grep -w "string" equivalent

[Sup]

Hello,

I am using grep to search for a string. I want only rows with exact match, Is there a
"grep -w string" equivalent on HP?

[Marco Santerre]

gerp -w string should work fine on HP as well

Hi,

The '-w' switch only works with grep in HP-UX 11i. Here is a recent post asking a similar question:

hi,

If you want to grep for a string regardless of case: grep -i " some string "

Note the spaces before and after.

According to the man pages, there is no -w for 10.20 or 11.0 (and very little likelihood that the 11i version will be backported to 11.0, no possibility for the almost obsolete 10.20 systems).

# cat testfile
some text and search string
search string
search string and some text

Standard grep:
# grep "search string" testfile
some text and search string
search string
search string and some text

Syntax to get only exact line match
# grep "^search string$" testfile
search string

The "^" signifies the begining of the line and the "$" signifies the end and, therefore, only an exact match of "search string" (with no other text in the line) will be printed.

Tom,

"grep -w" allows you to search for a word. In other words, "string" preceded/superceded by white space and/or begin/end line.

The use of " string " will only match if the white space is a space, not if it is a .
