how to remove this annoying character?

Path Finder

In my log file there at the end of a file there is substitution character \x1A, here is the file with that character. I've tried following:

props.conf
SEDCMD-stripsub = s/\\x1A//g
SEDCMD-stripnull = s/\\x00//g

For null characters \x00 it works perfectly fine, but not the substitution character. Any suggestions how to get rid of it?

You shouldn't be escaping the \. If you want to remove a character with hex code x1a, you should use s/\x1a//g. When you see \x1A in the actual raw event, that's simply because Splunk substituted the non-printable character with a printable character sequence. I have no idea why the second one worked, unless your raw data contains the printable string rather than the null character itself.

I'm confused - just to clarify, does the second SEDCMD (stripnull) work but the first one doesn't?
