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?
-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?
