[SOLVED] how to replace continuous pattern in text

Issue

i have text like 1|2|3||| , and try to replace each || with |0|, my command is following

      echo  '1|2|3|||'  | sed -e 's/||/|0|/g' 

but get result 1|2|3|0||, the pattern is only replaced once.

could someone help me improve the command, thx

Solution

This might work for you (GNU sed):

sed 's/||/|0|/g;s//[0]/g' file

or:

sed ':a;s/||/|0|/g;ta' file

The replacement needs to actioned twice because part of the match is in the replacement.
