how can i split and take only the cmd part from it.
You can of course specifiy only the "cmd"-part in the option-string of ps like Aia has already suggested. If you need all three values you can split these in the shell:
If you use a read command to fill several variables (three in this case) the input to fill them (one line from the output of ps) will be split along word boundaries, so the first "word" goes to the first variable, the second word to the second variable. If there are more "words" in the output than there are variables the last variable gets the whole rest of the line.
So, this works because the first two values are always single "words" (character groups surrounded by blanks), only the last one isn't. It would not work if there would be several multi-word values involved.
I've noticed most of my postings here are because of syntax errors.

trace-cmd.dat - trace-cmd file format
DESCRIPTION
The trace-cmd(1) utility produces a "trace.dat" file. The file may also be named anything depending if the user specifies a different
output name, but it must have a certain binary format. The file is used by trace-cmd to save kernel traces into it and be able to extract
the trace from it at a later point (see trace-cmd-report(1)).

0x17 0x08 0x44
The next 7 bytes contain the characters:
"tracing"
The next set of characters contain a null '
