I have thousands of html files inside a folder. I want to replace the filename present inside another files. Say for ex:- fileName: 'abcd1234.html' is found inside another file say file2.html. Then I want to remove the last 4 digits of the fileName i.e,. 'abcd1234.html' => 'abcd.htm'.

Using below command you can replace string inside file. Use the same code and implement desired script for multiple files.

  sed -i 's/original/new/g' file.txt


sed = Stream EDitor

-i = in-place (i.e. save back to the original file)

s = the substitute command

original = a regular expression describing the word to replace (or just the word itself)

new = the text to replace it with

g = global (i.e. replace all and not just the first occurrence)

file.txt = the file name
