Hi,

I intend to do a search and replace for specific words for files under a directory (inclusive of subdirectories).

I know how to do that file by file using sed
and redirect it to the original file. But now, I need to search for multiple files and update accordingly.

Please help.

Thanks in advance.

Maybe a for loop with a variable for your filenames generated by ls?

foreach file (`ls`)
do
whatever $file
done

for pattern in "string1" "string2" ; do
for file in `find /full/path/root/to/search/ -exec grep -l $pattern {} \;` ; do
ls -l $file ;
sed -e 's/$pattern/newpattern/' $file > $file.tmp
mv $file.tmp $file
done ;
done | mail user@domain.com
