You cannot redirect stuff into a file due to padmin restrictions but you can use

vi

if you want to write a script or something. By the way, $HOME is in PATH. Take a look:

$ pwd
/home/padmin
$ echo "echo hello" >bah 
rksh: bah: 0403-019 The operation is not allowed in a restricted shell.
$ vi bah
$ chmod 755 bah
$ /home/padmin/bah
rksh: /home/padmin/bah: 0403-019 The operation is not allowed in a restricted shell.
$ ./bah
rksh: ./bah: 0403-019 The operation is not allowed in a restricted shell.
$ bah
hello
