+#  dk-sort — Sort text line by line


+## Description
+
+The program sorts input text from the specified files (or from standard input if no file is specified) line by line.
+There are some differences to traditional sort programs:
+
+
+Different input encodings

+The program can handle different input encodings (i.e. ASCII, UTF-8
+for files produced on Linux/Unix systems and UTF-16 for files produced
+on Windows systems).

+You can use the -i option to specify an expected input encoding.
+This choice is overwritten if a BOM (byte order marker) is found at start
+of input data.
 
+
+Options for numeric sorting

+You can use the options -n, -u, or -f to sort input
+by leading signed integer, unsigned integer, or floating point numbers
+at start of lines.
+

+## Examples
+
+### Find newest files (last modified)
+
+To find the files last modified:
+
+~~~
+dk-ls -r -tf -pmtn | dk-sort
+~~~
+
+Program|Option|Purpose
+-------|------|-------
+dk-ls||List files.
+|-r|Recursive listing including all subdirectories.
+|-tf|Restrict output to files (non-directory items).
+|-pmtn|Set print order to:
m Modification time
t File type
n File name
+dk-sort||Sort text line by line alphabetically.
+
+### Find largest files
+
+To find the largest files in a directory:
+
+~~~
+dk-ls -r -tf -pstn | dk-sort -u
+~~~
+
+Program|Option|Purpose
+-------|------|-------
+dk-ls||List files.
+|-r|Recursive listing including all subdirectories.
+|-tf|Restrict output to files (non-directory items).
+|-pstn|Set print order to:
s File size (number of bytes)
t File type
n File name
+dk-sort||Sort text line by line.
+|-u|Sort by unsigned number at start of line.
+
+### Group files by file type suffix, sort by size
+
+To list all files, group by file type suffix and sort each group by size:
+
+~~~
+dk-ls -tf -psn | dk-sort -u -t -s 1
+~~~
+
+Program|Option|Purpose
+-------|------|-------
+dk-ls||List files.
+|-tf|Restrict output to files (non-directory items).
+|-psn|Set print order to:
s File size (number of bytes)
n File name
+dk-sort||Sort text line by line.
+|-u|Sort by unsigned number at start of line.
+|-t|Sort by file type suffix.
+|-s 1|To find the file type suffix, skip the first text word in each line (the size).
+
+### Find largest subdirectory
+
+To find the largest subdirectory:
+
+~~~
+dk-ls -r -td -pstn | dk-sort -u
+~~~
+
+Program|Option|Purpose
+-------|------|-------
+dk-ls||List files.
+|-r|Recursive listing including all subdirectories.
+|-td|Restrict output to directories.
+|-pstn|Set print order to:
s File size (number of bytes)
t File type
n File name
+dk-sort||Sort text line by line.
+|-u|Sort by unsigned number at start of line.
+
+### Group files by file type suffix, sort by modification time
+
+To list all files, group by file type suffix and sort each group by modification timestamp:
+
+~~~
+dk-ls -tf -pmn | dk-sort -t -s 2
+~~~
+
+Program|Option|Purpose
+-------|------|-------
+dk-ls||List files.
+|-tf|Restrict output to files (non-directory items).
+|-pmn|Set print order to:
m Modification timestamp
n File name
+dk-sort||Sort text line by line.
+|-t|Sort by file type suffix.
+|-s 2|To find the file type suffix, skip the first two text words in each line (modification date and modification timestamp).
+
