bash string comparison with nested variables -

so i'm quite new bash , im writing basic script run application utility me. want check output specific string response , log if has error. able script working if use line

if [[ $condition == *"added"* ]] ; 

as try exact comparision

if [[ "$condition" == "condition:${2} date:${3} added" ]] ; 

it not work though can see output correct. have feeling im comparing wrong or secrete characters being added bash function havent learned yet. appreciated.

update!

so feedback have been given have tried make code more clear , idea of raw string values are. far replying back. below updated script , output

#!/usr/bin/sh # script posts condition sent shout destination table # in ccm. used generate job_late incidents. # if error encountered logged in # job_late_error_log.txt file. # utility -> ctmcontb -add <condition name> <condition date> # condition format -> l@%%jobname-%%nodeid -> job_late format # $2 = l@%%jobname-%%nodeid $3 = <condition date> cmd_output=$(ctmcontb -add $2 $3) time_stamp=$(date) working_directory=/apps/ctm/devsv/scriptsadmin/do_condition/ error_file=job_late_error_log.txt write_file_to_location=$working_directory$error_file #if [[ $cmd_output == *"added"* ]] ; echo below hex output of "condition:${2} date:${3} added" echo "condition:${2} date:${3} added" | od -xc echo below command $cmd_output echo "$cmd_output" | od -xc cmd_ouput_no_space = "$(echo -e "${cmd_output}" | tr -d '[[:space:]]')" echo below command white spaces removed echo $cmd_ouput_no_space if [[ "$cmd_ouput_no_space" == "condition:${2} date:${3} added" ]] ;     echo $cmd_ouput_no_space     echo successfull ran util     exit 0 else  #   echo $cmd_ouput_no_space $time_stamp >> $write_file_to_location     echo $cmd_ouput_no_space      echo error occurred running util     exit 1 fi 

and output:

im not familiar od -xc call looks values different make sense. not sure why though?

update 2:

so tried removing white spaces using line

cmd_ouput_no_space = "$(echo -e "${cmd_output}" | tr -d '[[:space:]]')" 

that found here:

how trim whitespace bash variable?

but doesn't seem work. have updated original script , ouput @ top of post errors im having.

there space before condition in captured cmd_output.
