Like a cut(1)
that allows reordering of fields.
UNIX cut(1)
is a great utility, but I found myself wanting to often reorder fields. This cmd utility attempts to be similar in terms of API to cut(1)
but respects the given column order. This is especially useful when wanting to sort data numerically.
npm install -g cut-ordered
echo 'a b c' | cut-ordered -f 3,2,1 -d ' '
c b a
echo 'a b c' | cut-ordered -f 3,1 -d ' '
c a
The line parser is a custom compiled function: while gross-looking this means it should execute as quickly as possible (currently about 1.3x as slow as cut(1)
). To compare the two:
npm run bench
