Full Discussion: Differences in printed commands after execution with same code
Top Forums Shell Programming and Scripting Differences in printed commands after execution with same code Post 302573992 by mjf on Wednesday 16th of November 2011 08:22:46 AM
Old 11-16-2011
I'm trying to find the reason for the different behavior when the commands and arguments are printed using set -x when the same function is executed. In the Undesired Results, you can see that when $status_cnt = 2, the end result is the same (i.e. the loop continues) as in the Desired Results but when when $status_cnt = 1, the loop prematurely exits in the Undesired Results.
The purpose of the translate function tr -d [0-9] is to delete numerics before assigning to temp variable but why do I see "+ + tr -d 2" in the Undesired Results and why is the print order different when executing the same function?


Here is the function:

Code:
 
check_report_completion()
#ARG1 = jobid array
{
set -x
jobid=$1
status_cnt=9999
until [ $status_cnt -eq 0 ]
do
sleep 15 
sqlplus -s $AS_CONNECT_STRING<<EOF |read status_cnt
whenever sqlerror exit sql.sqlcode; 
SET FEEDBACK OFF;
SET PAGESIZE 0;
select count(*)
from rw_server_queue where job_id in ($jobid)
and status_code in (1,2,3,10);
EOF
temp1=`echo $status_cnt|tr -d [0-9]` 
temp2=${temp1:-"numer"}
if [ $temp2 = "numer" ] 
then
:
else
status_cnt=9999
break
fi
done
echo $status_cnt
}

Desired Results Execution:

Code:
 
+ + check_report_completion 0,14193,14194
+ jobid=0,14193,14194
+ status_cnt=9999
+ [ 9999 -eq 0 ]
+ sleep 15
+ read status_cnt
+ sqlplus -s /@compasp
+ 0<<
whenever sqlerror exit sql.sqlcode; 
SET FEEDBACK OFF;
SET PAGESIZE 0;
select count(*)
from rw_server_queue where job_id in (0,14193,14194)
and status_code in (1,2,3,10);
+ + echo 2
+ tr -d [0-9]
temp1=
+ temp2=numer
+ [ numer = numer ]
+ :
+ [ 2 -eq 0 ]
+ sleep 15
+ read status_cnt
+ sqlplus -s /@compasp
+ 0<<
whenever sqlerror exit sql.sqlcode; 
SET FEEDBACK OFF;
SET PAGESIZE 0;
select count(*)
from rw_server_queue where job_id in (0,14193,14194)
and status_code in (1,2,3,10);
+ + echo 1
+ tr -d [0-9]
temp1=
+ temp2=numer
+ [ numer = numer ]
+ :
+ [ 1 -eq 0 ]
+ sleep 15
+ read status_cnt

Undesired Results Execution:

Code:
 
+ + check_report_completion 0,28030,28031
+ jobid=0,28030,28031
+ status_cnt=9999
+ [ 9999 -eq 0 ]
+ sleep 15
+ read status_cnt
+ sqlplus -s /@compasp
+ 0<<
whenever sqlerror exit sql.sqlcode; 
SET FEEDBACK OFF;
SET PAGESIZE 0;
select count(*)
from rw_server_queue where job_id in (0,28030,28031)
and status_code in (1,2,3,10);
+ + tr -d 2
+ echo 2
temp1=
+ temp2=numer
+ [ numer = numer ]
+ :
+ [ 2 -eq 0 ]
+ sleep 15
+ read status_cnt
+ sqlplus -s /@compasp
+ 0<<
whenever sqlerror exit sql.sqlcode; 
SET FEEDBACK OFF;
SET PAGESIZE 0;
select count(*)
from rw_server_queue where job_id in (0,28030,28031)
and status_code in (1,2,3,10);
+ + echo 1
+ tr -d 2
temp1=1
+ temp2=1
+ [ 1 = numer ]
+ status_cnt=9999
+ break
+ echo 9999

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
