To Extract words from File based on Position
Hi Guys,
While I was writing one shell script , I just got struck at this point.
I need to extract words from a file at some specified position and do some comparison operation and need to replace the extracted word with another word.
Eg : I like Orange very much.
I need to replace the word starting from 8th position till 15th ( Here 'Orange ') and needs to replace it with 'Apple ' .
I am looking for a command for this.
Will Sed command work if the word position is the only known parameter?
Looking for your suggesions
Thanks
