+
+```
+sort [opts] [file]
+ opts:
+ -r reverse output
+ -b ignore leading blanks
+
+ -n sort by numeric
+ -h sort by human numeric
+ -V sort by version
+
+ -k<N> sort by Nth key
+ -t<S> field separator
+```
+
+## Examples
+```sh
+# Sort by directory sizes.
+du -sh * | sort -h
+```
+
+```sh
+# Sort numeric by second key.
+# The default key separator is non-blank to blank transition.
+echo 'a 4
+d 10
+c 21' | sort -k2 -n
+
+# Sort numeric by second key, split at comma.
+echo 'a,4
+d,10
+c,21' | sort -k2 -n -t,
+```
+> Use `--debug` to annotate part of the line used to sort and hence debug the key usage.
