One-line shell script for find and replace
An equivalent of the other find-replace, except it's a one-liner that generates no temp files, and is more flexible:
Or, to change matching files in a hierarchy:
perl -pi -e 's/find/replace/g' *.txt
Or, to change matching files in a hierarchy:
find . -name '*.txt' |xargs perl -pi -e 's/find/replace/g'
