If you state that _ and - are word separators and you want the first 5 words from the string contained in a variable; no your code cannot reliably guess at how many separators in the first 5 words are not separators.

If you know that the part of the filename that you do not want always ends with three occurrences of _string, you could use:
Code:
File="010020004_S-TOR-Sort-CAS_P_20170519_121504_0007.TXT"
FilePart=${File%_*_*_*}
echo "$FilePart"

with any shell that performs the variable expansions required by the POSIX standards.

Note also that there is a huge difference between using the command name echo and the command name Echo in any system that conforms to the standards. Utility names are case sensitive and there is no definition in the standards as to what a command named Echo will do (if such a command exists on your system).

Also note that there is no need to use echo and command substitution in the assignment of the variable expansion.
