bash - Sorting lines in a file using a specified order in another file -

given file1

a b c d e f h n o p q j k l m 

and file2

3 1 0 1 2 

i sort file1 in order given in file2. output should be:

n o p q e f h j k l m b c d 

basically, how can add file2 in front of file1 prefix column, , sort column, remove prefix column?

the answer here close match, doesn't answer question.

paste friend:

paste f2 f1 | sort | cut -d$'\t' -f2- 

in steps:

$ paste f2 f1        # join files 3   b c d 1   e f h 0   n o p q 1   j k 2   l m $ paste f2 f1 | sort # sort them 0   n o p q 1   e f h 1   j k 2   l m 3   b c d $ paste f2 f1 | sort | cut -d$'\t' -f2-  # remove 1st column n o p q e f h j k l m b c d
