I compiled busybox myself,and I put it in our embedded linux. But I have some questions.

Question 1:When I try to use some command such as gzip,it prints "gzip: applet not found".While I checked the menuconfig of busybox,I make sure that I've selected "gzip".

Question 2:I used to work with VIM,but busybox just provide VI.So I make a link VIM to VI,but when I typed vim and run it,it also show "vim: applet not found".

Anybody can help me with this problem that "applet not found"? Thank you very much.

PS:I'm confused with the "applet" of busybox,what it is? Like "applet" in java?

The answer to questions 1 and 2 is: you must set your PATH variable first or compile busybox with FEATURE_PREFER_APPLETS enabled. You can set the PATH variable with:

$ export PATH=/bin:/sbin:/usr/bin:/usr/sbin

A busybox applet is a small application that is usually found in the UNIX common utilities (defined in the POSIX standard). This applets are compiled into a single executable: busybox.
