Merge multiple lines into one line using shell script

I have a text file like inputfolder/abc.txt

Input (Below is just an example - the actual file will have many lines which will vary everytime):

abcdefgh~

asdfghjkliuy~

qwertyuiopasdfgh~

..........

Every line ends with '~' and I would like to merge all the lines into one

Desired output:

abcdefgh~asdfghjkliuy~qwertyuiopasdfgh~...............

How can I merge all the lines into one line using shell script? (I don't want to add any extra character)

Once all the lines are merged, the file should be moved to another folder.
Example: OutputFolder/abc.txt

You can solve this with tr and the delete parameter (delete the new line characters).

$ cat inputfolder/abc.txt 
abcdefgh~

asdfghjkliuy~

qwertyuiopasdfgh~

..........
$ cat inputfolder/abc.txt | tr -d "\r\n" > outputFolder/abc.txt
$ cat outputFolder/abc.txt 
abcdefgh~asdfghjkliuy~qwertyuiopasdfgh~..........

Or with sed:

$ sed -z "s/\n//g" inputfolder/abc.txt > outputFolder/abc.txt
