Replacing _ with - from "SSH"

i got some folder names like name_surname in a folder and i wanna make them all name-surname, as there are like thousands of them i am not able to rename one by one, is there a command i can do this simplier?
thanks

 

There is no command to do that automatically. I suck with shell script, so I do things like that using php instead.

<?php
$dir = "/home/user/domain.ext/folder/";

if (is_dir($dir)) {
	if ($dh = opendir($dir)) {
		while (($file = readdir($dh)) !== false) {
			$files[] = $file;
		}
		sort($files);
		foreach($files AS $file) {
			$starts_with	= substr($file, 0, 1);
			if (($starts_with != ".")) {
				// . and .. are directives, other . files probably shouldn't be touched anyways
				$newname = str_replace("_", "-", $file);
				rename($dir . $file, $dir . $newname);
			}
		}
		closedir($dh);
	}
}
?>

PHP:

Something like that will probably do the trick for you; though, if the files you're looking to change are folders, then I don't know for sure.

 

I have shell script:

create rename.sh

#!/bin/sh

for name in $(find . -type d -print | sed 's/_/____/g')
do
if [ $name != "." ] ; then
oldname="$(echo $name | sed 's/____/_/g')"
newname="$(echo $name | sed 's/____/-/g')"
if [ "$oldname" != "$newname" ] ; then
echo "renaming \"$oldname\" to $newname"
mv "$oldname" "$newname"
fi
fi
done


save it and chmod to 755.

Ask your host to execute the shell script in the directory with ./rename.sh

 

thanks for the responds
