It can be done from the command line - under a unix system
perl -pi.bak -e 's/searchpattern/replacestring/g' *.txt
will replace all occurrences of 'searchpattern' with 'replacestring' in the
all the *.txt files in the current directory
use
perl -pi.bak -e 's/searchpattern/replacestring/g' `find -name '*.txt'`
to do it to all *.txt files in all subdirectories too (note the find
command is in back quotes). These will also make backups of the changed
files (remove the .bak to stop this). See the perlrun manpage for exactly
what the options do,
