Shell Programming and Scripting

Hi ,first of wall im new to Shell Scripting .
So far i`ve prepared a simple shell script which can execute few of commands on a busybox (Linux Embed System) .

Code:

#!/bin/sh
CMD1="cd /tmp/hd/"
CMD2="ls -l > show"
$CMD1
$CMD2
done

so far i think this should work ,but it would not.
So if anybody can write something similar to that ,because what i need is to view list of files and file size on that dir. than output it on a txt file .
Next step is upload that file using ftp but that is simple i did it before .
the upload command is

Code:

ftpput -u user -p pass 192.168.1.1 / filename

Thanks and best on advance .

Code:

ls -l | awk '/^-/ {printf "SIZE=%-6d FILES=%-15s\n",$5,$9}' > my_file.txt

yes, the redirect won't work in quotes like that,

eval $CMD

Hi ,than eagle that form print`s a great sorted list with only 2 dettails ,but i did a simpler one which output all "ls -l" by typing it in `ls -l /dir/ > /dir/my_file/`

Best on advance and thanks for help .

I have another short question ,and i think it is out of this thread .

Hos is possible to run another script from a script .

i used CMD=". /path/script.sh"
$CMD

but i didn`t work .

First of all be sure that you have the execution permission to run the script.
when you write a script you can add "-x" trace option to see how your script runs, will show you wrong parts too,

Code:

#!/usr/bin/bash -x

you can trigger a script from inside another script. Lets assume you want to ftp "gz" and "tar" files when total size of all these files exceeds 500 MB

Code:

cat script1.sh
SUM=`find . \( -name "*.tar" -o -name "*.gz" \) -exec ls -l {} \; | nawk '{a+=$5}END{printf"%15d\n",a}'`

if [ $SUM -ge 50000000 ]; then
./my_script_path/script2.sh
else
echo "compressed files are OK"
fi

Code:

cat script2.sh
cd /my_directory
....PUT YOUR FTP SCRIPT HERE....
.....

i hope this gives you an idea about what you looking for
