How can
grep G.*schema
give me the result: ${Gacntg_dt}""'"'
doesn't G.*schema say give me an unlimited number of characters between G and schema?

Grep uses regular expressions, not wildcards.
In a regular expression, * stands for 0 or more of the preceding character; a dot is matched by any character.
correct, that what i understood..
so shouldn't G.*schema mean 0 or more of any character between G and schema?
so for ${Gacntg_dt}""'"' i get the 0 or more characters after G but the string schema doesn't get considered as part of the match.
sorry, but i must be missing something...
Please use [code] tags for code, not [color].
Please post the exact code you are using as well as a sample input file.
Note that a search string containing wildcard cahracters should be quoted.
