[improve] command prompt

[sc0ttj]

The "shell prompt" mode can only run commands in the following syntax:

$cmd $selection

where:

• $cmd is the command chosen from the list, or typed out
• $selection is the file(s) chosen in file manager mode

Need to work out how to insert $selection into any place in a command string, so users can write stuff like the following and hit ENTER:

mv {} some/new/path/{}
cp {} some/new/path/

where:

• {} is each file listed in $selection

Maybe use something like this:

# echo -e "1a
2b
3c" | xargs -P $(nproc --ignore=1) -d'\n' -I{} -n1 -r echo "FOO {} BAR"

FOO 1a BAR
FOO 2b BAR
FOO 3c BAR

xargs options explained:

-P $(nproc --ignore=1) - the -P enables multiple threads, nproc reports how many are available
-d'\n' - use newline char as delimeter
-I{} - replace {} with the incoming line, implies -L1 (max lines one, the default)
-n1 - max args 1 (everything on the incoming line is interpolated into {})
-r - dont run following command if the incoming line is empty
