Hi again,
Didn't read your thing and you said directory tree, you could get a list of
the files first:
Hello,
in PERL:
#!/usr/bin/perl
chdir "/directorytostartwith";
@files = system("find . -print");
foreach $file (@files) {
if (-f "$file") { ### If file is a text file
open(FILE1,"$file");
open(FILE2,">$file.tmp");
while (<FILE1>) {
s/My Little Text/Replaced With/g;
print FILE2;
}
close(FILE1);
close(FILE2);
system("mv $file.tmp $file");
}
This will replace all instances of My Little Text with Replaced With and
write it all out to FILE2 (mynewfile.txt). You can use regular expressions
also in the s///; structure...
