    پیش فرض mc and emelfm

    Dual pane Linux file managers: mc and emelfm

    I have been computing all my life without using a dual pane file manager until one day I decided that having one will greatly enhance my qualify of life. What I had in mind was something that will make my life easier in the copying or moving of files from 1 directory to another.

    By dual pane (or twin-pane) file manager, I mean a file manager that displays two directories side by side (one active, one passive). The term is confusing because often a dual pane file manager has a third pane that lets you enter commands to execute on the active directory.

    Staying true to my preference for Command Line Interface (CLI), I first tried Midnight Commander (mc). As advertised, mc is a file manager that is loaded with features. What I am looking for though is modest: a file manager with 2 directory panes that will satisfy my very basic day-to-day file management needs.


    I found myself customizing the look and feel of mc in the early adoption stage. The nostalgic white text on blue background had to go.

    You can run mc with the -b option to force black and white.
    $ mc -b

    If you don't want to go that far, you can customize the color used by editing the init file (~/.mc/ini).

    I inserted the following lines into the ~/.mc/ini file.

    [Colors]
    base_color=lightgray,green:normal=green,default:se lected=white,gray:marked=yellow,default:markselect =yellow,grayirectory=blue,default:executable=brightgreen,defau lt:link=cyan,defaultevice=brightmagenta,default:special=lightgray,defa ult:errors=red,default:reverse=green,default:gauge =green,default:input=white,graynormal=green,grayfocus=brightgreen,grayhotnormal=cyan,grayhotfocus=brightcyan,gray:menu=green,default:menuho t=cyan,default:menusel=green,gray:menuhotsel=cyan, default:helpnormal=cyan,default:editnormal=green,d efault:editbold=blue,default:editmarked=gray,blue: stalelink=red,default

    I also rearranged the panes so that they are placed horizontally (instead of vertically). You can interactively customize the placement using the mc Options menu (when you are already in mc). Alternatively, you can edit the ~/.mc/ini file, and make sure that the following horizontal_split line appears in the [Midnight-Commander] section:
    [Midnight-Commander]
    ....
    horizontal_split=1

    My mc window looked like this after the above customization.


    Another major annoyance is that if you run mc in a Gnome window, you cannot use the F10 key to quit mc. It turns out that F10 is normally the key to access the menu-bar in Gnome. To quit mc, you use your mouse to click the Quit soft-key.

    If it bothers you as much as it bothered me, you might want to disable the standard F10 menu-bar shortcut key for Gnome. To do that:
    $ gconftool-2 --set /apps/gnome-terminal/global/use_menu_accelerators --type bool false

    After giving it a good run for about 3 weeks, I gave up on mc. The determining factor was how mc handles the Tab key.

    Like other dual pane file managers, mc has a third pane that acts as the command line input window. However, the type of commands that will run in that window seems very limited. I tried commands such as date, pwd, ls, but they all showed no output. The most annoying feature to me is the Tab key. I am used to tapping the Tab key in a bash window for command completion. If you hit Tab while you are typing away in the mc's command line window, the effect is that mc switches the active focus to the other pane.

    I won't be surprised if someone tells me there is a way to customize the handling of the Tab key. But, at that point in time, I concluded that I will look for some other file manager that requires less adjustment and customization.

    I first became aware of emelfm because it is packaged with the Damn Small Linux (DSL) distribution. I decided to take a look at it because if it is included in DSL, it should be simple enough to satisfy my modest needs.

    emelfm is a GUI-based double pane file manager. It has a clean, simple, and intuitive UI. It does the basic file copying and moving. It also has some nice additional features such as the ability to set bookmarks and apply filters to filenames.

    One minor annoyance I find is when I try to copy a file in the active window to the same location. Essentially, what I want to do is copy and paste a file (to a new name) in the same directory in the active pane. I cannot use the Copy button to do it because it will only copy the file to the other pane. Instead, I need to enter the cp command explicitly in emelfm's command line window to do the copy.

    [P. Evans pointed out that emelfm has a Clone plugin that copies a file to the same directory. Click Configure and then Buttons. Add a button and select the Clone plugin.]

    Using the command line window in emelfm turns out to be a pleasant experience (as compared to mc). Hitting the Tab key will only switch the active pane if your mouse cursor is not in the command line window. If the cursor is in the command line window, hitting the Tab key does what I expect: command and filename completion. The commands that did not work in mc all worked well in emelfm (date, pwd, ls).

    I have been happily using emelfm since then. There are other GUI-based dual pane file managers out there: e.g., Krusader, Double Commander. I have not tried them. However, I do most file management on the CLI, and only occasionally use a GUI-based file manager to do file copying. As such, emelfm satisfies my requirement for a GUI-based file manager.
