Every now and then, I have a reason to replace all occurrences of a certain string in every file in all sub-directories. Geneerally this is for scripts that will run on a Linux server, and finding a program to do this on windows seems hard!.
Now its possible on Linix using a combination of Find and Sed, using exec or xargs and also possible with grep and sed, or writing a simple script. However I can never remember the exact syntax and the best way.
For find
find ./ -type f -exec sed -i ’s/string1/string2/g’ {} ;
works well
I was really glad to find this useful command ‘rpl’ that replaces strings. Easy to install on Ubunto just
sudo apt-get install rpl
e.g.
rpl -pR "old" "new" *
