What Others Think

You have "data" in a fixed format. That seems to be a job for awk or sed. The delimiters are different: first space, then semicolon, so I'll use sed. . sed 's/^[^ ]\+ \([^;]\+\).*/\1/' input.txt > output.txt . sed s/search/replace/ . ^ beginning of line [^ ]\+ multiple NOT space characters (a space) \( \) remember this for later [^;]\+ multiple NOT semicolon characters .* the rest of the line \1 the text we found between the \( \)
