:mutliple ip on single line 193.254.110.23 ans with the 10.10.10.1
./test/testfile2.txt:2:192.23.345.45
./test/testfile2.txt:3:includes ip configured to match teh currenmt 10.11.101.23

what version of grub is on both machines?

[gits]

do you mean grep? just wondering ... :) .... to get the version of grep you might use:

grep -V

gives you something like:

GNU grep 2.5.4

There was no version information attached to the grep.
but the STANDARDS CONFORMANCE
grep: SVID2, SVID3, XPG2, XPG3, XPG4, POSIX.2

hp:/preyan->grep -V
grep: illegal option -- V
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] -e pattern_list...
        [-f pattern_file...] [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] [-e pattern_list...]
        -f pattern_file... [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] pattern [file...]

the grep command works as desired in my linux box with the bash shell
but i am interested to know why this is not the same in the HP-UX Release 11i
though it is complaint ot the standard.

@micmast
Just got curious on this reply, how does grub play a role in this issue ?
or was that a typo

[gits]

perhaps:

grep --version

works to get the verision info? i suspect the -w option could be the problem - just a guess based on the last output you posted?

kind regards

@kaarthikeyapreyan
it doesn't, it should be grep :)
my typing is worse then your average joe, sorry for that :)

[kaarthikeyapreyan]

@gits
Yes it is the problem and --version is also an illegal option
-w does not work as expected in this grep.
this does not integrate any version information.

[gits]

ok ... since it just seems to be clear that it works differently on both of the machines i would suggest to just avoid the -w option and use a regExp instead ... or have a look here at a similar question at the HP resource center

kind regards
