Shell Programming and Scripting

Hello everyone!

I've been analyzing a foreign script and has come across the following line:

Code:

...
LC_COLLATE=1 sort -T "${tmp_dir}" "-t	" -k1,1 -k2,2 | \
...

And I can't understand how `LC_COLLATE=1' influences the behavior of the `sort' utility. I mean it is usually written `LC_COLLATE=C sort' in order to apply the default sort order. But how does `LC_COLLATE=1' affect the behavior of `sort' ? And what does `1' mean in this case? I've tried to search in the Internet and through manual pages but couldn't find anything explaining this.

Thanks in advance for your answers

I tried to get a clue too, but couldn't find anything helpful. Maybe it is a kind of typo. Did you try it with C instead of 1 and check if there is the same output on multiple runs?
Maybe it is not worth the time searching for an description. All man pages state that there is usually used some code for localization so 1 might stand for none, or default like C or... idk.

My first assumption would be that the script originally utilized a custome locale named "1" that was created specifically to affect this sort.

Thank you zaxxon and alister!

I've contacted the author, and he said that it had apparently been a typo. Many thanks for your help
