If I had to guess, you are expecting sed to modify the file when what sed does is read the file and write the changes its made to standard output, not to the original file itself. If that guess is correct, the following should work (back up your file first, just in case, or work with a copy of it):
Code:
printf '%s\n' '1,$s/ $//' w q | ed -s file

If that didn't work, are you sure that those are spaces and not some other blank character? You can verify using hd/hexdump/od. If you don't understand the output of those commands, simply paste them here. Don't forget to use code tags for code and data (to preserve formatting).

When I created a .txt file whit words and spaces and then used
Code:
cat /root/input.txt | sed 's/ *$//g' > output.txt

it removed all spaces at the end of each line
but when I apply this to my file its not working. when I used the command
Code:
 cat /root/myfile.txt | sed 's/ *$/A/g' > myfile1.txt

I got this:
word1[space]
A
word2[space]
A
...and so on
but it supposed to be:
word1A
word2A...
I suppose there's something wrong with this file. I merged 2 txt files and created one I want to remove spaces there now
there are no error messages, I always get an output file, but with no result
I didnt get it how can I verify whether there are some other blank characters
cant explain you better, sorry,I am a noob with poor eng.

I changed encoding of the whole document to ISO 8859-15 and performed
Code:
 cat input.txt | sed 's/ *$//g' > output.txt

and it finally worked
Thank You again for your responses
