So i'm quite new to bash and im just writing a basic script to run an application utility for me. All i want to is then check the output for a specific string response and log if it has an error. Now I am able to get the script working if I just use this line
if [[ $condition == *"added"* ]] ; then
as soon as i try to look for a exact comparision
if [[ "$condition" == "CONDITION:${2} DATE:${3} added" ]] ; then
it does not work even though from what I can see the output is correct. I have a feeling im comparing wrong or some secrete characters are being added which is a bash function I havent learned yet. Any help would be greatly appreciated.
UPDATE!
So with the feedback I have been given I have tried to make my code more clear and get some idea of what the raw string values are. Thanks everyone so far for replying back. Below is the updated script and output
#!/usr/bin/sh
# This script posts a condition sent to it by the Shout Destination table
# in CCM. Used to generate JOB_LATE incidents.
# If an error is encountered it is logged in the
# 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 [[ $cmd_output == *"added"* ]] ; then
echo below is the hex output of "CONDITION:${2} DATE:${3} added"
echo "CONDITION:${2} DATE:${3} added" | od -xc
echo below is the command for $cmd_output
echo "$cmd_output" | od -xc
cmd_ouput_no_space = "$(echo -e "${cmd_output}" | tr -d '[[:space:]]')"
echo below is the command with white spaces removed
echo $cmd_ouput_no_space
if [[ "$cmd_ouput_no_space" == "CONDITION:${2} DATE:${3} added" ]] ; then
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 the output:

job_late.sh[19]: cmd_ouput_no_space: not found
below is the command with white spaces removed
error occurred running util
im not to familiar with the od -xc call but it looks like my values are different which make sense. Not sure why though?
UPDATE 2:
So i tried removing all white spaces using line
cmd_ouput_no_space = "$(echo -e "${cmd_output}" | tr -d '[[:space:]]')"
that i found here:
How to trim whitespace from a Bash variable?
but it doesn't seem to work. I have updated my original script and ouput at the top of this post with the errors im having.
