Question

In this case the character is “^“.

For example in the following format with 3 columns.

From:

1 cccc cccc
2 cta^<t cta^<tcc
3 ccc cccc^*
4 ^]a^*c^*c ^]a^*c^*c 

To:

1 cccc cccc
2 ctat ctatcc
3 ccc cccc
4 acc acc 

I’m quite sure this is possible with sed.

Answer 1

To match your demonstration input/output, it should just be s/\^.//g. To match the description, you need s/\^./\^/g (i.e., you’ve described it as removing the following character, but shown removing both the caret and the following character).
