问题
I need to replace a list like this:
105164 25
105164 26
105164 29
105496 1
105496 2
To
105164_0025
105164_0026
105164_0029
105496_0001
105496_0002
Something like (\w)([0-9]+) to _$1 but how to do the left zero padding?
回答1:
[ ]([0-9]+) to _$1 --do your first replace
_([0-9])$ to _000$1
_([0-9][0-9])$ to _00$1
_([0-9][0-9][0-9])$ to _0$1
Kind of a cheat method but that's the only way I can think of.
回答2:
You can do in two passes:
first pass:
Find what: (\d+)$
Replace with: _0000$1
second pass:
Find what: _0*(\d{4})$
Replace with: _$1
