What's wrong on this script?
I get this error on these lines when i run this script:"[: `)' expected,found 20
What am i doing wrong?

Code:
for i in /home;do

file2=`ls -s $i`

if [ \( $file2 -ge $2 \) -a \( $file2 -le $3 \) ];then

ls - s $i

fi
done

If you try to explain what exactly you're trying to achieve, it would be definitely easier ...

I want to print on the screen the names of files in the HOME of the user that the size is greater than or equal the second argument and less than or equal to the third argument. Eventually it will be printed and the total size of these files.

Which OS are you using? You can achieve most of that with a single command.

This is the content of my home directory:

Code:

The following command will display the files between 10 and 1000k:

Code:
zsh-4.3.14[sysadmin]% find . -maxdepth 1 -type f  -size +10k -a ! -size +1000k -printf '%f -> %kk\n' 
.bash_history -> 8k
.histfile -> 290k
.zcompdump -> 18k

Note that most of the options used in the above find command are not standard (i.e. they are not available on most Unix systems),
but the important one -size is usually available (with limited argument modifiers).

P.S. I'm not sure why 8k is in the output Smilie

P.P.S. Perhaps this should be more appropriate example:

Code:
zsh-4.3.14[sysadmin]% find . -maxdepth 1 -type f  -size +10k -a ! -size +1024k  -exec ls -lh {} +
-rwxr-xr-x 1 Administrators None  16K Dec 19 20:14 ./.bash_history
-rwxr-xr-x 1 Administrators None 579K Dec 19 21:53 ./.histfile
-rw-r--r-- 1 sysadmin       None  33K Dec  7 23:13 ./.zcompdump

Code:
              The size does not count indirect blocks, but it does count blocks in sparse files that are not actually
              allocated.   Bear  in mind that the `%k' and `%b' format specifiers of -printf handle sparse files dif-
              ferently.  The `b' suffix always denotes 512-byte blocks and never 1 Kilobyte blocks, which is  differ-
              ent to the behaviour of -ls.
