- PROGRAM:
- SORT - Sorts a file on a specified key
- USAGE:
- SORT [<fid] [-R] [-U] [-Cn] [-Ln] [-H] [>fid]
- FUNCTION:
- This program does an internal sort of up to 512 entries.
- Input and output are the standard redirectable input and
- output. Options include:
-
- -R Reverse order sort.
- -U Convert to upper case before comparing.
- -Cn First column to begin compare. 1 is default.
- It is ok to specify a position longer than some
- lines. Lines shorter will compare as equal.
- -Ln Length of field to compare. Full line length is default.
- -H Display the available options.
-
- EXAMPLE:
- SORT <A -C10 -L10 -R
- WORDS <FILE |SORT |UNIQUE -N |SORT {Gives word list by frequency.)
- COMMENTS:
- This is an internal sort which uses the available space in memory.
- If the input file is too big, an out of space error will be given.
-
- The sort is "stable" and it is possible to sort on a less
- significant field first and a more significant field second.
- Cascading sorts in this way can give sorts on complicated keys
- with some descending and some ascending.
