Java sed through all subdirectories?
I found this awesome sed script here:

https://www.unix.com/shell-programmin...lace-text.html

Code:
sed -i '/MatchText/ s/ReplaceMe/REPLACED/' filename

Question though to save me manually doing this.

How do I do this from a root directory and then go through every subdirectory and run this?

Thanks

You will have to feed sed with filenames. You might want to use a preceding find doing that, piping it to sed. Test it on a subdirectory first to not break your system if something goes wrong.

Code:
find / ...your switches etc... | sed -i ...

Code:
sed -i '/MatchText/ s/ReplaceMe/REPLACED/' filename

This code just search and replace the contents inside the file. Exactly what you want to do ?

I hope you mean from a root directory not from the root directory as some posters have assumed.

Every file ending with php (*php) in every directory below a given location

so I execute it in /root then it will execute in
/root/home,
/root/home/astrocloud,
/root/home/astrocloud/unixNotes and so on

I have a single directory as
Code:
sed -i '/MatchText/ s/ReplaceMe/REPLACED/' *php

My 'the root' directory is also an 'a root' directory
as in before;

/root/home,
/root/home/astrocloud,
/root/home/astrocloud/unixNotes

Code:
find ./ -iname '*.php' -exec echo sed -i '/MatchText/ s/ReplaceMe/REPLACED/' '{}' ';'

Remove the 'echo' once you've tested and are sure it does what you want.

Or, totally paranoid code:
Code:
cd /root/home
find . -xdev -type f -name '*.php' -print | while read filename
do
       # Remove echo when tested thoroughly
       echo sed -i '/MatchText/ s/ReplaceMe/REPLACED/' "${filename}"
done
