How can I select and replace only those strings which are followed by \tab. for eg : my sequence looks like : string0 positive cd parent=string0 id =121 string0 string0 negative ef parent= string0 id =121 string0 I want it to look like char7 positive cd parent=string0 id =121 string0 char7 negative ef parent= string0 id =121 string0 I want to replace string0 by char7 but only for those followed by \tab i dont want to replace the string0 in parent and in that id I am very n (HowTos)
