CentOS - May 2014 - bash script reading directory with while and do

hi everyone,

I'm searching to do a functionally bash script for copy many file inside
in a directory
the scenario is:

root path= /var/www/clients/
inside of this there are many subdirectories with this name: client1 to
x (depends of the customer)
it happens that a customer not renew the contract and I would stopping
to do a backup directory for him.

this operation should be versatile and very easy
so, I don't understand the error in this script. look below:

!/bin/bash

while read line;
do
        read NR PATH NAME<<<$(IFS=" "; echo $line)

        cd /var/www/clients/
        cp -R $PATH /backup/temp/www/
        cd /backup/temp/www/

        tar cfz `date +%F`_$NAME.tar.gz web$NR/
        mv *.tar.gz /backup/www/test/
        rm -rf /backup/temp/www/*

done < sites.txt

anyone can help me, please?
thanks in advance

regards

Hi
you are overwriting the PATH env variable.
change PATH to CLIPATH and all will work

A few things:

1. A shebang is two chars, "#!", not just an exclamation point.
    (possibly just a typo / copy error)


2. $PATH is special, use something else (e.g. $path).


3. Your `tar` stanza is wrong (if it's not obvious to you why that is,
    now is a good time to make a habit of using long options
    (e.g. `--gzip`) whenever possible).


4. Always quote variables that could possibly have whitespace in them
    ($NAME in this case).



What is it you're trying to accomplish with the IFS and echo?
Why not just

      while read nr path name;
      do
          : stuff goes here
      done
