Thread: wl700gE shell type

    wl700gE shell type

    what is the difference between #!/bin/sh and #!/bin/ash

    the question is because of wl700gE uses #!/bin/ash and if I try to run a script:

    # cat /shares/MYVOLUME1/MYSHARE1/test.sh
    #!/bin/ash
    mkdir /tmp/root
    I get error:

    # /shares/MYVOLUME1/MYSHARE1/ipkg.sh
    /bin/ash: error while loading shared libraries: /bin/ash: symbol vprintf, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

    If I run :

    # cat /shares/MYVOLUME1/MYSHARE1/test.sh
    #!/bin/sh
    mkdir /tmp/root
    I get:

    # /shares/MYVOLUME1/MYSHARE1/test.sh
    : cannot open
    also I'm curious why does it work at all, if /tmp/passwd has /bin/sh:
    # cat /etc/passwd
    root::0:0:root:/:/bin/sh
    guest::35000:42000:guest:/:/bin/sh
    but wl700gE uses /bin/ash?

    should I configure busybox to enable shell script execution?

    It does execute scripts.. If you look there is a symlink to 'sh' which links back to busybox (as does ash if I recall) If you don't have it then you'll have to recompile busybox with sh enabled. ash if I remember correctly is similar to sh and bash, but has a smaller footprint, and is incorporated into busybox.

    It would appear that the ash shell is part of busybox.

    It is supposed to be compatible with /bin/sh
