If you use the -i
option you need to provide an extension for your backups.
If you have:
File1.txt
File2.cfg
The command (note the lack of space between -i
and ''
and the -e
to make it work on new versions of Mac and on GNU):
sed -i'.original' -e 's/old_link/new_link/g' *
Create 2 backup files like:
File1.txt.original
File2.cfg.original
There is no portable way to avoid making backup files because it is impossible to find a mix of sed commands that works on all cases:
sed -i -e ...
- does not work on OS X as it creates -e
backups
sed -i'' -e ...
- does not work on OS X 10.6 but works on 10.9+
sed -i '' -e ...
- not working on GNU
Note Given that there isn't a sed command working on all platforms, you can try to use another command to achieve the same result.
E.g., perl -i -pe's/old_link/new_link/g' *
