Hi all

What do I do to get list of files that have tabs? How to do substitute the tabs with spaces?
Is there a way to do that in a perl script that traverse the directory structure and replace tabs with spaces?


my project has so many files it would be time consuming to do one by one!


Thanks
in advance!

#!/usr/bin/perl
 
$dir = "path";
 
use File::Find;
find(sub{push(@files, $File::Find::name) unless -d}, $dir);
 
foreach $file (@files) {
        open(FILE, $file);
        foreach $line (<FILE>) { push(@file, $line); }
        close(FILE);
 
        $data = join("", @file);
        @file = ();
 
        $data =~ s/\t/ /g;
        open(FILE, "> $file");
        print FILE $data;
        close(FILE);
}

From a prompt, change to the directory you want to start, then enter this:

If you don't want a backup, remove the .bak part
#Create a backup with extension .bak
find . -type f -exec perl -i.bak -pe 's/\t/ /g' \{\} \;
 
#Don't create a backup
find . -type f -exec perl -i -pe 's/\t/ /g' \{\} \;

Here's a sed version:
# find all files from here (.)
# copy filename to hold space
# substitute tabs to spaces
# if there was no substitution go on to the next file
# otherwise append the hold space to the pattern space
# generate the mv command
# execute and display it
find . -type f \
| sed -n '
 h
 s/[\t]/ /g
 T
 G
 s|\(.*\)\n\(.*\)|mv "\2" "\1"|p
' \
| sh -sx
