I want to find and replace one string, finding is tricky for example if there are inputs values like below,
boks_hjimn_cat, boks_hmm_dog, boks_go_rawst
I should replace boks_ begin values with addition value appended, but boks_ begin values and rawst end values should not be replaced. The output should be like this in the replaced file.
I just gave example of 3 values but this file more than 200 pattern of this type.
Please let me know if there is a combination of find, awk or sed commands.
