[help needed] make symlinks in dir to dir script for bashburn

Hi! i start using bashburn and i think is amazing! but the only thing is that to make the symlinks to /tmp/burn is tedious... i use tuxcmd and one file at the time i select from the right click menu "make symlink" for all the files i want... so i think to make an script to make symlinks from one directory to another and then when finish, delete those symlinks... BUT (BIG BUT ) i only want to make symlinks to /tmp/burn until it has dvd5 size (4,3gb?) adding symlinks in alfabethical order throught the original dir, because its no use if size is larger than DVD size i will need to delete those files... maybe later i can add the choose option between DVD sizes or specify a custom size

Here's what i have right now, need little help & comments i think this will be usefull to many

#!/bin/bash
#
echo ' -- Make symlinks script -- '
sleep 1
##### ORIGINAL DIRECTORY #####
IDIR=pwd
echo ' Original directory: ' $IDIR
echo ' -- press c to change directory, Enter to continue -- '
read DIR
while [ "$DIR" = c ]; do
    echo ' Enter new directory path: '
    read IDIR
    echo ' New directory: ' $IDIR
    echo ' -- press c to change, Enter to continue -- '
    read DIR
done
##### DESTINATION DIRECTORY #####
echo ' Destination directory: /tmp/burn '
echo ' -- press c to change directory, Enter to continue -- '
read DIR
while [ "$DIR" = c ]; do
    echo ' Enter new directory path: '
    read FDIR
    echo ' New directory: ' $FDIR
    echo ' -- press c to change, Enter to continue -- '
    read DIR
done
##### MAKE SYMLINKS #####
for x in $IDIR
do
    ln -s $IDIR/$x $FDIR/$x
    #HERE i think need to be the directory size limit check ($size or 4,5 gb limit), dont?
done
##### SHOW CREATED SYMLINKS #####
echo Symlinks created from $IDIR to $FDIR :
ls -l $FDIR
##### KEEP OR DELETE CREATED SYMLINKS #####
echo ' -- press k to keep symlinks in ' $FDIR ', Enter to delete created symlinks in ' $FDIR ' -- '
read
for x in $ODIR ; do
    rm $x
done
echo ' symlinks in $FDIR deleted '
sleep 3
##### SHOW DESTINATION DIRECTORY #####
echo ' content of $FDIR: '
ls -l $FDIR
echo ' Press a key to exit '
read
exit 0

Re: [help needed] make symlinks in dir to dir script for bashburn

Cool. I tried a bit, however -- it is not very much documented. Maybe you can use it:

#!/bin/bash
#
echo ' -- Make symlinks script -- '
sleep 1
##### ORIGINAL DIRECTORY #####
IDIR=$(pwd)
FDIR=/tmp/burn
ODIR=/tmp/other
# MAXSIZE in kbytes
MAXSIZE=$(( 120 * 1024 ))
echo $MAXSIZE
echo ' Original directory: ' $IDIR
echo ' -- press c to change directory, Enter to continue -- '
read DIR
while [ "$DIR" = c ]; do
    echo ' Enter new directory path: '
    read IDIR
    echo ' New directory: ' $IDIR
    echo ' -- press c to change, Enter to continue -- '
    read DIR
done
##### DESTINATION DIRECTORY #####
echo ' Destination directory: /tmp/burn '
echo ' -- press c to change directory, Enter to continue -- '
read DIR
while [ "$DIR" = c ]; do
    echo ' Enter new directory path: '
    read FDIR
    echo ' New directory: ' $FDIR
    echo ' -- press c to change, Enter to continue -- '
    read DIR
done
##### MAKE SYMLINKS #####
for x in $(ls -l $IDIR|grep ^d|cut -d " " -f 9)
do
    SIZE=$(du -k --max-depth=0 $IDIR/$x | cut -f 1)
    if [ $SIZE -lt $MAXSIZE ]
    then
    echo "Creating link for dir: $x  size: $SIZE"    
        ln -s $IDIR/$x $FDIR/$x
    else
    echo "Not creating link for dir: $x  size: $SIZE"
    fi
    #HERE i think need to be the directory size limit check ($size or 4,5 gb limit), dont?
done
##### SHOW CREATED SYMLINKS #####
echo Symlinks created from $IDIR to $FDIR :
ls -l $FDIR
##### KEEP OR DELETE CREATED SYMLINKS #####
echo ' -- press k to keep symlinks in ' $FDIR ', Enter to delete created symlinks in ' $FDIR ' -- '
read
for x in $ODIR ; do
    rm $x
done
echo ' symlinks in $FDIR deleted '
sleep 3
##### SHOW DESTINATION DIRECTORY #####
echo ' content of $FDIR: '
ls -l $FDIR
echo ' Press a key to exit '
read
exit 0

Re: [help needed] make symlinks in dir to dir script for bashburn

WOW THANKS! great improvement, i see now if i can make it to work like i want!

i dont understand really this part:

# MAXSIZE in kbytes
MAXSIZE=$(( 120 * 1024 ))
echo $MAXSIZE

because this give me 122880 but dont understand really, whit this you mean dvd size? or i need to modify it to that size?

and this:

##### MAKE SYMLINKS #####
for x in $(ls -l $IDIR|grep ^d|cut -d " " -f 9)
do

because if i run that in a directory the output is like this:

[aleyscha@aleyscha ~]$ ls -l /sda6/Movies |grep ^d|cut -d " " -f 9




[aleyscha@aleyscha ~]$

and i have a lot of movies in that dir (with spaces in each filename)

Thanks in advise! this is really improving

Re: [help needed] make symlinks in dir to dir script for bashburn

I discover that if i remove the "-l" parameter in:

##### MAKE SYMLINKS #####
for x in $(ls -l $IDIR|grep ^d|cut -d " " -f 9)
do

instead of garbage i get only those filenames with no spaces, this is more like we need i think, but dont shows those filenames with spaces i get:

[aleyscha@aleyscha ~]$ ls /sda6/Movies | cut -d " " -f 9
./
../

2010.avi
300.avi


Akira.avi
Alien.avi
Animatrix.avi
Animatrix.srt


Avalon.avi
Avalon.sub

and there are files in between tha blank lines, files with spaces in his filename... and i think that the "./" and "../" filenames will be a problem, aren't? because they enter in the x variable for create a symlink to it, or they aren't?

we are getting closer

Re: [help needed] make symlinks in dir to dir script for bashburn

Wow, didn't thought about those things. My assumption was each DVD would have top level directories like so:

Series
Movies
Anything_else

The

 
ls -l /sda6/Movies |grep ^d|cut -d " " -f 9

does the following: It lists the contents of the Movies dir and greps for lines beginning with d like
drwx-r-xr-x ... Series
drwx-r-xr-x ... Movies
drwx-r-xr-x ... Anything_else

The cut cuts off the last part (separted by spaces -- this will separte file names with spaces.
If you have file on the toplevel this wont work.

Another command would be more appropriate:

find /sda6Movies --maxdepth=0

I think, this will give you the file list. When you do the ln you may need to add '"', like:
ln -s "$IDIR/$x" "$ODIR/$x"

The size basically calculates the total size of files in kbytes, you want on your medium. I guess for DVD it would be something like
MAX_SIZE=$(( 4 * 1024 * 1024 ))

Or put the real size in Kbytes (i think bash can't do floats like: 4.5 * 1024 * 1024)

Have fun!
