Need correct pattern at end of line
I have some data as below. I need correct it as result.

Data:
Code:
BG1:100+10++II
DG1:200+100+1234
DG2:300+200++II
CG1:200+100+1111
DG2:400+100++II
DG6:200+200+2345
DG2:400+100+2222

Result:
Code:
BG1:100+10++II
DG1:200+100+1234
DG2:300+200++1
CG1:200+100+1111
DG2:400+100++1
DG6:200+200+2345

Need to correct only line start with DG2 and end with ++II. Change ++II to be ++1.

Please help to correct with sed command.

Awk approach you may try

Code:
$ awk  '/^DG2.*II$/{gsub(/++II/,"++1")}1' file
BG1:100+10++II
DG1:200+100+1234
DG2:300+200++1
CG1:200+100+1111
DG2:400+100++1
DG6:200+200+2345
DG2:400+100+2222
