You did not upload your input file as I requested.

You did not tell us what operating system and version you're using as I requested.

You did not show us the output you are trying to get as I requested.

If your input file is encoded using ASCII and your locale has a collating order that matches ASCII unsigned character ordering, the simple command:
Code:
sort -o x.sorted x.raw

should do what I think you're trying to do. (And, on Mac OS X, it does.)

If the command:
Code:
sort -o x.sorted x.raw

or the command:
Code:
LC_ALL=C sort -t '|' -k1,1 -o x.sorted x.raw

doesn't produce the output:
Code:

(which is what I think you're trying to get) when the 1st two characters of the first and last fields on the 1st line are <space><backspace>, I don't know what else to suggest. Both of the above commands produce this output when using sort on Mac OS X and should produce the same output on any system with a sort utility that conforms to the standards.

Are you sure that you don't have an alias in place for sort that is adding options you don't want in this case? (What output do you get from the command: type sort?)
