Errors in if conditions with to many OR conditions
Hi ALL

I have a script where in i need to check for several values in if conditons but when i execute the script it throws error such as "TOO MANY ARGUMENTS"
Code:
if [ $var1 -gt 1500 -o $var2 -gt 1000 -o $var3 -gt 1000 -o $var4 -gt 1000 -o $var5 -gt 1000 ]
then

msg="BM VAR Issue :: bmaRequestVAR=$bmaRequestVAR , nltBMVAR=$nltBMVAR , bmaResponseVAR=$bmaResponseVAR , bmResponseVAR=$bmResponseVAR , bmRequestVAR=$bmRequestVAR "
SendSms "$msg"
wget -q --no-proxy "http://10.10.1.8/cgi-bin/provider?host_name=LION_MACHINE&svc_desc=MESSAGE_VAR_BM_LION&return_code=0&plugin_output=$msg"
echo "BM Q message sent" >>$monitorLogPath
echo $msg >>$monitorLogPath
fi

ERROR is as follows
Code:
++ '[' 0 -gt 1500 -o -gt 1000 ']'
./QQQ.sh: line 50: [: too many arguments

What about using ||?

use sth like this

Code:
 if [[ $var1 -gt 1500 || $var2 -gt 1000 ]]

I have tested as below. It seems you have a problem in var# variable.
Please check v$varX variable if values are assigned to the varX variable.
Code:
# cat sam.sh
var1=2000
var2=2000
var3=3000
var4=4000
var5=5000
if [ $var1 -gt 1500 -o $var2 -gt 1000 -o $var3 -gt 1000 -o $var4 -gt 1000 -o $var5 -gt 1000 ]
then
  echo "test"
fi
# ./sam.sh
test

Cheers,

@Pamu : no luck yet
@joseph : I did try the way you said, but still there is an issue.

The part of if below has no issue.
Code:
 
if [ $var1 -gt 1500 -o $var2 -gt 1000 -o $var3 -gt 1000 -o $var4 -gt 1000 -o $var5 -gt 1000 ]

Error msg said line 50 so I guess your issue might be in another part of your script.

The script is giving too many arguments error because one or more of your variable value is not set:-
Code:
++ '[' 0 -gt 1500 -o ... -gt 1000 ']'
./QQQ.sh: line 50: [: too many arguments

You can put a check before comparison to see if the variable values are set and then proceed to avoid this error.

From the POSIX spec for test (a.k.a. [):
"the -a and -o binary primaries and the '(' and ')' operators have been marked obsolescent"

Use multiple tests joined by && or ||:
Code:
if [ $x -gt 2 ] || [ $y -lt 99 ] || [ ... ]
then
   :
fi
