Shell Programming and Scripting

Hi friends,
i am using the following grep command for exact word match:

Code:

 >echo "sachin#tendulkar" | grep -iw  "sachin"
output: sachin#tendulkar

as we can see in the above example that its throwinng the exact match(which is not the case as the keyword is sachin and string is "sachin#tendulkar". i think it is ignoring the substring before # and taking it as a exact match). is there any other command to find the exact search?
thank you in advance

shell: ksh88

Try -x for whole line match.. # is not a word character and therefore sachin is considered a word...

but that option does not seems to be working in ksh88

Code:

> echo "sachin#tendulkar" | grep -x  "sachin"
grep: illegal option -- x
Usage: grep -hblcnsviw pattern file . . .

i dont know what is the problem. is there any other way out?

you should use -o option for the exact pattern matching string

Code:

 > echo "sachin#tendulkar" | grep -o "sachin"

Please try this one.

@neelmani:
Use /usr/xpg4/bin/grep instead of grep

@scrutinizer : thanks its working. may i know the reason behind writting the full path?

/usr/bin/grep is not the POSIX compliant version on Solaris. POSIX compliant versions of utilities can be found in /usr/xpg4/bin or /usr/xpg6/bin
