Substitution/Addition
Hi I need to do the following substitution
I have to look for line starting with ABC and add 4 ":" before the first occurence of "+"in that line
Code:
Input
ABC:12:Lambert:C278472:1357:0:0:0:0:2:N::::N:9045123:NAP::+DEF
output
ABC:12:Lambert:C278472:1357.00:0.00:0:0:0:2:N::::N:9045123:NAP::::::+DEF

I have add 4 ":" before the first occurence of ' in the line only if i don't have a "+" in the line
Input
ABC:12:Lambert:C278472:1357.00:0.00:0:0:0:2:N::::N:9045123:NAP::'
Output
ABC:12:Lambert:C278472:1357.00:0.00:0:0:0:2:N::::N:9045123:NAP::::::'
