In vi editor,

:%s/value/rate/gi

g - globally changes it
i - user input to do if yes no if no

Using perl,

perl -pi -e 's/value/rate/g'

Using sed,

sed -e 's/value/rate/g' > newfilename
mv newfilename filename

sed -e 's///g' $i
done

1. perl -pi does not have to placed in a loop. It'll safely do so for all files on the command line

2. More important. Nobody protected the "value" against being part of another word, like "valued" or "invalueable" (give or take the typoes). The pattern to be replaced, if needed to be recognized as a word, needs to be anchored!

# perl -pi -e's/\bvalue\b/rate/g' file1 file2 file3 ...

Enjoy, Have FUN! H.Merijn

For multiple files in the same directory then,

perl -pi -e 's/value/rate/g' /*

Multiple files in multiple directory then,

find / -type f -name "*" -exec perl -pi -e 's/value/rate/g' {} \+

You can change * in change depends upon file pattern like *.log

You can also use xargs + find + perl -pi do change pattern in multiple files in different directories as,

# find -type f -name "*" | xargs perl -pi 's/value/rate/g'

hth.

Yet another way of replacing the desired string on multiple files within a directory. ex works on the existing file so that renaming or moving the original file is not required. Also this replaces whole words only instead of substrings like "valued".

# for i in $(ls ); do
> cat - <> %s/\/rate/g
> wq
> EOF
> done
