I need a regular expression that will only match to the String if it ends with the target that I am looking for. I need to locate a file with a specific extension, problem is this extension also comes in other files. For example I have two files named
B82177_2014-07-08T141507758Z.ccf
and
B82177_2014-07-08T141507758Z.ccf.done
I only want to grab the first of these and my pattern is:
.*\.ccf
but this grabs both.
Any suggestions appreciated, I am a newbie to regular expressions.
Literal Characters and Sequences For instance, you might need to search for a dollar sign ("$") as part of a price list, or in a computer program as part of a variable name. Since the dollar sign is a metacharacter which means "end of line" in regex, you must escape it with a backslash to use it literally.
So, yes, regular expressions really only apply to strings. If you want a more complicated FSM, then it's possible to write one, but not using your local regex engine.
Use an end anchor ($
):
.*\.ccf$
This will match any string that ends with .ccf
, or in multi-line mode, any line that ends with .ccf
.
$ is used to match the end of the string. and can be used like
"string"$
like
xyz$
if you want to end with xzy
