I've found another way to list my dirs and wants to check each dir with the du -khs command.
I have all the directories in a file and wants to read the file and the perform the task for each of the dirs in it.

the file consists of rows with dir names followed by /

can I cat the file in my script and the perform a foreach loop on them? any suggestions?
The output should be one logfile for each of the dirs

Since you have not specified sample input file; I’m going to assume that your file is as follows:

input.txt

Code:

/tmp
/home/vivek
/home/foo
/home/bar
/etc

Shell script

Code:

#!/bin/bash
INPUT="input.txt"
LOG="/tmp/log.txt"
>$LOG #init log file
for f in $(cat $INPUT); do du -ksh $f >>$LOG; done
echo "See log file $LOG"

Let me know if you need any further help..

I've tried some different syntaxes and managed to perform the task like this:

Code:

for i in $(ls -p); do du -khs echo $i; echo $i; done > temp1
cat temp1 | grep ^[0-9] | grep /$ > temp2

tihis little loop gives an output like this:

Code:

5.6M    bin/
6.7M    boot/
168K    dev/
60M     etc/
597M    home/
8.0K    initrd/
89M     lib/
16K     lost+found/
16K     media/
8.0K    misc/
8.0K    mnt/
8.0K    opt/
899M    proc/
143M    root/
16M     sbin/
0       selinux/
8.0K    srv/
0       sys/
576K    tmp/
2.4G    usr/
138M    var/

but it also gives me the error message:

Code:

du: cannot access `echo': No such file or directory

it might not be a problem since the output is good, but it looks bad...
the next problem is that i want to specify a directory to go further down in and perform the same task, lets say i want to check the content of the home/ directories, how can i do this?
My home directory catalogue structure is like this..

Code:

home/
         group1/
                    user/
                    user1/
                    user2/
         group2/
                    user/
                    user1/
                    user2/

I want the logfile to tell me how much each group dir contains, number of directories and size..
can you give me som hints?

Use for command to get list of dirs:

Code:

LIST= $(find /home -type d)

And run command

Code:

for d in $LIST; do du -ksh $d>>/tmp/list.txt; done

View file

Code:

less /tmp/list.txt

Hope this helps!

Thanks a lot!
I will mix a bit with it and see if i can get it to work smoothly, it seams realy nice!

I will write again when it is finnished or when I get stuck again!

i just cant get it to work the way i want..

this is what it looks like at the moment

Code:

home/
         group1
                  backup
                             users///
         group2
                   backup
                             users///

I realized that the backup catalogue was forced to be there (it is consistent), the big issue is that I need to check the size of the user-catalogues and this is tricky since I want the script to be dynamic and nog bound to the names of the groups.

I happy that I went to the hairdresser the other day, otherwise I would be tearing my hair of!
