Sed Command - - -How to change part of the name of multiple files
I have a doubt, as sed command is a stream editor, use to perform edits on stream of data. Given a file name to process sed will perform search and replace on all lines of file and sending modified data to standard output.
What if we want to replace multiple files together. For example i have a directory which contains 100 files and i want to replace many of them starting with particular string and i want extension to be same.
I want to change ab123_12 with some string say hello , how can i do this with sed.
Kindly provide your inputs.
Many thanks in advance.
