How to replace ‘-u username -p password’ with new value in linux shell?

old value: 10.125.11.5:27017 -u username -p password
new value: 10.125.19.6:27017

I want to replace all the old value in *.py files (current directory folder and subdirectory) using shell,how to do?

seems sed or grep can not work with’-u’ or ‘-p’.

Answer

Suppose you have an inputfile with this content:

$ cat inputfile
10.125.11.5:27017 -u username -p password

After executing this:

$ sed -e "s,10.125.11.5:27017 -u username -p password,10.125.19.6:27017,g" -i inputfile

You get this input file:

$ cat inputfile
10.125.19.6:27017

That should help with your issue.
