Help me with awk and grep script

Code:
#!/bin/sh
PRINTF=/usr/bin/printf

$PRINTF "Enter a UserID\n"
read USERID

for USERID in `cat passwd | awk -F : '{print $1}'`
do
    USERHOME=`grep ^$/qianxin/ passwd | awk -F : '{print $6}'`
    USERSHELL=`grep ^$/qianxin/ passwd | awk -F : '{print $7}'`

$PRINTF "$USERID\n"
$PRINTF "$USERHOME\n"
$PRINTF "$USERSHELL\n"

done

Hi all, I got execution problem with this script, can someone please help me fix it?

In this script, first promote the user enter a valid ID, then if the ID is in the first field of a passwd file, system will print out the sixth and seventh filed. The type of a passwd file is in this way:
root:89898:93434:root...:dfdfd:ererer:ferer:

thx a lot!

NAME
bzexe - compress executable files in place SYNOPSIS
bzexe [ name ... ] DESCRIPTION
The bzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``bzexe /bin/cat'' it will create the following two files: -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~ /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that /bin/cat works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
bzip2(1), znew(1), zmore(1), zcmp(1), zforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep). BUGS
bzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. BZEXE(1)
