Your are opening the temp file again and again inside the `cut`. I haven't
duplicated your script, but you will always start from the first record of
"temp".

As you probably want the cut to work only on the current line being read,
you might like to try instead :
#!/bin/bash
clear
for SOMEVAR in `cat temp`
do
USERID=`echo $SOMEVAR | cut -f5 -d/`
usermod -d $SOMEVAR -m $USERID
done
exit 0
or
#!/bin/bash
clear
for SOMEVAR in `cat temp`
do
usermod -d $SOMEVAR -m `basename $SOMEVAR`
done
exit 0
The following script may execute faster though, as fewer programs are started
up:
# !/bin/bash
clear
IFS='/'
cat temp | while read dp1 dp2 dp3 dp4 userid
do
usermod -d /$dp2/$dp3/$dp4 -m $userid
done
exit 0
