Check this post out. How to remove all white spaces from a given text file

You want the tr command. You can do something like cat file.txt | tr -d " \t\n\r"

And if you wanna do it for all the files in the directory, you could use a find command. Something like find . | xargs tr -d " \t\n\r

EDIT - Just noticed you wanna keep the line breaks. You can omit the newlines from the tr command

    UUOC: `cat file.txt | tr -d " \t\n\r"` -> `tr -d " \t\n\r" < file.txt`. Consider using the POSIX character class `[:blank:]`. – Ed Morton Mar 29 '17 at 14:09

    Good point Ed. It's always better to be explicit, makes things easier to read. – Steve Mar 30 '17 at 17:48

Using sed

 $sed -e "s/ //g" file1.txt

You can add -i to change the file in place.
