Ok. Honestly, it doesn't feel quite right to me. I haven't played with U-Boot's shell too much but is there no way to assign variables from command outputs? For example, can we do something like `foo=$(cat a.txt)`? If that is possible, maybe add some new subcommands to "sf" that return this information? -- Regards, Pratyush Yadav Texas Instruments Inc.
