how to format a grep command

Hello

I am trying to use the grap command to locate the following phrase in a file:
"file.php\tDebug: one two three"

Note that \t denotes a tab (whitespace) and not the characters \ and t

I am encountering the following 2 problems:
1) there is a perido between "file" and "php" which needs to be encoded somehow
2) there is a tab between "php" and "Debug" which needs to be encoded somehow

I would appreciate it if someone could some me what the correct syntax for this command should be

In a more general note, I would appreciate if someone could refer me to a manual on using grep, including character escaping

regards and thanks in advance

Put the whole thing in double quotes and put a backslash in front of the dot. For the tab, just hit the tab key.

Thanks Perderabo
I will follow your advise
