This script will be included to my server.

Any suggestios? Bug fixes?

Code Sample

#!/bin/bash

# amusrpart.sh By: [email protected] (ICQ: 66768853 - MSN: [email protected] - IRC: Zucca@IRCnet)
# Full copyright owned by Zucca. First non-copyrighted relase will be version 0.1.xxx.;)
# Why? Because I'd like to finish this to... 'stable' version before anyone tries to use this. Any help is still very welcome.;)
# NOTE: This script is mainly designed for DSL LiveCD. I don't know how this would act if used with other distributions/installs.
# v 0.0.2b

# This simple script will mount all the partitions in all devices available on current computer for users if .mount.config is found from the root of partition.

for PARTITION in `ls /mnt/ | grep "[hs]d.[1-9]*"`
# Let's list all the hd* and sd* devices...
do

mount /mnt/$PARTITION 2> /dev/null

if [ -e /mnt/$PARTITION/.mount.conf ]
# Check if .mount.conf exists.

then
OWNER=`awk 'NR == 1' /mnt/$PARTITION/.mount.conf`
echo "$PARTITION owner: $OWNER"
MOUNTPOINT=`awk 'NR == 2' /mnt/$PARTITION/.mount.conf`
echo "Mount point: $MOUNTPOINT"
if [ -e $MOUNTPOINT ]
# If mount point specified in .mount.conf already exist then abort.
then
echo "Aborting mount: $MOUNTPOINT already exists."
umount /mnt/$PARTITION
else
umount /mnt/$PARTITION
# Next lines are commented because... Think what would happen if filetool.sh is executed.;)
# mkdir $MOUNTPOINT
# chmod 750 $MOUNTPOINT
# chown $OWNER $MOUNTPOINT
# chgrp staff $MOUNTPOINT

mount -o owner=$OWNER,mode=0750 /mnt/$PARTITION
# So instead mounting partition straight to $MOUNTPOINT we do regular mount and create a sym link.
ln -s /mnt/$PARTITION $MOUNTPOINT
fi
else
# Just simply unmount partition if .mount.conf cannot be found.
umount /mnt/$PARTITION
fi
echo ""
done

echo "User dedicated partitions mounted."

Thanks for all the tips I've received alredy from you guys.

Well now I'm back wiith this project. I have improves my script a bit but now I don't get what's wrong...

Here's the source:

Code Sample

#!/bin/bash

# amusrpart.sh By: [[email protected]][email protected][/EMAIL] (ICQ: 66768853 - MSN: [[email protected]][email protected][/EMAIL] - IRC: Zucca@IRCnet)
# Full copyright owned by Zucca. First non-copyrighted relase will be version 0.1.xxx.;)
# Why? Because I'd like to finish this to... 'stable' version before anyone tries to use this. Any help is still very welcome.;)
# NOTE: This script is mainly designed for DSL LiveCD. I don't know how this would act if used with other distributions/installs.
# v 0.0.5b

# This simple script will mount all the partitions in all devices available on current computer for users if .mount.config is found from the root of partition.

if [ ! -e /var/mount_confs ]
then
mkdir /var/mount_confs
fi

if [ -z $1 ]
then
echo 'USAGE: amusrpart.sh <mount|umount>'
exit
fi

TELLUSAGE="no"

for PARTITION in `ls /mnt/ | grep "[hs]d.[1-9]*"`
# Let's list all the hd* and sd* devices...
do

if [ $1 = "mount" ]
then

if [ -e /tmp/.amusrpart.mark ]
then
echo "Partitions already mounted."
echo "Or if you are sure that it is otherwise then delete /tmp/.amusrpart.mark"
exit
fi

mount /mnt/$PARTITION

if [ -f /mnt/$PARTITION/.mount.conf ]
# Check if .mount.conf exists.
then
OWNER=`awk 'NR == 1' /mnt/$PARTITION/.mount.conf`
echo "$PARTITION owner: $OWNER"
MOUNTPOINT=`awk 'NR == 2' /mnt/$PARTITION/.mount.conf`
echo "Mount point: $MOUNTPOINT"
if [ -e $MOUNTPOINT ]
# If mount point specified in .mount.conf already exist then abort.
then
echo "Aborting mount: $MOUNTPOINT already exists."
umount /mnt/$PARTITION
else
mv /mnt/$PARTITION/.mount.conf /var/mount_confs/mount.$PARTITION

# Next lines are commented because... Think what would happen if filetool.sh is executed.;)
# mkdir $MOUNTPOINT
# chmod 750 $MOUNTPOINT
# chown $OWNER $MOUNTPOINT
# chgrp staff $MOUNTPOINT

mount -o remount,owner=$OWNER,mode=0750 /mnt/$PARTITION

# So instead mounting partition straight to $MOUNTPOINT we do regular mount and create a sym link.
ln -s /mnt/$PARTITION $MOUNTPOINT
fi
echo ""
else
# Just simply unmount partition if .mount.conf cannot be found.
umount /mnt/$PARTITION
fi
elif [ $1 = "umount" ]
# move mount.conf back to partition and unmount.
if [ -f /var/mount_confs/mount.$PARTITION ]
then
mv /var/mount_confs/mount.$PARTITION /mnt/$PARTITION/.mount.conf
if [ -L $MOUNTPOINT ]
then
rm -fr $MOUNTPOINT
fi
umount /mnt/$PARTITION
fi
elif [ -n $1 ]
TELLUSAGE="yes"
fi

done

When I try to run it with mount option I get an error message:

Quote

./amusrpart.sh: line 83: syntax error near unexpected token `elif'
./amusrpart.sh: line 83: ` elif [ -n $1 ]'

There are the lines from 82 to 84:

Code Sample

fi
elif [ -n $1 ]
TELLUSAGE="yes"

Can you figure out what's wrong?
