Shell Programming and Scripting

Hi,

When I compare currentfiledate to reportfiledate I get a "-bash: [: 20090220080101: integer expression expected " error message.

currentfiledate=20090220080101
reportfiledate=20090219231245

if [ $currentfiledate -gt $reportfiledate ] ; then
echo -ne "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! \n"
echo -ne "!! Running the load utility !! \n"
fi

Our computer has a 64 bit processor, so I know it can handle the value in the variable.

What am I missing ?

Thank you.

works fine under Solaris' "bash".
Does not work correctly under 'sh'.

Make sure you specify a desired shell interpreter in the first line of your script:

Code:

#!/bin/bash
currentfiledate=20090220080101
reportfiledate=20090219231245

if [ $currentfiledate -gt $reportfiledate ] ; then
   echo -ne "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! \n"
   echo -ne "!! Running the load utility !! \n"
fi

Hi,

I had the statement in the program. Sorry, I did not paste it.

Here is more info about the bash version we're using :

>bash --version
GNU bash, version 2.05b.0(1)-release (powerpc-ibm-aix5.1.0.0)
Copyright (C) 2002 Free Software Foundation, Inc.

Thank you.

ok, try this:

Code:

#!/bin/bash
#set -x
typeset -i currentfiledate=20090220080101
typeset -i reportfiledate=20090219231245

if [ $currentfiledate -gt $reportfiledate ] ; then
     echo -ne "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! \n"
     echo -ne "!! Running the load utility !! \n"
fi

No....

Same error message :

bash: [: 20090220080101: integer expression expected

hm.....
set the 'set -x' option and see what's being executed.
Also make sure there're no 'escape' characters in your script:

Code:

cat -vet myScriptFile.sh

Also, how exactly do you call/execute your script?

Here is the output of the 'set -x' command :

+ typeset -i currentfiledate=20090220080101
+ typeset -i reportfiledate=20090219231245
+ '[' 20090220080101 -gt 20090219231245 ']'
./roger_eod_ofac.cfg: line 6: [: 20090220080101: integer expression expected

Here is the output of the 'cat -vet' command :

#!/usr/local/bin/bash$
set -x$
typeset -i currentfiledate=20090220080101$
typeset -i reportfiledate=20090219231245$
$
if [ $currentfiledate -gt $reportfiledate ] ; then$
echo -ne "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! \n"$
echo -ne "!! Running the load utility !! \n"$
fi$
$

I execute the program using the program name at the prompt 'roger_eod_ofac.cfg' also by preceding the program name with a period '. roger_eod_ofac.cfg'.

Thank you for helping...
