6 | help | |
7 | Enable U-Boot's command-line functions. This provides a means | |
8 | to enter commands into U-Boot for a wide variety of purposes. It | |
9 | also allows scripts (containing commands) to be executed. | |
10 | Various commands and command categorys can be indivdually enabled. | |
11 | Depending on the number of commands enabled, this can add | |
12 | substantially to the size of U-Boot. | |

72a8cf8d SG |
17 | help |
18 | This option enables the "hush" shell (from Busybox) as command line | |
19 | interpreter, thus enabling powerful command line syntax like | |
20 | if...then...else...fi conditionals or `&&' and '||' | |
21 | constructs ("shell scripts"). | |
22 | ||
23 | If disabled, you get the old, much simpler behaviour with a somewhat | |
24 | smaller memory footprint. | |
