looping in hexadecimal with bash
hello every one this is my first post ... well i'm new to linux ....
i've been enjoying shell scripting tutorials and i'm new to writting scripts
i want to write a script that creates a directory tree named in hexadecimal but i'm stuck at the hexadecimal part ... here is my code (incase i was dealing with intergers ...using bash)
max=39
for((i=1;i<=max;i++))
do
mkdir $i
cd$i
done
i have tried using "typeset i16 i" but this gives me an error in bash but it works with ksh yet it names my directories with the "16#" part in ksh ...
any suggestions on how i can improve my code ... and can i make it work in bash and ksh esp bash ... i've seen posts like mine on the topic of hexadecimals but, ksh was the remedy.

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
