Splunk Search

Help with basic regex

Hi

Is anybody can tell me what is the goal of this regex?

| regex ImagePath="\\\\\\\\"

As far as I know, it seems to search a character chain delimited by 4 backslash?

Thanks

As @gcusello says, backslashes have to be escaped. The way regex works is that the strings are processed twice, so backslashes have to be escaped again, so to match to a backslash, you need four backslashes in the expression for each backslash you are trying to match to. This means that your expression is looking for a double backslash (\\) in ImagePath.

Hi @jip31,

we could better help you if you share a sample of your logs.

Anyway, 4 back slashes are often required wen in you logs you have a back slash that must be escaped to avoid that SPL interpretes it a control char.

Ciao.
