I have a file temp.txt, that I want to sort with the sort command in bash.
I want the sorted results to replace the original file.
This doesn’t work for example (I get an empty file):
sortx temp.txt > temp.txt Can this be done in one line without resorting to copying to temporary files?
EDIT: The -o option is very cool for sort. I used sort in my question as an example. I run into the same problem with other commands:
uniq temp.txt > temp.txt. Is there a better general solution?
