Variable loses value outside loop

Hi,

I am looking for a global variable found_flag to be set a value that can be accessed outside the loop anywhere in the bash shell script.

Code:

 more test.sh
 found_flag=0
 searchdir=/web/bea_apps/applications
  
 find . -type f \! -name tasty.tar | $AWK -F/ '{print $NF}' | while IFS= read -r entry; do
  
 found_flag=0
 find $searchdir -type f -name $entry | grep -v LOGS | while IFS= read -r second_entry; do
  
 mv $second_entry $second_entry.$NOW.bkp
 cp -R $entry `dirname $second_entry`/
 found_flag=1
 echo "Displaying the value of found_flag:$found_flag"
  
 done
  
 echo "Displaying the value of found_flag outside while loop:$found_flag"
  
 done

Output: bash -x test.sh

Code:

 
 + find . -type f '!' -name client.tar
 + /usr/xpg4/bin/awk -F/ '{print $NF}'
 + IFS=
 + read -r entry
 + found_flag=0
 + find /web/bea_apps/applications -type f -name sd.ear
 + grep -v CURRENT
 + IFS=
 + read -r second_entry
 + mv /web/bea_apps/applications/sd.ear /web/bea_apps/applications/sd.ear.10032017.bkp
 ++ dirname /web/bea_apps/applications/sd.ear
 + cp -R sd.ear /web/bea_apps/applications/
  
 + found_flag=1
 + echo 'Displaying the value of found_flag:1'
 Displaying the value of found_flag:1
 + IFS=
 + read -r second_entry
 + echo 'Displaying the value of found_flag outside while loop:0'
 Displaying the value of found_flag outside while loop:0

In the RED BOLD output above I am expecting the found_flag to have the value=1 instead of zero.

Can you please suggest a quick way how I can set the value globally so it reflects outside the loop as well ?

Using sub-shells would be my last priority.

Hi Guys, i have learned today that when you ftp a file with full write permissions (777) to another destination it loses the w options. so a file that was once -rwxrwxrwx(before FTP) is now -rw-r--r-- (after FTP). why does this happen? and is it configurable? Regards,

verifier

verifier(1M)                                                Application Server Utility                                                verifier(1M)

NAME

       verifier - validates the J2EE Deployment Descriptors against application server DTDs

SYNOPSIS

       verifier [-v] [-d destination_directory] [-r [a|w|f]] jar_filename

       Use the verifier utility to validate the J2EE deployment descriptors and the Sun ONE Application Server specific deployment descriptors. If
       the application is not J2EE compliant, an error message is printed.

       When you run the verifier utility, two results files are created in XML and TXT format. The location where the files  are  created  can  be
       configured  using  the  -d  option.  The directory specified as the destination directory for result files should exist. If no directory is
       specified, the result files are created in the current directory. Result files are named as jar_filename_verified.xml and jar_filename_ver-
       ified.txt

       The  XML  file  has  various sections that are dynamically generated depending on what kind of application or module is being verified. The
       root tag is static-verification which may contain the tags application, ejb, web, appclient, connector, other, error and failure-count. The
       tags are self explanatory and are present depending on the type of module being verified. For example, an EAR file containing a web and EJB
       module will contain the tags application, ejb, web, other, and failure-count.

       If the verifier ran successfully, a result code of 0 is returned. A non-zero error code is returned if the verifier failed to run.

OPTIONS

       -v                       verbose debugging is turned on.

       -d                      identifies where the result files get placed.

       -r                      identifies the reporting level defined as one of the following:

                                 o  a sets output reporting level to display all results (default)

                                 o  w sets output reporting level to display warning and failure results

                                 o  f sets output reporting level to display only failure results

       jar_filename            name of the ear/war/jar file to perform static verification on. The results of verification are placed in two files
                               jar_filename_verified.xml and jar_filename_verified.txt in the destination directory.

       Example 1: Using verifier in the Verbose Mode

       example% verifier -v -d /verifier-results -rf sample.ear

       Where  -v  runs  the  verifier in verbose mode, -d specifies the destination directory, and -rf displays only the failures. The results are
       stored in /verifier-results/sample.ear_verified.xml and /verifier-results/sample.ear_verified.txt.
