@ -46,6 +46,17 @@ Urchin depends on the following programs.
|
|||
All of the above programs are usually included on base BSD installations.
|
||||
On GNU systems it should be sufficient to install the busybox package.
|
||||
|
||||
Urchin uses sort to format its output. GNU sort (as of GNU coreutils version
|
||||
8.24) lacks the ability to sort in lexicographic order, and this feature is
|
||||
necessary for the output to look right. If your version of sort lacks this
|
||||
feature, Urchin will try to use one of the following tools for sorting.
|
||||
|
||||
If no acceptable sorting program is available, Urchin will print a warning
|
||||
and use the incomplete sort that is installed on your system. This is not a
|
||||
big deal; if your test files all start with alphanumeric letters, the output
|
||||
should look fine.
|
||||
|
||||
|
||||
## Install
|
||||
Urchin is contained in a single file, so you can install it by copying it to a
|
||||
directory in your `PATH`. For example, you can run the following as root.
