Strange behaviour of grep in SunOS

Hi
I ahve 2 files with below content:
Code:
cat file1
FILE3
test1
test2
cat file2
file3
ghg
test1
test2

i want to use file1 as pattern file and find out the missing strings in file2.(i.e ghg in this case regardless of c ase)

I have tried:
Code:
grep -i -v -f /path/file1 /path/file2

But it gives:
Code:
grep: illegal option -- f
Usage: grep -hblcnsviw pattern file . . .

My operating system is:;
Code:
SunOS  5.8 Generic_117350-60 sun4u sparc SUNW,Ultra-Enterprise

Thanks

I saw this in the man pages of grep for SunOS: SunOS man pages

Code:
/usr/bin/grep [-bchilnsvw] limited-regular-expression [filename ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] -e pattern_list ... [-f pattern_file] ... [file ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] [-e pattern_list ...] -f pattern_file ... [file ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] pattern [file ...]

Would this be of any help?

Thanks it works:

ghg

SunOS has different versions of the same utility for backwards compatibility; for example some of these are found in /usr/bin, usr/xpg4/bin, and /usr/xpg6/bin.

One notable weird exception: awk. The only modern awk is not awk, but nawk.

understand Man page

[QUOTE=balajesuri;302590954]I saw this in the man pages of grep for SunOS: SunOS man pages

Code:
/usr/bin/grep [-bchilnsvw] limited-regular-expression [filename ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] -e pattern_list ... [-f pattern_file] ... [file ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] [-e pattern_list ...] -f pattern_file ... [file ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] pattern [file ...]

Unable to understand the above code.Please mention a easy way to understand MAN pages in UNIX.

ThanksSmilie

The quick-and-dirty way to understand such things is to read them:
Code:
/usr/bin/grep [-bchilnsvw] limited-regular-expression [filename ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] -e pattern_list ... [-f pattern_file] ... [file ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] [-e pattern_list ...] -f pattern_file ... [file ...]
/usr/xpg4/bin/grep [ -E | -F] [ -c | -l | -q] [-bhinsvwx] pattern [file ...]

See the difference between different greps now, how some support different things?
